K. Fred Gingrich, II, DVM

American Association of Bovine Practitioners


Recruitment and Retention of Cattle Veterinarians – Is This a Fixable Problem?

Food animal veterinarians currently make up less than 10% of the veterinary profession and there is a recognized shortage by USDA of food animal veterinarians in rural America. AABP has also recognized that there is a drop in membership within the first 5 years of practice and a likely reason is loss of cattle veterinarians to small animal practice. This session will identify the challenges of food animal practice and how veterinarians can be a part of the solution to recruiting and retaining food animal veterinarians in their practice.

Fred Gingrich received his Doctor of Veterinary Medicine from The Ohio State University in 1995. He worked in California at a large dairy practice before returning to Ohio as a mixed animal veterinarian and owner of two veterinary practices. His areas of interest in practice included business management, facility design, milk quality and parlor analysis, records analysis, nutrition and antimicrobial stewardship programs. He was a volunteer with AABP, serving on committees and became the President of the organization in 2015. In 2017, he accepted a position within AABP serving as the fourth Executive Director and retired from private practice.

Making Treatment Decisions for Clinical Mastitis: Part 1

Treatment of mastitis accounts for a large proportion of antibiotic usage but not all cows with mastitis will benefit from antibiotic therapy. In this presentation, results of scientific studies that have evaluated outcomes of antibiotic treatment of non-severe mastitis will be reviewed. Characteristics of cows that can be evaluated to identify animals that may benefit from antibiotics will be described and options for handling cows may not benefit from antibiotics will be discussed. Emphasis will be placed on implementation of defined protocols that help ensure appropriate and economically sound decisions about antibiotic usage for treatment of mastitis.

Making Treatment Decisions for Clinical Mastitis: Part 2

Continuation of Part 1 but emphasizing economic and therapeutic outcomes based on selection of drugs and duration of treatment.

Incidence, Treatments and Outcomes of Diseases of Lactating Dairy Cows

Use of antibiotics on farms is a hot topic and there are many misperceptions. Results of a large study comparing disease incidence, treatment and antibiotic usage in adult cows and preweaned calves on 40 large conventional dairy farms in Wisconsin will be presented. Selected outcomes including use of antimicrobials, herd retention and impact of parity will be discussed.

Lameness – Sore Feet Don’t Make Cent$!

Lameness has become an increasingly important problem in cattle over the last 20 years and this is due to many factors. This session will explore the common causes of infectious and non-infectious foot diseases and discuss necessary preventative tools to manage sore feet in dairy cattle.

Importance of and Management of Bovine Colostrum

Calves are born agammaglobulinemic and their capacity to mount an immune response de novo is limited. Therefore, adequate colostrum intake that leads to a successful transfer of passive immunity is critical for disease prevention and their survival. This session will explore the importance of and management of good quality colostrum.

Acidification and Influence of Acidified Bovine Colostrum on the Gastrointestinal Microbiome of Dairy Calves

Acidification of colostrum is an effective tool in colostrum management. There is a paucity of information on what impact if any acidification might have on the gastrointestinal microbiome of young calves. This session will explore the association of feeding calves acidified colostrum and the increased abundance of gastrointestinal Faecalibacterium, a bacterium that is associated with decreased diarrhea and better calf growth.

Dr. Smith began his career at the University of Pennsylvania, in 1998. He has been recognized for his contribution to veterinary science and education by receiving the Lindback Teaching Award, Carl Norden-Pfizer Distinguished Teacher Award, and the Dean’s Award for Leadership in Clinical Science Education.
