Modern grass cattle concepts

Cattle genetics have changed and backgrounders may need to react.

Frank Brazle, retired Kansas State University Extension beef specialist, has studied the stocker industry for more than 30 years.

“There used to be just acres and acres of light-weight cattle, and they had to be backgrounded,” he says. “The cows didn’t milk as well and the calves didn’t have the growth.”

Now most of those lighter calves are specific to the “fescue belt”—from southeast Kansas to the southern Appalachians—where endophyte fungus can retard milk production. Otherwise, calves are coming off the cow weighing more than ever before, says Brazle.

Cattle Preconditioning Forum: Treating Respiratory Disease

Cattle Preconditioning Forum: Treating Respiratory Disease

Develop a plan for treating sick animals before they get sick. It is important to get your veterinarian involved before the cattle arrive. This involves setting criteria for which animals will be treated for illness, what animal health products will be used, for how long and how many products will be tried before the animal is considered a “chronic.”

At the U of A, the criteria used for treatment are a rectal body temperature of 104° Fahrenheit or greater, depression, loss of appetite, discharge from the eyes and nose, difficult breathing and coughing. Many animals will not show all of these symptoms.

Learning to recognize sick animals is an art. When animals are pulled sick, one antibiotic is tried initially for the prescribed dose and time. The animal is rechecked in 24 to 48 hours. If the antibiotic does not appear to be working, another is used. After a third treatment, the animal is on its own. If these animals die, there will be so much lung damage that the animal had no chance of recovering.

Beef Tenderness — Genetics And Management

Beef Tenderness — Genetics And Management

By Troy Marshall

Beef magazine

A checkoff-funded study on beef tenderness provided some carcass insights between steers and heifers. Authored by Colorado State University’s Darryl Tatum, the study showed that, despite heifers tending to have higher quality grades than steers, they’re consistently tougher, have a much higher percentage of undesirable eating experiences due to tenderness, and produce a significantly higher number of dark cutters.

The report recommends longer aging periods for heifers (21 days), and more caution in their handling in order to reduce pre-harvest stress.

Hormonal effects are also believed to be a contributing factor to the heifer tenderness issue. Spaying of heifers and MGA feeding (MGA should not be removed from heifers more than 24 hours pre-harvest), and not using aggressive implant procedures were some of the tactics suggested to improve tenderness in heifers. Longer aging also tends to mitigate the effects of aggressive implant procedures on tenderness.

Cattle need to grow fast and efficiently convert feed into kind of beef consumers want for them to make a profit in feedlot. That’s not as difficult as some people think, but takes a balanced approach. Research shows you don’t have choose between carcass merit and performance planning for maximum profit.

Targeted Grazing

 

Targeted Grazing

Angus Journal

There’s a new movement gaining momentum among rangeland managers. It’s called targeted grazing, and it has the potential to help combat invasive weeds, reduce fuel loads for fire risk, and restore rangelands and forests.

Obviously there’s nothing new about livestock grazing, but Karen Launchbaugh, chair of the University of Idaho’s Rangeland Ecology Department, says, “We are using grazing in a new way that offers an ecologically friendly aspect to help restore landscapes.

A NEW research project aims to boost productivity in the livestock industry by creating more nutritional and higher-quality pastures.

The research focuses on the discovery of genetic markers in perennial ryegrass and white clover.

The Molecular Plant Breeding Co-operative Research Centre has received an extra $6 million for the research, bringing investment in the project to $11 million.
