Update: December 31, 2018. As the year closes the following is a summary of performance and profitability results of the Star cattle herd. Pregnancy and weaning rates were 95.1 and 97.2%. Total costs per cow averaged $331 with land lease costs being the largest expenditure at $100 per cow. Total feed costs averaged only $10 per cow (excluding minerals). Average 205-day adjusted weaning weight was 556 pounds. Ultimately, these figures relate to a yield of 64 pounds of beef per acre. Profit per cow was $449 and profit per acre was $58. These profit figures are conservatively based on local market prices at an average of $780 per calf (most calves were actually sold for higher prices as breeding animals). In addition, these performance and profitability results were achieved by the use of genetically-adapted, moderately-sized (approx. average weight of 1,100 pounds), and highly fertile cows on healthy pastures. In 2018, the stocking rate was 7.75 acres per animal unit. This stocking rate was also pivotal in improving land efficiency in terms of pounds of beef produced per acre. Below is a figure that shows how stocking rate (number of acres per cow) has improved since 2014 at a rate of about 2 fewer acres per animal unit per year (through improved carrying capacity of pastures and likely smaller cows). Pounds of beef produced per acre has also improved at a rate of an increase of 6.7 pounds per year.
December 9, 2018. Nearly all of the calves presold a few months ago have been picked up. Half of the breeding calves purchased were from repeat clients who continue to upgrade their herds to a purebred Star base. Some of these repeat clients purchased bull calves that were Mashona-sired – to boost the performance level in their herds due to African genetics for fertility and adaptability and added heterosis. The photo below shows a trailer that was loaded with 2 bulls and 5 heifers destined for Oklahoma. Two ranchers: Kim Barker and Evan Rowland, previously total strangers, made the long trip together. Overall, it was good to see old friends again and to make new ones. Some brought their spouses and children along to see Star cattle in south Texas. Cattle ranchers are indeed the salt of the earth!
May 15, 2018. For 2018, the cow pregnancy rate was 95.1%. Despite brutally high temperature and humidity levels during the breeding season (mid-July through August), over 90% of cows also conceived in their first heat cycle. Cows at Lukefahr Ranch are not pampered; if they do not adapt they are culled. The feed cost per cow in 2017 averaged $4.04. Below is a photo of a Star cow (5/8 Red Angus, 1/8 Senepol, and 1/4 Tuli) with a Mashona-sired heifer calf that weighed 63 pounds.
However, this schedule requires that bulls and cows breed in late summer. This is a challenge for cattle producers in south Texas. This challenge is overcome by use of heat tolerant breeds: Senepol and Tuli. Semen evaluation tests in late June and early July have confirmed high fertility levels in bulls (most bulls tested to date have had over 90% live sperm counts in collections of semen that is highly sperm concentrated). Below is a chart that depicts well the tropical-like conditions during a rather typical breeding season (mid-July through August) in 2014. On most days, temperatures were above 100 F and humidity levels were mostly between 90 and 100%, while wind speed tended to be steady over the breeding season in terms of maximum 10 second wind gusts.
In the above photo, a 4 year-old bull (1/2 Senepol, 1/4 Tuli, and 1/4 Red Angus) serviced four cows in the afternoon on 28 July, 2011, when it was 100 degrees F. Notice too the early interest or libido of seven bull calves! Also notice the good cow body condition of the two cows. Although it was a severe drought year, cows were not being supplemented but were consuming only stockpiled forage.
The above model was developed by Steven Lukefahr after nearly 20 years of experience in aligning cattle genetics with natural cycles through drought management. The model displays the focus on drought management and appropriate genetics in working with natural cycles in south Texas. While the model is self-explanatory, it emphasizes that drought management and genetics is critical for production success in the region. The unique model has been described in detail in articles and in presentations delivered by Lukefahr to beef cattle producers at clinics and other educational events. It is highly ironic that the same model is strikingly similar to one reflected by Nature over the millennia involving wildlife species such as bison and deer. To quote Mr. Tom Lasater: ” Nature is smarter than all of us”! To illustrate, the photo below is of my neighbor’s bison herd which is never supplemented or pampered or given dewormers or vaccines. They winter their calves and later wean them in the early spring about 2 months before they calve again, which they typically do annually for some 20 or more years. Calves only weigh between about 40 and 50 pounds at birth. In addition, cows are very protective of their calves.This is the epitome of easy-care livestock. However, one negative is that they are difficult and dangerous to work in pens. The photo was taken by horseback by Steven Lukefahr, prior to being run out of the pasture by the old cow who is the matriarchal leader!
The figure below presents an overview of my basic ranch management program and below this figure is a table that compares traditional to alternative management practices with the latter being adopted at Lukefahr Ranch.
Guard donkeys – Below is a photo of the spring guardian of young calves in the herd. “Jenny” is shown below with her new foal born on March 12, 2010. Allowing a donkey to foal every few years further stimulates strong maternal behaviors. Jenny often stands guard over cows as they calve, serves as babysitter while cows go off to graze, but especially becomes very active in chasing coyotes and dogs out of pastures! Jenny is not treated as a pet but is managed as any cow in the herd. In 2013 and 2014, her daughter, Jezebel, following two years of training by her dam, is now the guardian of a separate cow herd (middle photo). In April 2017 another jenny was purchased as shown in the right photo. “Molly” is the guardian of another cow herd. Here is a link of an article that appeared in The Cattleman magazine: Guard donkeys.
