Bull Owner Testimonials

In 2012, two Star bulls were sold to Dr. Jim Fuller who operates a ranch in Goliad, TX. The droughts of 2009 and 2011 were a wake up call for Jim when he realized that his cows were too large and inefficient. He had to sell about 100 cows. Jim revamped his breeding objective to: breed for a more adaptable and easy care cow herd that involved use of STAR bulls (sired by Honey Bear, a Tuli bull). Jim was also very impressed with the gentle nature of these bulls. A few years later Jim reported: I now have a nice cow herd of smaller framed, polled cows and heifers, mostly slick hided. Both bulls were closely related and had a high level of African genetics. Below are photos of these bulls.
Update – On 16 August, 2018. Jim sent in the email message: “I have been so pleased w/ the retained heifers of the 2 bulls previously purchased  that I would like to slowly convert my herd of about 200.  These heifers have been docile, nice udders, not a single calving problem, seemingly disease resistant, and polled of course… I would like to reserve 3 bulls hopefully for breeding next year.” Below are photos of two of his Star-sired cows:

Update – Between 29 May and June 10, 2020, I received two messages from Jim, which I have combined: “I will be placing these young bulls (photos below) w/ my STAR-influenced herd this week. We have been utilizing a high density multi-paddock system almost 2 years and have been able to nearly double our cow herd. We held last years calf crop over winter on minerals and a smidge of protein. Will continue to retain heifers but should have a good number of heifers for sale next spring. We are not using any wormers or hormones. Over many years I have tried most all common breeds of cattle and am convinced for South Texas these STAR cattle are superior for a low input, grass system. We have no parasite problems, few flies, and easy calving herd. We move the cattle daily and they respect the wire. Our pastures look better than ever even w/ a long period of drought through last winter and this spring.”

Below are photos of two of the bulls that were born in 2018 by Star cows at Lukefahr Ranch and sired by Tarzan, a Mashona bull.


Scarborough Farms consist of cattle and citrus farm business operations in Lake Placid, Florida. Jack and his brother Bob currently run a predominately Angus and Brahman influenced herd. They desire to reduce the Brahman influence largely because of poor dispositions. In search of more heat-tolerant genetics for the Angus base herd, earlier this year Jack came across the Lukefahr Ranch website. Last March a phone order was placed for several Star bulls – before they were even born. Finally on 7 December, a trailer load of 10 bulls left Texas for the approximate 1,250 mile trip to Lake Placid. Upon arrival, Jack commented that by their appearance and behavior they “sure didn’t look as if they had been on a long ride.” Below are photos of their arrival and later being turned out to pasture. This summer, breeding plans include exposing the young Star bulls to many of his cows. In addition, one or two bulls will be mated to a group of South Poll heifers. The resultant cross will have a substantially higher level of African genetics than purebred South Poll to ensure heat tolerance ability and(or) adaptability.
In Fall of 2018, one Star bull and five Star-sired heifers were purchased by Kim Barker who is from Waynoka, OK. Kim desires to breed cattle that are more adaptable and heat tolerant than commercially available breeds such as Angus. Because all surplus Star heifers had already been sold for the year, a set of Star-sired heifers from a local rancher were found. The heifers were mostly out of Beefmaster cows. The local rancher was using his Star bull to downsize his cows to make them more efficient. Once these heifers arrived at Kim’s ranch, his first surprising observation was that they went straight to grazing certain plants species that his own cattle generally avoided. On Lukefahr Ranch, cattle are not fed hay and in winter they graze whatever is available in polyculture pastures. Moreover, cows teach non-selective grazing behaviors to their calves while being wintered. In addition, during winter the cow likely program their fetuses to switch on genes that they will need later for digesting poor quality forage.
Through regular email communications, Kim has often remarked how his  Star-sired heifer are the fattest cattle on his ranch. This is without any pampering or use of fed feeds. He recently sent fecal samples to a laboratory at  Texas A&M University for an analysis. Here is Kim’s response based on the results:
“I did get the fecal samples back. To me there was not any statistical difference. But the STAR heifers sample showed a .06# deficiency in protein, the red angus heifers with them showed a .09# deficiency in protein. Which on one hand is not much difference at all, but on the other hand it is a 50% difference.”
It might be added that despite the 50% difference, the sample size was too small to show statistical significance. Nonetheless, these results may explain in part why the Star-sired heifers maintain better condition. They probably digest better low quality forage, as well as consume a broader variety of plants. Update: in December of 2019, Kim purchased a trailer load of eight Star heifers.
Below is a recent photo that shows two of the Star-sired heifers in the foreground.
In January 2015, two bulls were purchased by Chuck Grimes who owns a Longhorn ranch in Hennessey, OK. Chuck has a degree in Range Science from OK State and worked for NRCS for several years. For several years. he has developed and sold to ranchers a native seed product that has some 90 different (sub)species of native grasses, forbs, and legumes. The two bulls purchased (#10 and 13) were sired by a PCC-R2R Red Angus bull and their STAR dams were a couple of the best cows at Lukefahr Ranch. Chuck’s breeding objective is to cross these bulls with his Longhorn cows to produce replacement heifers and grass-fed beeves. His business goal is to leave behind for his family a sustainable and profitable agriculture business that improves the land. Below is a photo of his Longhorn cattle in one of his beautiful pastures.
Update – On 8 February, 2019, Chuck called to request another copy of the pedigrees on his two bulls to show to other breeders. He told me how pleased he was with his Star bulls that have been very good breeders without any pampering. Now there are many Star X Longhorn heifers in his herd. Chuck really likes how the Star bulls added more muscle and type to the heifers and is looking forward to seeing how well they produce. Two photos are shown below of the two bulls with Longhorn cows and of the heifers.
Dr. Glen Wilkinson is a veterinarian from Premont, TX. For several years now he has fertility tested my yearling bulls. Here is his story about the first Star bull that he purchased in 2015:
“Ten cows. One bull. Out of water four or five days. I went with cubes. Put out cubes. Cows ate until I started running water. All cows, red, brown and black, went to the water. The bull had stayed back eating grass until the cows left the cubes to go to the water. Then he walked over and started eating cubes. By the time the cows were full of water, there were not many cubes left. Cows went to the cubes. He strolled over to the water and drank. I say the bull was more tolerant to the lack of water than the others. The cows were Brangus, Beefmaster, Corriente and mixed crossbred with Brahman influence.” Below is a photo of his Star bull:

