Why Beefmasters?

Why Beefmasters?

Our family has been following a very balanced approach to cattle selection for more than 80 years. We call our road map the Six Essentials, and we have tried doggedly to share it with anyone who will listen for three generations. So it’s refreshing to see a renewed interest in practical and productive cattle and a focus on economics rather than aesthetics.

Breeders sometimes ask, “Why Beefmasters?” It’s an important question because these wonderful cattle often don’t get enough credit for all the subtle things they do so magnificently. Following are a few of the things that make Beefmasters truly unique in beef cattle production.

On the Ranch

  • Low-maintenance females
  • Gentle and responsive handling
  • Excellent mother cows
  • Heat, disease and insect resistance
  • Longevity
  • Built-in heterosis
  • Outstanding replacements

In the Beef Chain

  • High weaning weights
  • Fast-growing yearlings
  • Low sickness and death loss
  • Incredible feed conversion
  • Long-feed efficiency
  • Grade and yield
  • Lean, tender and tasty BEEF

Lasater Philosophy celebrates its 52nd year

Lasater Philosophy celebrates its 52nd year

By Isabel Lasater Hernandez, Vice PresidentEditor’s note: Through various conversations with Mom and Dad, I was able to piece together a time line of The Lasater Philosophy of Cattle Raising journey, which has never been documented.

In February 1971, Laurie Lasater needed a distraction to alleviate the gnawing worry caused by the devastating drought in Coahuila, Mexico. With ranch duties assigned, he came banging in the kitchen door, announcing that he was going to write about his father. Initially, Laurie planned to write a short pamphlet summarizing Tom Lasater’s ideas—he estimated that he would need two pages—and make copies for his family and friends.

As Laurie began writing about the Six Essentials, he thought of more of Tom’s ideas that he wanted to include. With the encouragement of friends and family, the article became several chapters that eventually became a book.

Laurie worked on his first draft from February to May, waiting for the drought to end and their second child to be born. In June, Laurie and Annette spent three weeks in Eagle Pass and Del Rio, Texas border cities near the hospital in Piedras Negras, making sure they were close to the doctor. Annette used the monotonous days to retype and finalize Laurie’s manuscript.

Laurie, Annette, Lorenzo and Isabel at Rancho Santa Cruz in 1972, the year The Lasater Philosophy was first published.

The rain began falling in Piedras Negras when Annette was in the hospital. She and Laurie hoped it was raining at Rancho Santa Cruz, their home nearly three hours away. Little did they know that the ranch was in deluge that would total more than 30 inches of rain. When they flew home several days later, the ranch was unrecognizable from the air, with landmarks and fences washed away and debris scattered everywhere. Laurie had managed to finish his manuscript just as the historic drought ended.

During a trip to Albany, Texas, to visit family at Lambshead Ranch, Laurie’s grandmother Ethel Matthews Casey suggested he contact Carl Hertzog, founder of Texas Western Press, about his book. An award-winning book designer, Carl had created a new edition in 1958 of Interwoven, written by Laurie’s great-grandmother Sallie Reynolds Matthews. According to an article by the Texas State Historical Association, Interwoven was Carl’s “sentimental favorite above all others.”Laurie told Carl about his manuscript, but initially Texas Western Press passed on the project as they wanted to focus more on history books. However, Carl later decided to take on the ranching book. Carl expanded the project further, designing a limited, boxed hardcover edition of 295 copies, followed by a hardcover version and eventually a paperback. The boxed books, released in 1972, were signed by Laurie, Carl and Tom Lasater, making them especially unique.

Texas­­­­ Western Press continued publishing the paperback edition of The Lasater Philosophy of Cattle Raising until 1992, calling it one of TWP’s “all-time bestselling books” on the back cover.

Twenty years is an incredible run for any book, but The Lasater Philosophy’s story was not finished. In the mid-1990s the book’s rights reverted back to Laurie, and during a visit to San Angelo, Marcos Giménez Zapiola, a rancher from Argentina, suggested they translate the book into Spanish. The two men decided to collaborate on an expanded edition. Leaving the original manuscript largely unchanged, they added a new section which featured a selection of Laurie’s speeches given between 1982 and 1993. These writings addressed current challenges of the cattle industry and almost doubled the size of the book.

Marcos edited the new section and then translated the book into Spanish, making the first-ever Spanish edition in 1999. He then translated it back into English to create an expanded, Millennium Edition that was first published in 2000.

