Several factors affect abortion frequency in U.S. dairy herds
Using Dairy Herd Improvement (DHI) data, U.S. Department of Agriculture Animal Improvement Programs Laboratory (AIPL) researchers examined factors affecting the frequency of dairy cattle abortions.

The abortion rate was highest at 152-175 days of pregnancy. Overall, the abortion frequency was 1.51 percent for the data analyzed. The average abortion rate was highest in the earliest stages of pregnancy and lowest for cows pregnant 224-250 days.

Abortion rates also followed seasonal patterns, with July as the highest month and December the lowest month for reported percent abortions. The six-month period of February through August saw the highest abortion rates and the six-month period of September through January saw a lower rate. Spring and summer may favor the spread of infectious agents that cause abortion in dairy cattle.

Higher milk production cattle groups experienced higher abortion rates across all breeds.

When looking at geographic differences, AIPL researchers found that California had the highest cattle abortion rate and North Dakota had the lowest. California’s abortion rate was 2.2 percent more than North Dakota’s, across all lactations.

2009 Illinois Dairy Days
“Economic Expectations” is the theme for 2009’s Illinois Dairy Days, a program scheduled for nine locations throughout the state in January.

“The dairy business continues to face challenging times,” said Mike Hutjens, University of Illinois Extension dairy specialist. “To help producers make correct management decisions, it is vital to have the latest information at hand. That is the driving idea behind this one-day program – to help producers make the most of their resources and remain a productive part of the dairy industry.”

Topics to be covered include: feeding challenges with today’s milk prices; managing the replacement herd, evaluating economic alternatives, economic implications of cull dairy cattle, impact of technology on the dairy carbon footprint, manure, livestock gross margin for dairy and herd health update.

New congenital defect reported
Holstein Association and the National Association of Animal Breeders urgently need assistance from dairy producers, A.I. companies and veterinarians in identifying calves that appear to be affected by Brachyspina Syndrome. Please contact the Holstein Association or the Veterinary Diagnostics Center, Dr. David Steffen, PhD, University of Nebraska-Lincoln (UNL), telephone 402-472-1434, before destroying the calf. For genetic research purposes, the entire calf, along with a blood sample from the dam of the affected calf, should be sent to the UNL Veterinary Diagnostic Center.

At this time, the specific gene/mutation responsible for this defect has not been identified. Identifying the gene is the ultimate objective. With a gene test, a carrier can be identified with 100 percent accuracy.

The current genetic test relies on looking for a genetic marker that is closely linked to the causative gene. This linkage test has an accuracy of 95 percent. Research is currently being conducted to find the specific causative gene or another marker that is more closely linked to it.

At this time, the Holstein Association has not taken a position of accepting and recording test results. Obtaining additional information relating to this genetic defect and the testing for carriers is a high priority for NAAB and the Holstein Association. The industry will recommend a specific course of action as soon as appropriate information is available.
