Crossbreeding offers two primary advantages: heterosis (also called hybrid vigor) and the opportunity for breed complementarity. When the performance of crossbred offspring exceeds the performance of the purebred parents, the difference is called heterosis. In other words, the whole can be greater than the sum of the parts. For instance, if straightbred Hereford and Angus calves average 500 pounds at weaning and Hereford x Angus calves average 525 pounds, the heterosis realized is (525-500)/500, or 5 percent. Maximizing Heterosis Realization of heterosis is the closest thing to a free lunch that can be found in the cattle business. Thus, all commercial beef cattle producers should seek to maximize heterosis in their herds. Some crossbreeding systems offer a greater degree of heterosis than others, and some traits respond more to crossbreeding than others. Heterosis is realized in inverse proportion to heritability for a given trait. In other words, lowly heritable traits offer the most heterosis, highly heritable traits the least. Table 1 lists beef cattle traits of economic importance and their heritability estimates. In general, reproductive traits are lowly heritable, growth traits are moderate and carcass traits are highly heritable. Thus, differences in reproductive performance between herds are virtually all due to environment and management, while differences in growth or carcass traits are due primarily to genetics. Also, reproductive traits will respond the most to crossbreeding, carcass traits the least. Read more...

RIGOROUS CULLING HELPS MAINTAIN EFFICIENT HERD
Which cows in your herd are making you money and who is losing you money? Every year, the cow-calf producer needs to critically evaluate each animal in the herd and decide if she is paying her upkeep
NOT TOO EARLY TO START "HEAT STRESS" DISCUSSION
A couple of weeks ago, here in Texas as well as numerous other locations across the US, temperatures bumped up into the 70's and even the 80's in some areas. This was in FEBRUARY! Granted, it has cooled back down but nonetheless it's already gotten warm in lots of locales across the country and will again very soon. That in mind, it's not too early to start the “heat stress” discussion and how this can affect animal performance. Heat stress is a major contributor to animal and production losses each year.
RESEARCH LAUNCHED TO IMPROVE BEEF SUSTAINABILITY
Environmental, social and economic sustainability is a long-held objective of the United States beef industry and the focus of a new, national research project.
BULL MANAGEMENT IS A KEY TO SUCCESSFUL BREEDING SEASONS
Bull management before and during breeding season can improve producers' chances for reproductive success, said a Texas A&M AgriLife Extension Service expert.
RESEARCH TRIALS FOCUS ON WINTER PASTURE STOCKING
Profits in stocker production can be as green as winter pastures when conditions are right and producers apply correct stocking strategies, according to a Texas A&M AgriLife Research expert.
IT'S THE PITTS -- SHE SAID WHAT?
I remember learning early in life that humans should use all five of their senses, but darn it, mine don't work anymore.
INTERNAL PARASITE CONTROL SAVES PRODUCERS SIGNIFICANTLY EVERY YEAR
Since man has managed and produced cattle, control of internal parasites (worms, flukes) has been an issue. And while the industry seems to repeatedly discuss and address the problem, given the implications on animal health and performance, revisiting the subject is a necessity.
HUNTIN' DAYLIGHT -- WHERE THE COWS ARE
Whether you're looking to buy or sell calves, feeders, breeding cows or bulls, it's always worth pondering the relative volume of inventory and where it exists.
FORAGE AND RUMINANT LAB HELPS RESEARCHERS
The Forage and Ruminant Nutrition Lab at the Texas A&M AgriLife Research and Extension Center in Stephenville explores ways to improve ruminant diets and mitigate negative environmental impacts for researchers around the state, nation and globe, according to a Texas A&M AgriLife Research expert.
BEEF EXPORTS INCREASE U.S. CARCASS VALUES
Mouthwatering steaks, juicy burgers and delectable roasts. That's what consumers here in the U.S. love. But what about the underutilized parts of the beef animal? If we don't consume them here in the U.S., where do they go, and who uses them?
CERTIFIED ANGUS BEEF STUDY SHOWS MARBLING STILL MATTERS
Just missed it. Just missing a flight, a deadline for a major rebate, or watching your child's winning shot at a ball game. The feeling is much the same.
BULL IS BEEF HERD'S ULTIMATE ATHLETE
LeBron James. Tom Brady. Usain Bolt. These names bring with them a certain performance standard. Each season, fans expect these athletes to be in top form, to perform and to achieve results no one else is capable of. You expect the same of your breeding bulls each season, but are you treating them like the athletes that they are?
GENETRUST AT CAVENDER'S SALE AVERAGES $5,038
A tremendous crowd gathered at Cavender's Neches River Ranch to appraise the largest Brangus and Ultrablack bull sale in the state of Texas on November 19, 2016 and based upon the demand throughout the day, they liked what they saw.
THE WORLD ACCORDING TO HOOTER MCCORMICK -- DIFFERENT STRIPES
Hooter was feeling lucky. He bought the set of calves because they were cheap enough, and he had some wheat pasture for them. But being able to sell them into an up market with solid gain as the grazing ran thin was more chance than plan. He knew that, but he also couldn't help feeling just a tiny bit proud.
A.I. CAN CATAPULT BEEF BREEDING PROGRAMS FORWARD
The first use of artificial insemination was accomplished by Arab Sheiks who wanted to utilize bloodlines of tribal enemies. They would sneak up to the other tribe's herd at night with a mare in heat secretly collect semen from the stallion into a leather pouch and take it back to their own camp to inseminate a prize mare.