Today, older editions are traded in collector book circles, with early copies listed for upwards of $400. The Lasater Philosophy has been featured in university agriculture curriculums, and every week the Isa Beefmasters store ships orders as far away as New Zealand and Thailand.

This year marks the 52nd anniversary of The Lasater Philosophy’s publishing with its 17th edition. Rarely does a book enjoy a successful run spanning so many decades. The book’s continued longevity proves that Tom Lasater’s ideas remain as relevant today as they were groundbreaking during his career. In his preface, Laurie writes about the book: “After my family, and in spite of my dreams of ‘empire building,’ it has probably been the great accomplishment of my career.” In a 50-year career with many highlights, that is high praise indeed.

Press release

Isa Beefmasters LLC’s 63rd Beefmaster bull sale was held October 5th in San Angelo, Texas. It was an excellent sale, with 29 buyers from six U.S. states and Mexico taking home 82 Beefmaster bulls at an average of $7434. Isa President Lorenzo Lasater stated the sale was their highest average to date, with excellent demand for good Beefmaster genetics. Auctioneer Joe Goggins of Billings, MT, sold the 82 bulls in the blistering time of 1 hour, 40 minutes.

The high-selling bull, L Bar 3129, sold to San Pedro Beefmasters of Texas for $25,000. This awesome young herd-sire prospect is the son of L Bar 7301 and L Bar 1205 and was one of the overall top performers in the offering.  He is headed for immediate collection at Elgin Breeding Service.

L Bar 2081 was one of the high-selling bulls in the company’s 63rd bull sale.
The second high-selling bull, L Bar 2503, sold to Marcelo Madro of Mexico for $17,000. This excellent bull was another top performer and sired by L Bar 9456. It is worth noting that both high sellers are sons or grandsons of the great L Bar En Fuego, who sold in this sale in 2011. He has sired many high sellers since, and now his descendants are ringing the bell. A truly remarkable genetic line.

Volume buyers included: Diamond and a Half, NM – 9; Jody Wedgeworth, TX – 9; Seminole Tribe, FL – 7; Kellis Ranch, AZ – 7; Lykes Brothers, FL – 6; Rafter T, FL – 6.

Current Isa president Lorenzo Lasater and his sister and partner, Isabel Hernandez, represent the fourth generation of the family dedicated to breeding performance Beefmaster genetics. The breed was founded by their grandfather, Tom Lasater, in 1937.  This year marks the 87th anniversary of the breed. It is also the 132nd anniversary of the L Bar brand, which was first used by Ed Lasater in 1892 in South Texas. It has been used continuously since by five generations of the family in Texas and Mexico.

According to Lorenzo, “This set of bulls represents over 87 years of consistent, balanced selection for economically viable cattle. These bulls will produce excellent feeder calves and replacement heifers in any environment, but especially the tougher ones. With more pounds at weaning, lower input costs, more longevity and the best mother-cow on the planet, Beefmasters can’t be beat.”

Beau Lasater, Lorenzo Lasater and ranch foreman Todd Bannert
The Lasater family would like to extend their heartfelt thanks to everyone in attendance, especially the many repeat customers, including several second- and third-generation buyers. We are already working hard to bring you our 64th set of Beefmaster bulls on October 4, 2025.

Harnessing the power of ranching’s new A.I.

From the Spring 2024 issue of the Isa Informer

Harnessing the power of ranching’s new A.I.

By Lorenzo Lasater, President

Full disclosure: I asked Chat GPT (A.I.) to research this article. If you haven’t tried it out, do so. It provides information similar to a Google search, without the dozens of ads you have to sift through to find the answer.

I’ve written a lot about A.I. (artificial insemination) through the years, but the other A.I.—or artificial intelligence—is all the buzz lately. But what does it mean for an ancient craft like cattle raising? That’s still a bit fuzzy, but the possibilities are intriguing.

A.I. excels at analyzing tons of data and spotting trends, irregularities or anomalies. It can complete this analysis very quickly, and that information can then be harnessed to make routine decisions or anticipate trends or automate processes that used to require a person. As you can tell from past discussions on technology, I am a huge fan of using available tools to improve processes and move things more efficiently. But A.I. is still in its infancy and hard to wrap our minds around.