Burke Teichert is a well-known and highly respected ranch management expert in the beef cattle industry (watch his video on creating a profitable ranch – link). Last year he contacted me by phone to discuss my novel operation after perusing through my website and reading some of my articles. In May of 2017, Burke paid a personal visit to see my Star cattle and to discuss my management practices. I believe that he was impressed by the clear signs of adaptation of the cattle and how annual production costs have been maintained at approx. $300 per cow. Burke mentioned that he had friends in Missouri that were seeking genetics for heat tolerance and carcass quality (fat on grass) as they were shifting towards a grass-fed production system. He requested that I hold a few good Star bulls to ship later in the fall. Bob and Ann Demerath operate Clear Spring Ranch, Inc., a cow/calf and stocker business located in the beautiful Ozark region near Mountain Grove, Missouri. In Ann’s words: “We are running a mixed herd of black and red Angus/Hereford X with a few A-Beef heifers and some Braford”. Last October, three Star bulls, ranging in age from 1-1/2 to 3 years, were shipped to Clear Spring Ranch. They were turned out a month later on 300 cows for about 90 days. Bob and Ann noted the following: “We had seen a LOT of activity to start and that is slowing down now that most of the cows are bred.  We are breeding for 90ish days, but we sell everything that doesn’t calve in a 60-day window…  the bulls seem to be hard workers, self-sufficient and adaptive”. Below are a few photos of these bulls and their cows.

Billy Griffin is a retired NRCS specialist who now runs a commercial cattle business near Brackettville, Texas. In 2014, he purchased a 1-1/2 year-old bull (LR Wally) whose breed composition is 65.6% Red Angus, 6.3% Senepol, and 28.1% Tuli. His sire was PCC R2R Simon (Red Angus) and his maternal grand sire was Honey Bear (Tuli). Last year, Billy shared this story when Wally was 2-1/2 years old:

Just thought I would send you a quick note concerning the bull 24-13 that I purchased from you. His first calves were born this spring starting in early May. Very happy with the way they look. All were born with no troubles and were healthy and active as newborns. They show good thickness and muscling. Of the 4 Tuli cows that I own, 3 of them had heifer calves and one bull calf. These STAR calves look really good and looking forward to retaining and adding these heifers to my herd. I just took Wally 24-13 in for a Breeding Soundness Evaluation this past Wednesday, July 20th. After over 6 weeks of no rain and 4 weeks of temperatures in the 100 to 103 range every day, he passed his fertility test with no problem. At just over 30 months old, his scrotal circumference was 38 cm, sperm morphology was 85-90% normal and sperm motility was 60%, with all three parameters well above the minimum threshold. His disposition is outstanding! I put in him in pens and load him in to a trailer all by myself with no effort or fuss. In about a week I will put him out with 12 mature cows and 24 yearling heifers, looking forward to see how he handles his job and next year’s calf crop. I am attaching a picture of some of his calf crop from this year plus a couple of pictures I took of him just last week.

