Impact of cow
nutrition on reproduction and calf performance
Recent research reported in the Journal of Animal Science evaluated influence of supplemental protein prepartum and grazing subirrigated meadow postpartum on cow reproductive and calf feedlot performance parameters. A 2x2 factorial arrangements resulted in prepartum treatments of cows receiving 0.45 kg of supplement / day (42% CP) or no supplement. Post partum management (30 days prior to breeding) compared cows grazing a common subirrigated meadow and the remainder fed grass hay in a drylot. Prepartum feeding supplement improved BCS precalving (5.1 vs. 4.7) and prebreeding (5.1 vs. 4.9) and increased the percentage of live calves at weaning (98.5% vs. 93.6%). Calves born to dams supplemented prepartum had higher weaning weights compared to calves from dams with no supplement. Calves from both groups had similar birth weights and feedlot characteristics (DMI, ADG, HCW). Postpartum grazing improved prebreeding BCS, but did not impact pregnancy rate. The grazing also increased weaning weight, but did not significantly change feedlot parameters. The increased percentage of live calves at weaning resulting from supplemental protein prepartum increased net returns at weaning and through the feedlot phase. Grazing subirrigated meadow postpartum improved net returns regardless of whether calves were marketed at weaning or after finishing in feedlot.

Certified Angus Beef changes requirements
Wooster, OH; Sep 12, 2006
Certified Angus Beef (CAB) recently adjusted brand specifications in response to beef industry changes and industry demand. Finished cattle weights have increased steadily and beef fabrication styles have evolved in the 28 years since CAB was founded. The changes will address uniformity issues and in place of a longstanding yield grade limit of 3.9, the brand will use a more specific consistency requirement in the future. The program adopted a ribeye size bracket of 10 to 16 square inches and a carcass weight cap at less than 1,000 pounds. The program will also investigate limits on external fat thickness to refine compositional consistency. More information on CAB products and programs can be found at: www.CABpartners.com
National ID Expo Proceedings
The National Institute for Animal Agriculture recently held a conference regarding the current state of animal identification. Participants discussed the U.S. Department of Agriculture’s National Animal Identification System (NAIS) and projected implementation of this program. Presentations covering a wide variety of issues were made by producers, government officials, veterinarians and representatives of technology companies. The proceedings are available online at:
Beef Export Guidelines for Japan
Export regulations for sending U.S. beef to foreign countries are a frequent topic of discussion. Media reports have described that Japanese retailers and restaurants selling U.S. beef are running short of supplies. Recently South Korea announced it will resume U.S. boneless beef imports from cattle less than 30 months of age. South Korea was the third largest export market (behind Japan and Mexico) before the ban in 2003. The opening of these markets and potential for regaining lost market share also comes with additional requirements to qualify cattle for export to these countries. Specific export verification program requirements for beef going to Japan can be found on the USDA’s website at:
KSU Veterinary Career Opportunities Workshop in November
Kansas State University Colleges of Veterinary Medicine and Business Administration are holding a Veterinary Career Opportunities Workshop on November 3-4, 2006. The goal of this meeting is to help busy, practicing veterinarians find the right person to join their practice as a new associate. Education includes skills related to finding new associates, graduating student expectations, fair benefits packages, and reasonable job descriptions. This meeting is a great chance to learn about recruiting and hiring the new associate. Practitioners will meet and interact with current veterinary students who are interested in mixed animal practice. Upon leaving the Workshop, practitioners will have a professional, printed job description and a wealth of new knowledge to help build their practices. The conference will be in Manhattan, KS and ten hours of continuing education credit will be awarded for attendance.
Veterinary students from Kansas State University will attend a portion of the Workshop. Brief, mock, interviews between the students and practitioners will be conducted to allow both prospective employers and new associates to discuss expectations related to the specific job.
The cost for this Workshop is $300 for pre-registration, which is due by October 10, 2006. Registration fee includes lectures, proceedings, Friday lunch, reception/dinner, breaks, and Saturday breakfast and lunch. Registration after October 10, 2006 is $350. A block of rooms has been reserved at the Clarion Hotel. The cutoff date for reservations is October 10, 2006, and the rate is $71.00 per night + tax. To register, please send your payment to Veterinary Career Opportunities Workshop, Division of Continuing Education, 141 College Courts Bldg., Kansas State University, Manhattan, KS 66506-6015. Please contact Erin Thomas (785-532-4281, firstname.lastname@example.org ) with any questions.
KSU-CVM Farm Animal Expands Faculty
Dr. Matt Miesner recently joined the Farm Animal section in the Kansas State University College of Veterinary Medicine. Dr. Miesner received his DVM from Washington State University in 1999. Dr. Miesner was an associate veterinarian in general private practice in Pasco, Washington before going on to do a residency in Food Animal Medicine and Surgery at The Ohio State University, Columbus, Ohio. After his residency Dr. Miesner remained at The Ohio State University as a clinical instructor and a year later was appointed as an assistant professor. He then joined Kansas State in August 2006. Dr. Miesner’s primary interests include bovine lameness and metabolic diseases of small and large ruminants.
