(Tarzan). grade 9 electricity formulas He was used for several years in the Pharo Cattle Company breeding program. I have been very pleased by his ability to maintain good body condition (“mud fat”) and settle all cows that he has been exposed to thus far. The breeding objective of Lukefahr Ranch is to maintain a herd of polled, slick and light-colored STAR cattle of appropriate tropical genetics for the region where selection is applied to promote high fertility and survival in a low input system while working closely with Nature. While a great bull, Tarzan does have a few issues. He is dark red and horned, and he attracts a lot of flies (likely due to his high testosterone level and darker coat color). Fortunately, several of his sons out of Star cows are polled, slick-coated, and light-colored. Below is a photo of Tarzan and one of his sons as a 2 month-old calf who will be saved as a breeding herd bull replacement. The dam of this bull calf is Tuli-sired (Honey Bear), and her dam was Red Angus-sired (Leachman’s Bandito Tres), and her dam was Senepol-sired (Nocona). Besides having a great pedigree, his projected level of tropical genetics is 84.4%. As a composite-bred animal he should express a very high level of heterosis.

Since the Star population is an open herd, several purebred AI bulls (Red Angus, Senepol, and Tuli) with negative birth weight EPDs have been used to decrease average birth weights. Photos of the most influential bulls are shown at the bottom of the figure with their birth weight EPDs. On the right side of the figure are photos of several of the most influential Star bulls that were born on Lukefahr Ranch that tend to have even larger negative EPDs for birth weight than most of the purebred AI bulls. Even though each of these Star bulls are related to two or more of the featured AI bulls, through gene recombination it is possible to produce composite-bred calves that inherit genes from AI bulls for all three breeds that will produce even lighter calves at birth. Other unrelated AI bulls have also been used, for example Above and Beyond and Schuler Rebel (Red Angus bulls) and WC 950K (a Senepol bull) to further reduce birth weights, while expanding the gene pool to minimize inbreeding but optimize hybrid vigor. Selection for the slick gene from Senepol and genes for light color, among other traits related to heat tolerance, has also occurred. This figure may serve as the basis for a future article. electricity pictures information Stay posted.

One unfair advantage of being located in deep south Texas is an early spring. Calves that were wintered on their dams were recently weaned at 10 months of age. In most cases, their dams had already weaned them for me. This past winter was unusual. Several cold fronts resulted in freezing temperatures and one blizzard even resulted in over 6 inches of snow! Although I had stockpiled forage in all the pastures last fall in preparation for winter grazing, the freezing temps did damage the grass and reduced the forage quality. In a couple of herds where cows were wintering heifer calves (most bull calves had already been weaned and sold for breeding), I did decide to feed range cubes in order to keep cows’ body condition at a minimum score of 5 while still raising their calves. Although range cubes were fed, since January 1 the total feed costs averaged only $6.12 per cow. Also, no hay was fed. About one month ago I stopped feeding cubes when there was enough green grass and forbs to meet the cow’s protein needs. Below is a photo of wintered heifers taken in early January which shows the low quality forage. The other photo was taken on March 5 of a cow that had wintered her heifer. 10 gases and their uses Cows now have 2 months of grazing green grass before they calve in May.

Some readers my find the set of graphs particularly interesting, which were updated after closing the books on 2017. The first one involves trend for total costs per cow, which have dramatically decreased through better grazing management and by utilizing more adaptable genetics. The second graph shows stocking rate (SR) trend over the past 17 years. Hay has not been fed for over 16 years. The graph speaks volumes about drought management and management in general. First, between 2001 and 2004, the ranch was transitioning between traditional overstocking and continuous grazing towards an implemented rotational grazing system. gas oil The initial key decision was made in 2001 to reduce SR (more acres per cow). Because of the adverse effects of past poor grazing management, a few years were required for pasture health to recover. After 2004, pastures were in better condition (quality and quantity) so SR was increased (fewer acres per cow). Then starting in 2009 were years of extreme to exceptional drought. In 2013, SR was reduced (i.e., more acres per cow) to be more conservative on forage resources – mostly achieved by moving cows to temporary leases and selling 20% of the cow herd (mostly older cows and cows that made too much milk). In late 2014 and throughout 2015, ample rains returned and pastures gradually began to recover. In response, in 2015 the SR was increased from 16.0 to 12.2 acres per cow and in 2017 stood at 9.1 acres per cow. What is perhaps most interesting over these years is that as SR has been reduced (more acres per cow) the pounds of beef in weaned calves and profit per acre (last two graphs) have both generally increased in more recent years following a drought management plan and having adaptable cattle which continue to improve in performance.

RANCH MANAGEMENT at Lukefahr Ranch reflects the paradigm of ‘Working with Nature’ as illustrated in the following figure. Calves are born mostly in May (see figure below). The green line depicts forage quality whereas the red line represents cow’s nutritional requirements. i feel electricity in my body Working closely with Nature allows cows to gain flesh condition prior to calving from the spring flush of green grass. Especially for heifers, this will ensure high herd fertility or breed-back.

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). gas vs electric stove safety 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. electricity production in north korea 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!

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). electricity production by source 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 .

On 17 November, weights at weaning age were recorded for the 2018 calf crop. The oldest Star cow is LR Beth who was born in 2003. She is half Red Angus and half Senepol. (In 2005 the first three-breed composites would be born.) Being fully crossbred, Beth has displayed considerable heterosis for reproductive- and disease resistance-traits over her entire lifetime. Below is a photo of LR Beth. She has weaned a good calf every year for 14 years without any pampering (in most years the total cost per cow averages about $300), and has produced nearly 4 tons of beef in weaned calves.

In addition, the heaviest calf that was Mashona-sired had a 205-day adjusted weaning weight of 658.5 lbs (photo below taken 2-1/2 months ago). His dam (LR Chiffon) is 11 years old and is one-half Tuli, one-quarter Red Angus, and one-quarter Senepol. The selection of bull calves as replacements will take the genetics of the herd to another level in terms of genetic adaptability in hot climates and without pampering that translates into cow longevity.