Update – On 11 January, 2018, Billy sent in a photo of Wally (photo below). Last year he purchased LR Grey Bull (also shown below) who was used for several years on LR Ranch and is distantly related to Wally. This winter both bulls have maintained great body condition only on stockpiled mature forage with mineral supplements. Last August, Wally’s daughters (most being out of purebred Tuli cows) were bred to LR Grey Bull and will calve next May. Half of these calves are expected to be slick (a gene from the Senepol breed). The breed composition of these calves will be 22.7% Red Angus, 14.1% Senepol, and 63.3% Tuli. The high blend (77%) of Senepol and Tuli will instill both heat and drought adaptation qualities.

Gerry and Janelle Shudde operate a cow-calf operation in Sabinal, located in the central hill country of Texas. They have a very informative website: http://www.shudderanch.com. For years they have used Longhorn cattle to produce all-natural, grass-fed beef. They sell their calves as grass-fed stockers to Parker Creek Ranch, which is managed by Travis Krause. The grass-fed beef is sold directly to customers. Last year in their first visit to Lukefahr Ranch a tour was provided of the Star herd. The Shudde’s were given steaks and hamburger from a Star grass-fed steer. A few days later, Gerry called me to say that the beef was great and that he wanted to purchase a Star bull to cross with their Longhorn cows. Their breeding objective is to produce a grass-fed crossbred beeve that has heat tolerance and greater meat yield. In December 2017, Travis Krause, collected their new Star bull (LR 2-17) and four stocker steers. Below are several photos:

Stephanie May runs a grass-based ranch operation (“Cou Rouge Natural Farms”) in Junction City, AR. Her breeding objective is to have a herd with the right genetics to produce quality beef on pasture without grain. In March 2016, Stephanie purchased a yearling Star bull. Calves are now being born. In a recent email, she provided photos and a few comments about being very pleased with the small calves at birth from her first-time heifers.

Vannie and Julie Collins are from McAllen, Texas. In the photo they are standing before their purchased load of nine 8 month-old Star breeding bulls. Their breeding objective is to use these bulls to downsize their herd of predominantly large-framed, heavy  Beef-master cows to produce replacements that are more moderate in size and efficient in terms of biological production and land utilization.


The photos below are from the Beall family ranch which is located near Cotulla, Texas. In 2013, a yearling bull was first sold to Joe Beall (1st photo). Their breeding goal is to mate grade-type red and black Angus cows to this bull. The cross will be similar to the breed composition of STAR cattle because the bull was a 62.5% blend of Senepol and Tuli breeds. The red- and yellow-colored daughters will be saved for breeding. In the next two years, three more Star bulls were purchased as the herd expanded. In 2015, they purchased a purebred Red Angus bull, PCC R2R Simon from Lukefahr Ranch to breed to Star-sired heifers.

Three years ago, Susan Jerome from Mule Creek, NM, purchased a weaned Star bull whom she named Mars that replaced a 17 year-old Tuli bull,  “Geronimo”. Here is her story:

We have 25 calves, all colors (including a couple of paints!!) 100% calf crop with zero obstetrical events, and 8 of those were heifers!! Two old cows, one of whom is 18 also calved (whoops!). It’s been a great spring. We got about 3″ of rain over the winter, which is wonderful for us, and those little calves are quickly catching up, and all mother cows are in good condition with lots of milk. Most of the calves are red or red/yellow and slick-coated. We have one with scurs (Mama), and 6 with white umbilical/ sheath markings (like Papa). Even my four little black calves have a red cast to them. We lost Geronimo in April, right around his 18th birthday–we miss him, but Mars has certainly stepped up and taken over with no hassles. He’s territorial in relation to the property boundaries, but very easy to work with, and has learned our routines quickly. Hybrid vigor in the proportions we needed and a real pleasure to deal with. Thank you! Enjoying your new website photos and aspiring to a herd as nice as yours!