What do possible applications look like for the cattle rancher in the future? Following is a list of ways that A.I. could assist in herd management:

• EPD analysis
• Genomic selection
• Grazing management
• Counting and tracking cattle
• Analyzing customer buying habits
• Anticipating market trends
• Health management
• Optimizing nutrition levels and feeding schedules
• Weather and environmental data to anticipate drought
­­­­• Automated sorting for weight and finish
• Drone cameras
• Heat detection and breeding timing
• Pregnancy detection, including fetal age and sex
• Analyzing herd historical records to find outliers

I created this robot cow graphic using A.I. on www.copilot.microsoft.com. I literally said “draw a robot cow” and got this image 12 seconds later.

Cool, huh? But what about its actual uses today? Following are some real-world A.I. examples Isa Beefmasters employs:

We began using Ranchbot (www.ranch-bot.com) remote water monitoring devices last year and love the technology. The windmill in the image is about an hour and a half from my house, at the absolute back of the ranch over rough ranch roads. Someone must drive all the way back there several times a week, just to be sure it is pumping. Now, we get an automated alert if it falls below a critical level (indicating windmill down) or falls rapidly (leak). We can also utilize the technology to switch pumps on and off automatically at predetermined levels. It also functions as a rain gauge. Checking rainfall from my bed is a new favorite!

At the recent NCBA convention in Florida, we visited the 701X booth (www.701x.com). They have developed GPS tags specifically for bulls. The tag tracks their location, movement, and breeding information. It uses accelerometers to know when a bull mounts, so you can see remotely which bulls are working and which are not. If they stop moving you are alerted to a problem immediately, and if they get out of the pasture, you can find them more easily. We will be implementing this technology for the spring breeding season. Watch for updates!

Additionally, we use CattleMax software (www.cattlemax.com) for managing our herd inventory. I put a lot of thought into herd information and collect a lot of data on each calf crop, but then we file those spreadsheets away at weaning. Traditionally, there was not a connection between the years. Cattlemax reporting has helped us deep-dive into the historical data to highlight trends in growth and fertility, as well as identify outliers in the cow herd.

Ranchbot remote water monitoring provides us with real-time readings for our hard-to-reach tanks.
Drovers magazine recently published an interesting piece on using facial-recognition cameras to predict pinkeye in confinement cattle 99.4% of the time and several days before veterinarians were able to detect symptoms. (Editor’s note: Beefmasters have a natural resistance to pinkeye.)

According to Mike Clawson, a USDA Agricultural Research Service molecular biologist and project researcher, “Early detection of disease is critical to healthy herd management—giving producers the chance to separate sick animals, control spread and judiciously use antibiotics before a large outbreak occurs.” You can read the complete story on www.drovers.com in the article titled “Study Confirms Facial Recognition Technology’s Success in Disease Prediction.”

Artificial intelligence is the new frontier in data management. While still in the very early stages, this incredible technology can wield much power in beef cattle production. Isa Beefmasters is proud to be “early ­­­adopters” of new technology, and we look forward to seeing what the future holds. The possibilities are limitless, and I think the Beef industry needs to embrace the change to remain competitive.

Building on a Beefmaster legacy

From the Fall 2023 issue of the Isa Informer

Building on a Beefmaster legacy

By Isabel Lasater Hernandez, Vice President

A 1994 article in The Cattleman magazine called our dad, Laurie, “the Conservative Keeper of the Flame.” An interesting premise at the time, the term has gained even more significance in the ensuing 30 years as our family has worked tirelessly to expand upon the legacy of our predecessors.

120 Years Ago  

In the late 1800s, our great-grandfather Ed C. Lasater began amassing land and cattle in the rugged brush country of South Texas. He helped establish Brooks County and the town of Falfurrias and was one of the first cattlemen in Texas to use Bos Indicus cattle. Eventually he owned 380,000 acres of ranchland, approximately 20,000 registered Hereford cattle and at one point the largest herd of Jersey cattle in the world.

In addition to ranching, he served as president of TSCRA in 1911–1912 and frequently traveled to Washington, DC, to lobby for the beef industry.

Sadly, much of Ed’s business was lost when he died in 1930 and the ranch suffered during the Great Depression.

90 Years Ago

After Ed Lasater’s death, our grandfather Tom Lasater withdrew from Princeton University in 1931 and returned home to the Lasater Ranch in Texas to begin picking up the pieces of the family business.

