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...

BE VIGILANT TO PREVENT HERD HEALTH RISKS
Beef cattle producers should be observant when conducting annual health vaccination protocols on their cattle, according to Texas A&M AgriLife Extension Service experts.
TAKE MEASURES TO PREVENT FOOT PROBLEMS IN HERD
As is common every year about this time, I have been getting calls and emails regarding hoof problems producers are seeing in their cattle. Generally this starts with “I've been having several cases of foot rot over the last few weeks. . . . ,” and the follow up discussion covers potential treatment and prevention.
IT'S THE PITTS -- PROCRASTINATE NOW
Today or not today, that is the question. Will you finally fix the toilet your wife has been nagging you about, or will you man-up, offer up a flimsy excuse and live to plunge another day?
HUNTIN' DAYLIGHT -- FUNDAMENTALS REMAIN STRONG AT MID-YEAR
“There is no guarantee prices will remain this strong, but there is also no information suggesting prices should decline,” says Andrew P. Griffith, agricultural economist at the University of Tennessee in his early-June market comments.
THE WORLD ACCORDING TO HOOTER MCCORMICK -- SQUIRRELED AWAY
Hooter's old friend, Uncas Bingelmeyer was usually more carefree than the owner of a new credit card at a discount store. Today, though, he watched the scenery speed by as if they were approaching doom instead of Tulsa.
PLAN PROPERLY TO MANAGE YEARLING HEIFER BREEDING
Developing and breeding yearling heifers can be equally rewarding and frustrating. The process is too timely and costly to land anywhere short of success. The technology around estrus synchronization continues to evolve and improve. However, the best protocols alone are not enough to create high pregnancy rates. It requires meticulous planning to properly execute the synchronization protocol and nutrition programs. It all matters when fighting for a few percentage points.
WELL-DESIGNED MANAGEMENT SYSTEM REQUIRES PLANNING
Every business has (or should have) a means of measuring and analyzing the various factors that play a role in overall performance and profitability as well as to help in decision making. Cattle operations are no different.
LOOK FOR SIGNS TO REDUCE AND HANDLE HEAT STRESS
Warmer temperatures are quickly approaching, and that means livestock producers should start considering how to help their animals handle the heat.
BLACK INK -- ARE WE THERE YET?
We were bringing a little preschool friend out to our house for the afternoon. She was a town kid and about every three miles, she'd ask, “Are we ALMOST there?”
IT'S THE PITTS -- HOW TO LOAD A HORSE
Here is the correct way to load a horse.
GIVE YOUNG WILDLIFE SPACE TO GROW
Spring is a glorious time of year. Flowers and leaves are not the only signs of new life. Plenty of food and warmer weather make this the perfect time for wildlife to mate and raise their offspring.
BLACK INK -- ARE YOU ON TRACK?
Biology says it takes two years from the day you breed cows till their calves can be harvested for beef or join the breeding herd to calve as two-year-olds. Decisions before, after and during any two-year span can make a big difference.