Last March, six 10 month-old Star bulls and four heifers were sold to Winecup Gamble Ranch. This is a one million acre ranch located in north east Nevada. This historic ranch runs multiple enterprises that include cow-calf, grass-fed stocker and wildlife operations. The ranch has a great website: winecupgambleranch.com. The ranch manager, James Rogers, called me one day and said that he had seen my website and had read several of my articles and wanted to purchase some Star cattle. In NE Nevada it is high desert country. Summer temperatures can be extreme while winter blizzards can be brutal. James expressed an interest in my tropically-based cattle, but requested that the cattle all be hairy so that they could cope with the winter conditions. The breeding objective is to evaluate the Star bull’s fertility and the cow’s productivity and adaptability to this harsh environment. Calves sired by Star bulls will also be evaluated for performance and quality as grass-fed calves. On March 25, the ten head were personally collected by James – following breakfast and a long discussion on cattle breeding at the local Mexican restaurant (El Tapatio) in Ricardo, Texas. Below is a photo of James holding the health certificates, pedigrees and bill of sale, and with the trailer loaded and ready to hit the long journey home. Visit James Rogers Facebook page if you wish to watch a video that shows the young bulls shortly after their arrival on a cooperator ranch in Wyoming en route to Nevada. It had snowed the night before.


Callaghan Ranch is located between Laredo and Encinal in remote south-west Texas. The ranch consists of about 88,000 acres and runs cattle mostly of Hereford, Santa Gertrudis, Brahman, and F-1 breed-types. The manager, Darrell White, is the ranch manager. Darrell is a graduate of the King Ranch Institute of Ranch Management at Texas A&M University-Kingsville. In the past two years, Callaghan Ranch has purchased 6 Star bulls with the primary objective of producing small calves at birth when bred to heifers, as well as producing a good quality market calf. Heifers calve in heavy brush pastures where they cannot be regularly checked during calving season. “It is a low-input heifer development system in which heifers are expected to calve unassisted”. To date, Mr. White is pleased with the birth of many light weight calves. Callahan Ranch also plans to save Star-sired red baldie heifers that display moderate-frame, slick-hided, and drought-tolerant characteristics. Some heifers of this same type may be later sold to interested buyers. Below are a few recent photos.

On December 14, 2015, a visit was made to Edelen Farms, which is a grassfed beef breeding and finishing operation located in Ben Bolt, Texas. The owners, Greg and Lauren Edelen, have purchased several Star bulls over the years. They like the cattle because they are highly fertile, maintain good body condition, and calves easily fatten on grass. The photos below are of the last bull purchased a year ago. His sire was a registered Red Angus bull and his maternal grand sire was a purebred Tuli bull. The bull was exposed to a number of Star-sired cows that had more Senepol influence. The Edelen’s like the gentle disposition of the bull and his nice beef-type conformation.


In the fall of 2009, David and Connie Krider took a long drive south from Seymour, MO. The Krider’s run a commercial herd of cattle (Red Angus- and South Pol-influenced) and they own the Powerflex Fence Company. Improved genetics for heat tolerance and summer fertility was desired for their herd. After an enjoyable visit and tour of my cattle operation, five head of Star calves (3 bulls and 2 heifers) were purchased. Overall, they have been pleased with the heifers that have been good mothers with easy calving ability and tight udders. David also says that they are very easy to get along with and are very low maintenance animals. Recently, he took four top bull calves from his last calf crop and placed them in a pen for a prospective buyer to pick out a replacement bull. He spent about an hour walking around the four in a pen and finally said he could not make up his mind which one was best. So he bought all four! Here is a recent photo of one of the three bulls that the Krider’s bought in 2009 that is now 5 years old.

In May 2013, a Jersey dairy operator out of Columbia, SC, Robert Cely, purchased 2 yearling, slick-hided STAR bulls. Nine months later, calves were being born. Robert’s goal is to add value to his bull calves (a Jersey bull calf brings very low prices at auctions) by keeping the STAR-sired bull calves and grass finishing them on his pastures and selling them when ready for harvest. In 2014 he expanded the goal of phasing out his Jersey herd and replacing them with STAR x Jersey crossbred heifers to establish a new breeding beef herd.  The first two photos show some of these crossbred calves, most of which are slick-coated and well muscled. These are lucky calves indeed to have so much milk! The third photo is a Jersey cow with her crossbred heifer calf.

Chad Wright runs a commercial beef ranch in Hawthorn, OK. Bull calf LR 18-2011 (polled) has a breed composition of 1/2 Senepol, 1/4 Red Angus, and 1/8 Tuli. Bull calf LR 19-2011 (horned) has a breed composition of 1/4 Senepol, 1/8 Red Angus, and 1/8 Tuli from his sire’s pedigree. Both bulls show the double slick-coated condition, numerous vertical skin folds, and good muscling. The bulls were sold in 2011. The photo below was taken in November of 2012. Chad’s breeding goal is to use these small-frame, heat adapted bulls on his predominantly black, large-frame cows in an effort to reduce body size and improve cow efficiency. Chad is particularly pleased with the very gentle nature of his bulls!