In 1932, Tom initiated his crossbreeding program that would eventually lead to Beefmasters: He crossed his father’s Brahman herd with the Hereford herd, as well as with Shorthorn cattle Tom had purchased. He then crossed those two F1 herds and quickly discovered that the three-way Brahman/Hereford/Shorthorn composite outperformed the two-way crosses. Tom closed his herd to outside genetics in 1937 and christened his breed of efficient cattle Beefmasters.

A 1956 article in The Farm Quarterly called Tom a “straight-talking, controversial figure in cattle circles with a bagful of off-beat ideas that leave the conventional cattle breeder in a state of shock.” I’d like to think Granddad would have laughed when he read that description. We in the Beefmaster breed know that regardless of public opinion, Tom unapologetically stuck to his (then) unorthodox ideas: ruthless culling, competitive multi-sire breeding, defined breeding seasons, performance testing, weighing calves and, of course, his cornerstone principles, the Six Essentials.

 

60 Years Ago

While Tom forged a new path in his quest for highly efficient cattle, his oldest son, Laurie, blazed new trails in expanding Beefmasters’ reach. Nearly 60 years ago, our parents, Laurie and Annette, began their Beefmaster career in Mexico with a wedding gift of 35 Beefmaster cows and two bulls from the Foundation herd. Laurie’s dream was to carve out his own niche and establish a market for purebred Beefmaster cattle in Mexico. Today Beefmasters have the highest number of registrations of any beef breed in that country.

In addition to opening new markets, Laurie wrote The Lasater Philosophy of Cattle Raising in 1971. He started writing during a drought when he needed a distraction to occupy his mind. The book, which explains the family’s cattle-raising ideas, still sells 50 years later, and in the book’s preface Laurie calls it the “great accomplishment of my career.”

30 Years Ago

Thirty years ago our family experienced a banner year of celebration and change. In May 1993 we gathered for two graduations and one wedding: I graduated from Vanderbilt University, the next week Lorenzo graduated from TCU Ranch Management School, and a week later he and Leslie married. It was certainly a whirlwind month!

With our newly minted degrees, Lorenzo and I both assumed new roles in the company: I took over the advertising for Mom, and Lorenzo, full of new ideas from Ranch Management, joined as the Vice President of Operations.

During his 30 years, Lorenzo’s role has evolved with his goal of expanding the Beefmaster footprint worldwide. He has traveled to six continents and 15 countries to promote Beefmasters and educate cattlemen around the world. Today, there are L Bar Beefmaster genetics in at least 25 countries.

Tom Lasater remained laser-focused on innovation and improvement throughout his career, and his generation did the tough work of creating and refining Beefmasters into the high-performing animals they are today. Building on those successes, Lorenzo has worked to increase our herd’s uniformity. For the past 20 years, he has streamlined our herd by eliminating the off colors frowned upon by the beef industry and ensuring our customers’ feeder cattle will grade well, all within the demanding focus of the Six Essentials.

Of all his initiatives, Lorenzo is most excited about seeing the Beefmaster breed expand and gain respect worldwide.

Today

Exactly 30 years after Lorenzo and I started at Isa Beefmasters, we are excited to announce another milestone for the company: Lorenzo’s son, Beau, has joined the operation, taking the reins for the fifth generation.

After graduating from TCU, Beau worked at American Airlines and Aldi Grocery Stores, gaining invaluable and diverse corporate experience. He then decided he was ready to return to his childhood roots. The sixth generation is also on the ground in Beau’s and Paige’s children, Jaxon and Ellie.

While we are proud of our family’s 131-year Legacy and Longevity, we are most excited to look to the future with the next generation in place.

Beefmasters grading 94% choice silences critics

From the Spring 2023 issue of the Isa Informer

Beefmasters grading 94% choice silences critics

By Lorenzo Lasater, President

Isa Beefmasters is pleased to report some exciting results in two separate research projects. The results are a testimony to the investment we have placed in pushing the genetic envelope and making L Bar Beefmaster genetics ever more useful to the beef cattle industry worldwide. I’ll examine in this article the Noble Research Institute study in Ardmore, OK, which focuses on replacement females and carcass data.

