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...

SPRING WEATHER CONDITIONS CREATE A CHALLENGE FOR FORAGES
A cool, wet spring delayed growth of several summer grasses, but not the weeds that compete for space in fields and pastures across Mississippi.
IT'S THE PITTS -- UNIDENTIFIED FRUITY OBJECT
Besides being a great-granddaughter of the former President, Laura Eisenhower is a professional clairvoyant and spiritual healer who reads Tarot cards and gives astrology readings for a living. In an interview with Fox News Laura said that vegetarians are more apt to see UFO's than meat-eaters because, "we are multidimensional beings and based on our frequency, perceptions and our vibratory levels that we are functioning from, we are going to see things differently."
PRODUCERS SHOULD EVALUATE VALUE OF CREEP FEEDING
n the last issue we started a discussion concerning creep feeding and an ongoing evaluation of the value of this practice in cow-calf production. The main question the producer has to ask is “if I decide to creep feed my calves will this result in higher weaning weights and will it be profitable?”
THE WORLD ACCORDING TO HOOTER MCCORMICK -- WINDSHIELD ECONOMICS
Hooter was riding shotgun with Peetie Womack on the way back home from a feedlot where Peetie was checking on some of his cattle.
GENETRUST AT SUHN CATTLE COMPANY BULLS AVERAGE $5,863
Blue skies, blustery winds and Brangus bulls welcomed customers and friends of GENETRUST to the Flint Hills in Eureka, Kansas, on March 22, 2016 for the 24th annual installment of the event hosted by the Suhn family, in what has become one of the premier Brangus events of the year.
BLACK INK -- BEYOND THE BURNING HAIR
Our electric branding iron hangs high on a barn wall, bought on impulse 35 years ago but not used in 30. We freeze brand our replacement heifers though.
IT'S THE PITTS -- MOTHER NATURE, FATHER TIME
Women are nature, men are time. Women are beautiful like a Maui sunset or a forest of pine wearing a fresh blanket of snow, while men are as timeless as Shakespeare, Michelangelo and Da Vinci.
GRASS-FED BEEF CONFERENCE TO BE HELD MAY 26-27, 2016
With consumer interest heightening about where their food comes from, grass-fed beef producers will have the opportunity to learn more about marketing opportunities and production trends during a May 26-27 conference in College Station.
HUNTIN' DAYLIGHT - DECLINING PRICES MAGNIFY COST FOCUS
“Expenses won't come down as fast as commodity prices,” says Stan Bevers, Texas A&M AgriLife Extension Service economist. “Cow-calf expenses won't come down as fast as cow-calf prices. 2016 will have lower calf prices but not to the extent it will affect these higher expenses. During 2017, expenses still will not be coming down, where calf prices will be in their second year of decline. That's what concerns me.”
CONSIDER PROS AND CONS BEFORE CREEP FEEDING
Creep feeding of calves while still on the cow has been a management tool used for years by the cow-calf producer. The value and profitability of this practice has been long debated as well. So when producers ask if it is something worth considering, I give them the stock nutritionist's answer: “well, it depends.”
LITTLE W CHAROLAIS HOLDS PRODUCTION SALE
Little W Charolais held their 6th annual production sale on March 26, 2016 at the farm in Lebanon, Tenn.
EGYPTIAN VET STUDIES AT MISSISSIPPI STATE
New research techniques learned at Mississippi State University through a scholar exchange program will help a cattle veterinarian from Egypt as she pursues a doctoral education in food safety.
DEER ANTLERS MAY HOLD HEALTH SECRETS
Each spring the woods are littered with antlers as deer shed their old racks to make way for new sets, and these “sheds” may reveal hidden health problems in the bucks that drop them.
CLEMSON EXTENSION OFFERS CATTLEMEN'S BOOT CAMP
Gaven and April Hammett want to expand their cattle operation and are looking to Clemson University for the information they need.
EARLY SPRING CAN BE A CHALLENGING NUTRITIONAL TIME FOR SPRING CALVING
Late winter and early spring is the most challenging time of the year for the nutrition of the spring-calving beef cows.
