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...

MARKETING CATTLE AT PROPER TIME IS KEY TO PROFITS
Marketing cattle efficiently and at the proper time can make money for the producer. There are many costs involved in getting cattle to market and it is important to try to minimize those costs. Many cattle producers do a good job of getting the calves born, keeping them healthy, minimizing sickness and death loss, but only do an average or even a poor job of marketing those calves and thus reduce their potential profit.

PRODUCERS FIND SUCCESS GRAZING COVER CROPS
Interest in planting cover crops on Mississippi row crop acres continues to grow, along with interest in adding livestock grazing on those acres. Cover crops have been used by growers of cash crops for many years to solve a number of problems. Erosion, water quality, nutrient loss, compaction, organic matter, and conversion to no-till planting have all been addressed by the use of cover crops
REMOTE DRUG DELIVERY SYSTEMS AREA GAINING POPULARITY
Remote drug delivery (RDD) systems, or dart guns, are being used more and more frequently throughout the beef industry for the delivery of antibiotics.
KNOWLEDGE OF GRAZING BEHAVIOR CAN AID MANAGEMENT
As ruminants, cattle can eat a lot of forage in a short time. Understanding and taking grazing behavior into account can help stockmen optimize production when managing cattle on pastures.
MANAGE FORAGES IN ANTICIPATION OF NEXT DROUGHT
A few years ago we were in the midst of one of the worst droughts in US history. It had huge implications on the beef cattle producer as well as most of production agriculture. Fortunately, these conditions passed, moisture conditions improved in most areas and we were back to “normal.”
IT'S THE PITTS -- MY MOST MEMORABLE VACATIONS
It's summer and many Americans are on vacation. But not my wife and I.
HUNTIN' DAYLIGHT -- INDEXING OPPORTUNITIES
“Selection indices, to me, are the most valuable tool we have to help us make more right decisions and fewer mistakes,” says Donnell Brown of R.A. Brown Ranch at Throckmorton, Texas.
