Parsons, Kansas —
The drought of 2012 is pushing livestock producers to think beyond their usual feed sources, but Kansas State University agronomist Stu Duncan urges caution when it comes to using herbicide-treated soybeans for grazing or forage.
“As more folks consider grazing, haying, or ensiling their failed soybeans this year, they should be mindful of restrictions resulting from the herbicides that were used on the crop, whether burndown, pre-plant, pre-emergence or post-emergence,” said Duncan, who is the northeast area crops specialist with K-State Research and Extension.
A list of herbicides and related label statements pertaining to intervals needed between application and grazing, haying or feeding the herbicide-treated soybeans is available in the August 10 K-State Extension Agronomy newsletter, eUpdate: http://www.agron omy.ksu.edu/doc4019.ashx.
“Be sure to follow label restrictions,” Duncan said. “My advice is, if the label says not to use herbicide-treated crops for grazing or forage use, don’t do it.”

Early summer deworming of nursing calves
Five deworming trials were conducted at the Eastern Research Station located near Haskell, Okla., during the 1990’s. Crossbred cows and their Charolais sired calves were sorted by sex of calf, calf age and cow age, then randomly allotted to one of four treatments.

Raising backyard chickens requires basic knowledge
Interest in keeping chickens in the backyard as a source of eggs and meat is on the rise among both urban and suburban dwellers according to Jess Lyons, a small flock specialist with University of Missouri Extension.

Cow slaughter continues above last year
Total beef production for the year to date is down 1.3 percent and total slaughter is down 2.1 percent compared to the same period last year. Both beef production and slaughter have been larger in recent weeks and the year to date total is down less than expected. A significant part of larger than expected total slaughter is the result of increased cow slaughter.

Short-term calf removal

Kan. beef cattle numbers lowest since 1999
The number of beef cattle on Kansas feedlots is at its lowest point in 14 years, thanks to an ongoing drought, and industry officials said some producers could find themselves out of business if this year continues the dry pattern.

First green grass doesn’t meet cattle’s nutrient needs
Turning cow herds out to graze pastures at the first sign of green grass harms forage growth later in the season. But there’s another big reason to wait, says a University of Missouri beef nutritionist.
Cows don’t benefit from early grazing as much as most herd owners believe. -
Breeding soundness of bulls should involve Trich test
One of the most important factors in determining the profitability of a beef herd is the number of calves weaned per cow exposed.

Temperament plays key role in cattle health
U.S. Department of Agriculture (USDA) and university scientists have found that cattle temperament influences how animals should be handled, how they perform and how they respond to disease.

One calving season verses two calving seasons
The beef industry has seen a “down-sizing” due to the drought affecting many cow herds. Much has been written and spoken about the need to “rebuild the cow herd.” When the return of good moisture allows for adequate forage growth and pasture conditions to improve, ranchers may need to self-examine their operations and look at breeding season alternatives that provide greater sustainability moving forward.