When we talk to commercial cattlemen about using Beefmaster bulls in place of their current breed, they often raise two common concerns:

1. Will they color up the calves?

2. Will they grade?

As our customers know, Isa Beefmasters has been working on color-uniformity for most of my career. We have eliminated any kind of paints, brindles or other color patterns the commercial sector dislikes. About 5% of the bulls we sell annually might have a small amount of white on their belly or face, but that is the extent of it. If you breed L Bar bulls to solid black or red cows, you will get solid-colored calves.

This Beefmaster x Angus cross heifer is part of a study at the Noble Research Institute in Ardmore, Oklahoma.

As to the second question, the prevailing thought is the Brahman-influenced or Bos Indicus-influenced cattle will have low-quality grades. This issue is true in some breeds, and certainly true of some genetic lines within breeds. As we’ve heard it said: There is more quality variation within one breed than between quality cattle of different breeds. Overall quality can vary significantly depending on the program and what the herdsman considers important.

At Isa Beefmasters, we believe the success of the commercial beef cattle producers who buy our bulls is important. We want them to provide calving ease, adaptability, growth, and heavy, healthy calves to the weaning pen. We want the feeder steers to gain fast, convert efficiently, be sickness free, and grade and yield well. We want the replacement females to be fertile, early maturing, easy-keeping, gentle, and have long productive lives raising big calves. To me, these things make beautiful and profitable cattle. The loyal customers who buy our bulls feel the same.

In order to answer the quality grade question more directly, we are in the process of feeding several groups of sire-identified calves in order to get the hard data. We have always had customers say, “My calves graded 75%,” so we knew L Bar Beefmasters were not hurting the grade, but those numbers are anecdotal, not scientific.

In 2020, we began a collaboration with Beefmaster Breeders United and the Noble Research Institute. They used two leading Beefmaster bulls (L Bar En Fuego, C988569, raised by Isa Beefmasters and owned by Gene Haymon; and CF Nueces, C1059662, raised by Collier Farms and owned by Jim Colvin). The sires were A.I-bred to Noble’s commercial Angus herd. Noble’s initial intent was to develop and study the replacement females, which is still ongoing.

In 2022, BBU was able to buy, feed and harvest the steers, with some truly fantastic results. As you can see in the chart on p. 1, the steers gained 4.47 pounds per day, finished in 160 days (30 days faster than projected), had 0% death loss, yielded 62.6% and graded 94% choice (industry average 75%). Additionally, West Texas A&M University conducted Warner Bratzler ­­Shear Force (WBSF) tests, and the steers averaged 3.86kg. (Anything under 4.6kg is considered tender.) This phenomenal performance shows what can be achieved utilizing performance Beefmaster genetics in your crossbreeding program.

In summary, the fact that these steers graded 94% choice (against an industry average of 75%) clearly answers the “will they grade” question. But we have long maintained that there is more to profitability than just quality grade. These results show that true success lies in a combination of feedlot performance, health, grade and yield, and the critical, but hidden, trait of tenderness. These Beefmaster-sired steers absolutely rang the bell in every phase.

Study finds Beefmasters thrive in tropics

Study finds Beefmasters thrive in tropics

By Roderick Gonzalez Murray, Ph.D., IDIAP* Panama
and Sergio Riveron Ponomarenko, Isa Beefmasters

The Beefmaster breed has proven through various studies to be the most efficient breed for beef cattle production in the many diverse ecosystems of the United States—from the arid desert to subtropical Florida, to the northern states with their harsh winters. But a new study in Panama shows Beefmasters achieving excellent results in the hot and humid tropics, one of the most difficult environments for cattle production.

A Beefmaster-cross cow in Panama.
The Institute of Agricultural Innovation of Panama of Panama (IDIAP), at its Gualaca Research Station located in the province of Chiriquí, ­carried out a research project between 2000 and 2022. Researchers studied the effect of crossbreeding 14 different beef breeds on IDIAP’s herd of crossbred commercial cows. Scientists recorded 2,843 data points to evaluate the Age at First Calf (AFC), Calving Interval (CI), Birthweight (BW) and Weaning Weight (WW) performance.
We are pleased to report the excellent results of Beefmaster production in the tropics, as well as the specific performance of Isa Beefmaster’s herdsire L Bar En Fuego in this study (results outlined at right).

After analyzing the results, IDIAP researchers concluded that 50% crossbreeding of Beefmasters in commercial herds has a positive influence on the indices studied. They also found that as the percent of Beefmaster blood increases in the same commercial herds, reaching 75%, the improvement of all the indices is much higher.

