Bulls for Sale



Posted below are photos taken of the best set of bulls that are being offered for sale. Additional bulls will be added later. These calves are mostly 3 to 4 months old at this time. Even at this early age these calves show strong African genetic influence and a high degree of uniformity that reflects years of selective breeding for high fertility and production under hot tropic-like conditions. Composite-bred Star cattle are highly heat tolerant and drought adapted. Star cattle are Texas-bred but with a high degree of African genetics. For the bulls shown below, their sires were born and bred in Texas, or if an AI sire was involved, the breed was either from Africa (Mashona) or the Caribbean (Senepol). Many ranchers have operations in regions that for several months of the year become like those of the tropics. Star cattle are heat tolerant and perform well in states like Arkansas, Missouri, New Mexico, Oklahoma, and South Carolina, especially when the breeding season is in the summer. They have also been reported to do well in fescue country. When purchasing a bull know that bulls drive the genetics of the herd!

This set of calves will be ready for service as breeding bulls by summer of 2019 if not sooner. In previous years, ranchers have made a partial purchase of a bull calf with a deposit check (“presold”). Of course they had to wait until the late fall when the calf was old enough to wean before setting a pick up date. Discounts are given to repeat customers and to those who buy more than one bull. Bulls 7, 24 and 30 are still available. (Bull 24 was previously presold but the buyer traded him out for a 1-1/2 year-old Star bull that was breeding my heifers.)

Over the years, most bulls have been picked out from this website, followed up by a phone call or an email, even without making a trip in person to Lukefahr Ranch. Upon request, more information and photos can be sent. For those ranchers who wish to develop their bulls and acclimate them to their new environment, some bull calves will be picked up later this fall shortly after weaning. However, a few bulls will be wintered on their dams and sold closer to one year of age (some ranchers even use them lightly at this age) – just a few months prior to summer breeding. For years now, 14 and 15 month-old bulls have been used on Lukefahr Ranch to breed cows and heifers during the summer breeding season (mid-July through August) so that calves will be born mostly in May.

The following preliminary table of  parentage, scores, weights, and EPDs has been prepared. It will be updated as the bulls continue to develop. Additional bulls will be added later to the table. In the Spring 2018 genetic evaluation, EPDs were computed for all traits even though only birth weights had been measured. The interim WW, Milk, and TM EPDs were computed based on correlations between these traits with birth weight and based on the contribution of EPDs from relatives.

The three following bulls were presold by private treaty.

Next is a photo gallery of the five featured sires of the 2018 calf crop. Two AI sires were used: Schuler Rebel (Red Angus) and WC 950K (Senepol), and three by natural service. Tarzan – a Mashona purebred – is dark red. This bull will add even more African genetic influence and vigor to the Star composite herd. Star herd sires LR 23 (LR Dahga) and LR 30 are both homozygous for the slick gene. For the 2018 calf crop, the combined composition of heat-tolerant Senepol, Tuli, and Mashona breeds is, on average, 66.1% (if Mashona-sired the range is from 64.1 to 89.1%). Most calves are slick-coated and some calves have over 75% African genetics with a maximum load of hybrid vigor. In addition, most of this year’s calves show extensive muscle development, even more than that commonly found in purebreds. I attribute this level of expression to breed complementation – due to the combination of the best genes for extensive muscling from the Senepol and Tuli (and now Mashona) breeds that are inherited by the calf. This observation was made on LR Dahga as young calf.

A set of photos of the dams appears below. Each of these cows was born on Lukefahr ranch and has calved every year in the spring since the age of two years and without any pampering. Excluded as management practices, this year again cattle have neither been dewormed nor treated for external parasites. To date this year (August 15) the total feed cost per cow is under $10.00.

For  2018, the average birth weight of all the calves was 72.2 pounds. In recent years, Star cattle have become shorter-framed, lighter at birth and at maturity (improving cow efficiency), deeper bodied and more muscular, as well as being slick coated and lighter colored. In 2018, most bull calves were born slick while only a few are hairy. The hairy bulls will do just fine above the Texas border where freezing winter storms are common. They will shed their hairy coats by early spring and then express the many genes that they possess for heat tolerance and adaptation to drought conditions, which they will transmit to their offspring. However, breeders that have purchased Star bulls who are from AR, MO, NC, NM, OK, and WY have confidently claimed no problems with their slick cattle during winter. Slick cattle typically produce a short hairy coat in the winter, but this coat is quickly shed in early spring as shown in the following photo taken in winter of a slick Star bull in Arkansas.

