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...

CONTROL FLIES TO AVOID PINKEYE PROBLEMS
We were fortunate this year to have quite a mild winter in the southeast. The grass is growing and we are getting some much-needed rain to fill the ponds that dried up during last year's drought. Unfortunately, along with warmer weather come the flies and various problems associated with the little pests. Severe fly infestations have been associated with increased incidence of pinkeye, or infectious bovine keratoconjunctivitis (IBK).
CIRCLE A ANGUS RANCH SALE HELD MARCH 18
Circle A Angus Ranch, headquartered in Iberia, Mo., was proud to host their 23rd Annual Spring Bull And Heifer Sale offering 345 head sold on March 18th.
WHY IS INSECTICIDE RESISTANCE AN ISSUE IN HORN FLIES?
What is insecticide resistance? It's the inherited ability of flies to survive an insecticide dose that would kill the majority of flies in a normal population.
SMALL CREATURES MAKE BIG ECOSYSTEM IMPACTS
Many Mississippians care about wildlife and related activities, including hunting, fishing, birdwatching or just enjoying the outdoors.
CONSUMERS HAVE OPTIONS, SO PUT BEST BEEF FORWARD
The growing beef supply won't automatically find more room in the meat case, but it can earn its way with differentiated quality.
NEBRASKA STUDY SHOWS NO ILL EFFECTS FROM CROP RESIDUE GRAZING
It makes sense that a 1,200 pound Angus cow would place quite a lot of pressure on the ground on which it walks. But a new study shows that even these heavy beasts can't do much to compact common soils—if they're grazed responsibly.
IT'S THE PITTS -- ASK THE STYLEMASTER
It's been awhile (30 years) since I, the god of good taste, answered your many questions regarding what's in style. It's quite natural that you'd seek guidance from such a fashion forward expert as myself.
PASTURE RECOVERY AFTER DROUGHT CAN BE DIFFICULT
Maintaining a healthy pasture can be challenging, even in years with average rainfall. Drought affected the southeastern US from July to December of 2016. Drought conditions can impact pasture productivity further into next season.
PRIORITIZATION IS IMPORTANT TO NUTRIENT MANAGEMENT
Most cattle producers have a nutrition program of one type or another. Some are very well structured, perhaps even having been designed working with a nutritionist. Others are less sophisticated and are the results of getting recommendations at the local feed store or coffee shop. Some are very simple and include grazing on pasture, feeding some hay in winter and throwing out some range cubes when you want to call the cows up to gather calves (this is the program I grew up with).
THE WORLD ACCORDING TO HOOTER MCCORMICK -- HOW THEY'RE RAISED
“It was what I would call a life-affirming experience, maybe even a life-altering one,” Peetie Womack said with a solemnity seldom heard. He was addressing the monthly meeting of the Rio Rojo Cattlemen's Association (RRCA), talking about a brief journey to Kansas where recent wildfires had done some of the broadest and worst damage.
DEBTER RECOGNIZED BY ALABAMA BCIA
The Alabama Beef Cattle Improvement Association (BCIA) recently awarded the 2016 Richard Deese Award to Glynn Debter of Debter Hereford Farm in Horton, at the 2017 Alabama BCIA Annual Meeting held in Jemison on March 11.
SALACOA VALLEY BRANGUS SALE HELD MARCH 25
Eighty-nine registered buyers from 11 states and Australia participated in the recent Salacoa Valley Customer Appreciation Sale in at Salacoa Valley Farms in Fairmont, Ga.
IT'S THE PITTS -- MY EMPTY-BUCKET LIST
Other than becoming the first billion dollar lotto winner, my bucket-list is empty. I've already jumped in a pool fully clothed, made soap, worked a potter's wheel and been lost in the smoke at 6,000 feet over Donner Pass in a small airplane.
NUTRITIONAL TOOLS ENHANCE HERD PERFORMANCE
In more recent history, cattle producers are beginning to focus more on production efficiency. “What is the most economical way I can produce a calf or a pound of gain on the bulls and heifers I sell?” With every production parameter there is an efficiency measurement that comes with it. Cattle producers are in a constant search for ways to save money or improve productivity and profits. Producers who are in the business to be profitable and to maximize profits should review all avenues that can improve efficiency and help the productivity and performance of their herds. Since the largest single input for most herds is nutrition this article will focus on this aspect.
HUNTIN' DAYLIGHT -- TRADING UP IN HERD REVENUE
Although still discounted relative to fed cattle, resurgent calf and feeder cattle prices continued to lift hopes through March.