This study is the first to evaluate the impact of Beefmaster genetics on beef cattle production in the tropics. The cattle clearly performed well in all the phases most relevant to profitability. These results demonstrate that the Lasater Philosophy, with its Six Essentials, is the best method to maximize economically important traits in any environment.

Artificial insemination: a natural winner

From the Fall 2022 issue of the Isa Informer

Artificial insemination: a natural winner

By Lorenzo Lasater, President

One of the most valuable genetic tools available to ranchers is artificial insemination, or A.I. In fact, there are so many benefits, using A.I. is a natural choice, even in a commercial operation. For example, A.I. allows the use of the very top genetics, it groups the calves closer in age and front-loads the calving period, and it means fewer bulls have to be turned out.

In addition to these advantages, A.I. enables an operator to multiply the influence of a top sire—beyond what that bull could contribute naturally, and maybe best of all, operators gain more predicable genetic movement using higher-accuracy EPDs.

At Isa Beefmasters, we have been incorporating A.I. into our herd planning for decades. Dad first learned the technique in 1964 at the Graham School in Garnett, Kansas. He began using A.I. in our registered herd in Mexico in 1965. This year marks 57 years of continuous use of this incredible technology!

Thisbeautiful A.I. daughter of L Bar Momentum recently sold for a premium at the Red River Performance Group Heifer Sale.

To quantify our R.O.I. on A.I., I did a little analysis on two groups of cattle, recently sold, in which Isa Beefmasters was involved.

The first sale occurred at the Red River Performance Group Heifer Sale held May 21, 2022. We were pleased to consign three L Bar heifers to the sale, which featured 76 excellent quality, performance-tested open heifers. The sale averaged $3567, a tremendous price for that number of open heifers. The high seller brought only $7300, making this an honest average.

In a previous article published in the Fall 2020 Isa Informer, I estimated that it costs around $82 to A.I. a registered cow, including semen. In this case, that was $82 well spent, yielding a net gain of $116 on the heifers on the sale. L Bar-sired heifers fared even better, netting an additional $494 over the sale average after the cost of the A.I.

LBarMomentum brings extremely balanced EPD power to his progeny. A.I. allows any-sized operator to harness the same genetic power that large seedstock producers use.

I want to congratulate the Red River Group on their “Genetic Partnership,” in which they have partnered with breeders who have semen sires they believe will help the program and have made the semen available at a discounted price to their members. Isa Beefmasters is proud to have L Bar En Fuego and L Bar Momentum included in the partnership. Red River encourages their members to A.I., which in turn improves the quality and consistency of the bulls and heifers sold. That value extends to their own replacement heifers, with the accuracy and quality of their herd EPDs increasing rapidly. To learn more about the program, visit: www.redriverbeefmastersale.com

We experience a similar financial boost in our own annual bull sale. At Isa Beefmasters, all our cattle are generically named L Bar plus a 4-digit number (e.g., L Bar 2104). We only name the semen sires, so they are easily identifiable. Though most of the bulls we sell each fall go into commercial operations, the buyers recognize the additional value and predictability of those A.I.-sired bulls and will pay more for them.

The chart at right details our 2021 bull sale results. You can see a $484-per-head advantage for the A.I.-sired calves, which is a welcome boost to the bottom line.

Bullbuyers recognize the value of A.I.-sired bulls and are willing to pay more to gain the genetic insights and predictability that A.I. offers.

Producers often cite cost, labor and facilities as the usual reasons why they do not use A.I. I will admit that it is a bit labor intensive, with most protocols requiring three or four trips down the chute. But the rewards far outweigh the work, and you will likely be working them at least once pre-breeding anyway. At $82 per head, the cost is manageable, especially when you crunch the numbers.

A.I. is a tremendous tool for making faster genetic progress in any operation that is willing to put in the extra effort. You will be able to use superior genetics, tighten your calving window, increase your pregnancy rates and reduce your bull needs. It is not without some extra labor and expense, but it really is a winning strategy that more than pays for itself and yields many important benefits. In these two examples, you can see how the effort was well rewarded, adding significant value the final product—a financial boost I will gladly pocket any year.

Press Release—January 12, 2023

Isa Beefmasters is pleased to report on the culmination of two significant research projects. Each one is a testimony to the investment we have placed in pushing the genetic envelope and making L Bar Beefmaster genetics evermore useful to the commercial cattle industry worldwide.