Annually, DNA tests performed by GeneSeek to reveal which calves are homozygous (two genes) versus heterozygous (one gene) for the slick trait. This means that later as parents those bulls that are homozygous will breed true for this trait – all of their offspring will be slick and express even greater heat tolerance. Bulls that are heterozygous (one gene) are expected to produce the slick trait in half of their calves. Over 10 years of data from calves born on Lukefahr Ranch were recently analyzed, which revealed that slick compared to hairy calves are, on average, 35 pounds heavier at weaning age (205-day adjusted). This is a dramatic effect of only one very major gene!



Lukefahr Ranch sells genetically heat-tolerant and drought-adapted cattle by offering grass developed young bulls on a first-come, first-served basis. Over several generations, an easy-care cattle herd has been developed. For ranchers that have been affected by serious drought, this is an excellent opportunity for you to invest in a young bull or bulls from this STAR composite herd that can help you rebuild your herds with the right, easy-care genetics for a low-input system by working closer with Nature. In 2018, most bulls were born in May and will be ready to breed by next summer (recommended mid-July through August) at about 14-1/2 to 15 months of age. Lukefahr Ranch and a growing number of clients have been using such young bulls (either in single-sire pastures or as a cohort of young bulls in multi-sire pastures) for several years now with excellent pregnancy results, which mirror the high fertility test scores via Breeding Soundness Evaluation prior to bull turn-out. The photo below exemplifies the high libido level of 7 month-old bulls.


STAR cattle have low input or maintenance requirements (for the past several years, total annual costs per cow have been under or near $300) even during years of exceptional drought. From 2013 through 2018, total feed costs per cow were under $20. Bull calves offered for sale are from cows that consume during winter mostly stockpiled grass from the fall (without energy or protein supplements) and conceive during their first heat cycle when exposed to a bull between mid-July through August during high heat index conditions.

In past years, our ranch has had good success in selling young, backgrounded bull calves to area ranchers in several states. Because of the high demand, we have not had to retain these calves to breeding age. A STAR bull in one generation will produce daughters with genetics for unsurpassed heat tolerance and drought adaptation. This is a wiser investment than buying STAR heifers. Previous customers (see Bull Owner Success Stories from the menu area) have been especially pleased when using STAR composite bulls (in the form of corrective matings) on Beefmaster, Brangus and Santa Gertrudis purebred and crossbred type cows. The female offspring develop into mature cows with considerably smaller frame and moderate body size, and are not excessive in flesh, bone or milk production in addition to being heat tolerant and drought adapted.

Upon request, each bull is provided with a brief description, a photo, pedigree, and trait EPDs and accuracy values. The genetic evaluations are performed by geneticist and ranch owner, Steven Lukefahr. Trait EPDs are computed for birth and weaning weights, milk, and total maternal. Records are entirely from STAR cattle, as well as pedigree data that trace back to related purebred foundation ancestors. EPD values are all relative to animals with trait records in this unique population. However, EPDs should be used with caution. I would prefer retaining and selling calves with zero or even negative EPDs as such values would likely be associated with lighter calves and smaller and more efficient cows. Of course, negative birth weight EPDs are important if a bull is to be mated to heifers.

In promoting bulls, a photo and information on the bull calf’s dam are also provided. The cows all have great dispositions in addition to good fleshing ability, slick hair coats, high level of fly resistance, and early puberty (usually at 6-7 months of age). The bull calves have early sex drive or libido – as is evident in the above banner photo when these calves were only about 5 months old. Early age at puberty is a trait trademark of STAR cattle which is a show of high fertility and adaptation to the harsh environment without any pampering.

Feel free to contact me by email (slukefahr@gmail.com) or by cell phone (361-219-0382) if you have any questions or if you request additional information on these bulls. This year I have already sold my surplus heifer calves for breeding. I do not have any heifers or cows for sale at this time. Contact me to schedule a personal tour!
