BeefTalk: The Future of Beef – Midsized Challenges
By Kris Ringwall, Beef Specialist
NDSU Extension Service
There is considerable difficulty in being in the middle because the middle seldom stays the middle. The middle (average) is where no one wants to stay. For most, our upbringing has been to move away from the middle and strive to excel, dominate and extend whatever it is that we do to further heights.
The consequence of this business approach has affected rural areas in many ways. One major effect has been the lack of neighbors. In cattle country, the lack of neighbors translates into the lack of help. This is not a new concept, but it is a concept that has been with us since people have been engaged in business.
This gradual elimination of the players or partners in the beef business is part of a cycle that (hopefully) will perhaps someday recycle and redistribute resources. For the time being, the future of the cattle business seems to be pointed to larger and more expansive operations.
Provide Good Nutrition for Weaned or Purchased Bulls
Probably the most common mistake made in purchasing young, weaning age bulls is failure to provide an adequate diet to continue their growth and development. Often bulls are delivered, turned out with the other bulls, and let to “rough it” until breeding time. Thus, bull development is delayed, sexual maturity is not achieved, and the resulting calf crop is less than it should have been.
The first step in providing adequate nutrition is determining the desired level of performance. Typically, young bulls have 160 days to grow from weaning to yearling age. Because of the growth potential of our current beef population, yearling bulls are heavier than 1,000 pounds. Therefore, young bulls need to have gains of 2.5 daily. Moderate energy diets (those with grain) are needed to attain these performance levels.
Cattle: Tetany Problems in Beef Cows
Many beef producers are utilizing cereal greenfeed and/or straw as the main forage source for their cattle. During the past couple of years an increasing number of cattle herds have exhibited tetany-like problems. It is becoming apparent that high levels of potassium & low levels of calcium may be present in many of the cereal forages used as the main roughage source for cattle. High levels of potassium and low levels of calcium in the diet can limit the absorption of magnesium, resulting in tetany problems.
Tetany and milk fever are two metabolic diseases that produce tetany-like symptoms. Symptoms include depressed appetite, reduced weight gain, nervousness, staggering, stiff gait, convulsions and paralysis usually in mature cattle. Grass tetany refers to animals that exhibit tetany-like symptoms after being turned out on lush pasture, while winter tetany refers to animals fed on winter rations that exhibit similar symptoms. Tetany is caused by hypomagnesmia, or low blood magnesium (Mg) and milk fever is caused by hypocalcemica or low blood calcium (Ca). Symptoms of both conditions are often seen in mature cows in late pregnancy (about 6 weeks before calving) or soon after calving.
Prop. 204 an attempt to regulate Arizona’s factory farms
By HOWARD FISCHER

PHOENIX — Jim Klinker admitted that the biggest hurdle for foes of Proposition 204 is that most Arizonans have never been on a farm — and have no real idea of where the food comes from that reaches their tables.
In fact, the executive secretary of the Arizona Farm Bureau Federation conceded, just the reverse may be true: People imagine that the animals that they know have been slaughtered to make that pork and bacon have lived out their lives frolicking in the grass and wallowing in the mud.
KSU: Cows may need high-concentrate diets this winter
MANHATTAN, Kan. — After this summer’s drought, many cattle producers have had to start feeding hay earlier and, with the recent hay shortage, have had trouble finding enough to last all winter.
Producers can, however, successfully winter their cows in drylots on high-concentrate diets and maintain desired body condition scores, said Twig Marston, Kansas State University Research and Extension cow- calf specialist.
Feeding a limited, but high-concentrate diet will require greater monitoring to help avoid problems such as rumen acidosis — a decrease in rumen pH causing diarrhea and decreased feed intake; bloat — a swelling of the rumen that occurs when feed fermentation creates a foamy layer at the top of the rumen, which traps gasses; and founde — an increase in rumen acid production and a decrease in pH, he said.
The amount of forage a cow should consume daily ranges from .5 percent to .75 percent of her body weight. This will equal about 5 percent to 7.5 pounds of dry hay, or 30 to 45 pounds of silage daily.
Korean ban on U.S. beef ends
SEOUL, South Korea — The first shipment of U.S. beef in nearly three years arrived in South Korea today after the country lifted an import ban triggered by fears of mad cow disease, the Agriculture Ministry said.
The meat will undergo thorough quarantine inspections and go on sale after about 15 days, Lee said.
South Korea shut its doors to U.S. beef imports in December 2003 after the first reported U.S. case of mad cow disease. The country was the third-largest foreign market for American beef before the ban.