In both studies, we will provide full details in our upcoming Spring Isa Informer newsletter. But we wanted to give a sneak peek at this tremendous news.The first involves a collaboration with Beefmaster Breeders United and the Noble Research Institute in Ardmore, OK. They used two leading Beefmaster bulls (L Bar En Fuego, C988569, raised by Isa Beefmasters and owned by Gene Haymon; and CF Nueces, C1059662, raised by Collier Farms and owned by Jim Colvin). The sires were A.I. bred to their commercial Angus herd. Noble’s initial intent was to develop and study the replacement females, and that is still ongoing. But BBU was able to buy, feed and harvest the steers, with some truly fantastic results.

Steers at Nextgen Cattle Feeding, KS.

The Executive Summary: The steers gained 4.47 pounds per day, finished in 160 days (40 days faster than projected), had 0% death loss, yielded 62.6% and graded 94% choice (industry average 75%). Additionally, Warner Bratzler Shear Force (WBSF) tests were conducted by West Texas A&M University, and the steers averaged 3.86kg. (Anything under 4.6kg is considered tender.) This phenomenal performance shows what can be achieved utilizing performance Beefmaster genetics in your crossbreeding program.

Isa President Lorenzo Lasater commented, “We have long maintained that there is more to profitability than just quality grade. These results show that true success lies in a combination of feedlot performance, health, grade & yield, and the critical but hidden trait of tenderness. These Beefmaster-sired steers absolutely rang the bell in every phase.”

The second progeny test took place in Panama between 2000 and 2022. The program included 13 breeds and measured 2843 calves. Ten Beefmaster sires were used on native Zebu or Brahman-cross cattle. The intent of the study, which is ongoing, is to examine improving reproductive efficiency and increased growth as a means of improving profitability for beef cattle producers in the tropics. The study was conducted at the Gualaca Livestock Experiment Station by IDIAP.

The Executive Summary: The study showed that for AFC (age at first calf) Beefmaster crosses were the best among the 13 breeds, while birthweights held steady, and growth was significantly increased. The scientists are very excited about the significance of the results as it pertains to beef production in the tropics, where 80% of the world’s cattle reside. More importantly from our perspective, Isa Beefmasters sire L Bar En Fuego was the number one Beefmaster sire for both AFC and weaning weight.

Isa President Lorenzo Lasater commented, “The cattle industry often loses sight of the fact that profitability at the cow-calf level is predicated on low-input cattle that can handle their environment, reproduce efficiently, and wean heavy calves. No female is better at this than a Beefmaster.”

We look forward to sharing the full results in our Spring Isa Informer. We are proud of how well Isa Beefmasters genetics performed in both progeny tests. While they encompass very different aspects of Beef Cattle production, they examine several fundamental concepts in successful operations: reproductive efficiency, adaptability, growth, health, and carcass quality.

Building brand equity for 130 years

Building brand equity for 130 years

By Laurie Lasater, Founder

It’s hard to fathom, but our family’s use of the L Bar brand dates back almost to the Civil War, with it first appearing in the 1870s. Since then, four generations of Lasaters have branded tens of thousands of cattle with the iconic mark, both in Texas and in Mexico.

Starting in South Texas

In 1892, my grandfather Ed C. Lasater first registered the L Bar brand in Falfurrias, located in South Texas’ rugged cattle country. Ed founded the town of Falfurrias, as well as Brooks County, which he named for his friend Judge John Brooks. He was determined to build his empire there and began amassing land and cattle.

At its height, Ed’s La Mota ranch measured 380,000 acres, making it one of the largest in Texas. Ed became well known for his large herds of high-quality Hereford and Shorthorn cattle, and he imported the first Brahman cattle into South Texas. In addition, he owned the largest Jersey herd in the world and founded Falfurrias Creamery Company, and the name Falfurrias became synonymous with its sweet, creamy butter.

Ed C. Lasater first registered the L Bar brand in 1892 in South Texas.

Surviving the unthinkable

Ed died in 1930 and much of the ranch and cattle were swallowed up by the Great Depression. His youngest son—and my father—Tom Lasater left Princeton University in his sophomore year to return home and salvage what he could of the family business. It was during this period of economic catastrophe that Beefmasters were born: Tom experimented with crossing various of his father’s remaining cattle. He quickly discovered the Shorthorn/Hereford/ Brahman three-way cross was far superior to other crosses he tried. They say necessity is the mother of invention, and Beefmasters were tested and honed during this most dire economic period of the 1930s and 1940s.

