Study raises new fears over human toll from mad cow disease
PARIS (AFP) – The final human toll from mad-cow disease could be higher than is conventionally thought because of a potential risk from blood transfusion, a new study says.
Variant Creutzfeldt-Jakob disease (vCJD) was identified 10 years ago as the human form of mad-cow disease, a fatal disorder in which a rogue prion protein called PrPSc proliferates in the brain, turning it spongy.

USDA Report: Cattle-On-Feed Data Shows More Big Placements
Prolonged dry pasture conditions during February meant young cattle continued to move into Southern Plains feedlots instead of going out to pastures, according to Friday’s U.S. Department of Agriculture’s monthly cattle-on-feed report analyses.

Pre-Calving Nutrition Of Dams Influence Reproductive Performance
All of their lives, beef producers have been told: “You can’t starve a profit out of a cow!” Such is the case with pre-calving nutrition of cows. Occasionally, short term cost cutting measures look successful in the short run, but in the long haul they may just backfire.
Acutely Restricting Nutrition Causes Anovulation and Alters Endocrine Function in Beef Heifers

Story in Brief
The effects of acutely restricting nutrition on ovulation and metabolic hormones were evaluated in Angus x Hereford heifers. Heifers were housed in individual pens in a barn and fed a diet supplying 1.2 of their maintenance requirements for protein and energy (1.2 M) for 10 d to allow time to adjust to the environment and diet. Heifers were then fed a diet supplying either .4 of their maintenance requirements (.4 M) or 1.2 M, and heifers were treated with prostaglandin F2a so they would ovulate on d 14 of restriction. If heifers had plasma progesterone less than .5 ng/mL on d 15 to 28, they were classified as anovulatory. Seventy percent (7 of 10) of .4 M heifers did not ovulate on d 14 while all 1.2 M heifers had normal luteal function. Heifers fed .4 M had less plasma thyroxine and increased nonesterified fatty acid (NEFA) concentrations compared with 1.2 M heifers. Nutritional restriction decreased concentrations of insulin-like growth factor-I (IGF-I) in plasma. We conclude that acute nutritional restriction can alter plasma concentrations of NEFA, thyroxine, and IGF-I and induce anovulation in beef heifers.
USDA TO DISPATCH TECHNICAL TEAM TO JAPAN
WASHINGTON, March 22, 2006––Agriculture Secretary Mike Johanns today announced a USDA technical team will meet with Japanese government officials on Tuesday, March 28th and Wednesday, March 29th, to answer questions and press for the reopening of the Japanese market to U.S. beef.
“The United States is eager to provide any additional clarification Japan may request so we can resume beef exports to Japan as quickly as possible,” Johanns said. “I believe our report is thorough and actions address the unique circumstances surrounding this ineligible shipment. Now my hope is that we can take the next steps toward resumption of normal trade.”
