Introduction to Beef Research News
Welcome to the first issue of the Beef Research News. The beef business is rapidly evolving and the volume of data about beef production available is increasing exponentially. Finding and utilizing this information to add value to your client’s operations is a true challenge for all practicing veterinarians. The goal of this monthly electronic newsletter is to provide you brief summaries of current research and information that impacts your daily practice. Topics will range from industry issues to brief summaries of recent published literature.

Ceftiofur pre-slaughter withdrawal change

The Food & Drug Administration (FDA) established a new kidney tolerance for ceftiofur impacting all pre-slaughter withdrawal periods for all brands of this antimicrobial. The FDA also approved a new injection site for Excede® (ceftiofur crystalline free acid, Pfizer Animal Health) at the base of the ear which also impacts the pre-harvest withdrawal period. The new withdrawal periods are effective immediately.

Brand Previous
Pre-harvest Withdrawal
Current*
Pre-Harvest Withdrawal Period (d)
Excede® (ceftiofur crystalline free acid) 0 days 13 days
Excenel® RTU (ceftiofur hydrochloride) 2 days 3 days
Naxcel ® (ceftiofur sodium) 0 days 4 days

Food Supply Veterinary Medicine Reports
The Food Supply Veterinary Medicine Coalition commissioned a research program to examine the current and projected future supply and demand for food supply veterinarians. The reports listed below and in the forthcoming July JAVMA provide an executive summary of the research findings. The objective of the first article is to analyze factors that influence students to select specific career paths, and describe potential methods to encourage careers in food supply veterinary medicine. The second article focuses on the frequency and reasons students and current practitioners changed career paths. The authors found that career changes were relatively uncommon among students and long-term employed veterinarians. The surveys also revealed that practitioners engaged in food supply veterinary medicine reported a high degree of job satisfaction. The final article will discuss future demand for food animal practitioners. The series of articles provides insight into the future of the profession by focusing on student, current practitioner, and academic viewpoints.

Infected feed likely cause of Canada mad cow case

VANCOUVER, British Columbia - Officials were cited as saying on Friday that an investigation into Canada's most recent case of mad cow disease has found that contaminated feed was the likely source of the infection and might provide a link to an earlier case.

The Canadian Food Inspection Agency said the specific source of the infection, reported in April, was not found, but it said there was a feed ingredient supplier in common with a case of bovine spongiform encephalopathy that was discovered in a Canadian cow in January.

CFIA was quoted as saying in a press release that, "This potential link suggests that all of Canada's BSE cases fall within the same geographic cluster, which is reflective of feed sourcing, production and distribution patterns."

The April case, Canada's fifth native-born BSE case, involved a nearly six-year-old pure-bred Holstein dairy cow in southwest British Columbia.




Dean Of K-State's College Of Veterinary Medicine Says New Law Will Help Veterinary Students, Kansas Communities

News release prepared by: Sarah Erskine, 785-532-4187, serskine@vet.k-state.edu

MANHATTAN -- A bill approved by the Kansas Legislature and recently signed into law by Kansas Gov. Kathleen Sebelius will benefit veterinary students and rural Kansas communities, according to Ralph Richardson, dean of the College of Veterinary Medicine at Kansas State University.

The law establishes the "Veterinary Training Program for Rural Kansas" at K-State's College of Veterinary Medicine.

The program will provide opportunities and incentives for students pursuing a veterinary medicine degree at K-State to locate their veterinary practice in rural Kansas communities and serve the livestock industry after they graduate, Richardson said.

A maximum of five students can be enrolled in the program each year, starting in their first year of veterinary college. Each student will receive $20,000 a year for up to four years, to cover tuition and training expenses. In turn, the students will practice veterinary medicine full time in any county in Kansas that has a population of 35,000 or less. The amount of loan forgiveness is determined by how much assistance was received. For each $20,000 a student receives, they will be required to spend a year working in the rural community.

"Other states have passed legislation for a debt forgiveness program; but to my knowledge, Kansas is the first state to pass legislation and appropriate funds for this sort of program," Richardson said.

Many reports from the American Veterinary Medical Association and the Association of American Veterinary Medical Colleges cite shortages of large animal veterinarians, Richardson said. Over the last several decades, the demand for companion animal care has increased dramatically. Many graduates would like to practice in a rural setting, however, they often say that the main reason for not pursuing rural practice is an inability to earn an adequate income and service their educational debt. As a result, many new graduates have been attracted to companion animal care rather than livestock-related veterinary medicine, he said.

"K-State is committed to being a leading institution in large animal veterinary care, animal science, biosecurity and food safety. This new law is one part of a larger undertaking to remain at the forefront of this effort," Richardson said.

"We are dedicated to supporting the livestock industry," he said. "We believe that veterinarians create a positive influence on communities of all types, particularly small, rural communities. This act removes educational debt as a stumbling block for those who wish to make their homes in rural Kansas."



Effects of age on body condition and production parameters of multiparous beef cows
J Anim Sci June 2006 Vol 84 pp. 1890-1895

Five years of production data including quarterly BCS were collected on 454 fall-calving multiparous British crossbred cattle to evaluate associations of age with BCS and production parameters. Body condition score was correlated with dam age at all collection points (pre-calving, prebreeding, weaning, and midway through second trimester of pregnancy). At calving, breeding, and mid 2nd stage pregnancy, 3-yr-old cows had the lowest body weight and BCS, and 8-yr-old cows had the greatest. The authors found that the relationship of pregnancy rate with age appears to be correlated with the BCS decrease at breeding in the older cows. Weaning weight (205-d adjusted weaning weight) comparison to dam age revealed that ten-year-old cows weaned lighter calves than younger dams and 3-year-olds weaned calves lighter than 4- and 5- year old cows. This study documents the effects of age on calving interval, birth weight, and weaning weight that are independent of BCS.