In 1937, Tom closed his herd to outside genetics, and in 1948, he relocated his Beefmasters to Matheson, Colorado, to escape the ongoing frustration of Hoof and Mouth disease coming across the Mexican border. He purchased the former Matheson Ranch on the eastern plains near Colorado Springs and continued his development of Beefmasters. The USDA formally recognized Beefmasters in 1954, making it one of the first American composite breeds.

Heading south of the border

Ten years later, I picked up the mantle of the brand, taking L Bar, my new bride and 35 Beefmaster cows to Mexico. In 1964, I registered the brand in the northern state of Coahuila.

Tom Lasater, youngest son of Ed C. Lasater, returned home after his father’s death in 1930 to try to save the family ranch and cattle.
I sold my first L Bar Beefmaster bull calves to three ranchers for $5,000 pesos ($400) each. The neighborhood could not believe the high price paid by prominent ranchers! Each year I bought 50 weaned bull c­alves from The Lasater Ranch and sold them to Mexican ranchers in several areas.

In 1966, with backing from investors in Midland, Texas, I bought the 31,500-acre Rancho Santa Cruz near Múzquiz, Coahuila, and we expanded our herd to 400 cows. When we decided to return home after 10 years, I sold the cattle to Guillermo Osuna and the ranch to Vidal Gonzalez, both neighboring ranchers.

Returning home to Texas

When we relocated back to Texas in the 1970s, I registered the brand in Irion County in West Texas.

Today, our children, Lorenzo and Isabel, are the fourth generation of Lasaters to raise cattle under our beloved brand. They have reg­­istered the L Bar brand in the nine counties in which they operate, ranging from Sutton County, south toward Mexico, to Titus County, northeast of Dallas.

I am proud of the fact that I was able to use the L Bar brand for 50 years in Mexico and Texas and be part of its storied, 130-year history.

Press release

Isa Beefmasters LLC’s 61st Beefmaster Bull Sale was held on Oct. 1, 2022, in San Angelo, Texas. It was an excellent sale, with 33 buyers from six states and Mexico taking home 100 Beefmaster bulls at an average of $5840. Isa President Lorenzo Lasater stated the sale was their highest average to date, with excellent demand for good Beefmaster genetics. Auctioneer Joe Goggins of Billings, MT, sold the 100 bulls in the blistering time of 1 hour, 45 minutes.

The high-selling bull, L Bar 0501, sold to Danny Major of Chino Valley, AZ, for $18,000. This awesome, young herdsire prospect is the son of Schneider 0481 and L Bar 8440 and was one of the overall top performers in the offering.

The second high-selling bull, L Bar 0548, sold to San Pedro Ranch of Carrizo Springs, TX, for $16,000. This excellent bull was another top performer and sired by L Bar 6105.

It is worth noting that both high sellers are sons and grandsons of the great L Bar En Fuego, who sold in this sale in 2011. He has sired many high sellers since, and now his descendants are doing it. A truly remarkable genetic line.

Volume buyers included: Rafter T Ranch, FL—12; A. Duda and Sons, FL—10; Ray Corona, FL—10; and LE Ranch, NM—9.

Current Isa president Lorenzo Lasater represents the fourth generation of the family dedicated to breeding performance Beefmaster genetics. The breed was founded by Lorenzo’s grandfather Tom Lasater in 1937. This year marks the 85th anniversary of the breed. It is also the 130th anniversary of the L Bar brand, first used by Ed Lasater in 1892 in South Texas. It has been used continuously since then by four generations of the Lasater family in Texas and Mexico.

According to Lorenzo, “This set of bulls represents over 80 years of consistent, balanced selection for economically viable cattle. These bulls will produce excellent feeder calves and replacement heifers in any environment, but especially the tougher ones. With more pounds at weaning, lower input costs, more longevity and the best mother-cow on the planet, Beefmasters can’t be beat.”

The Lasater family would like to extend their heartfelt thanks to everyone in attendance, especially the many repeat customers, including many second-generation buyers. We are already working hard to bring you our 62nd set of Beefmaster bulls on Oct. 7, 2023.
