Penn State University
Dr. Erika Ganda is an Assistant professor of Food Animal Microbiomes at the Department of Animal Science at Penn State University. Her research is focused on the application of innovative technologies to investigate animal health and food safety and the development of practices and approaches that can be applied to the agricultural industry. Dr. Ganda is a member of Penn State’s Microbiome Center, Center for Infectious Disease Dynamics, the multistate research project on Antimicrobial Resistance, the Pennsylvania Consortium for Antimicrobial Stewardship, and the American Society for Microbiology.
Dr. Ganda has expertise in translating valuable information gained through microbiome data into the development of novel animal health interventions. She has investigated the effect of third generation cephalosporins in the bovine milk microbiome upon natural (Ganda et al., 2016) or experimental (Ganda et al., 2017) infection with Gram-negative pathogens, and on healthy and mastitic milk microbiomes. Currently, her research group is working on various projects investigating the microbiome of several food-producing animal species. Examples are recently published work on the investigation of heavy-metal exposure on the resistome of dairy cows (Gaeta et al., 2020), comparison of laboratory methods for profiling bird cloacal microbiomes (van Syoc et al., 2021), investigations on the effect of treatment with metformin on the poultry microbiome (van Syoc et al., 2022), and studies comparing bovine gut microbiomes fed different feed additives.

American Association of Bovine Practitioners
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.

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

University of Pennsylvania
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.
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 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.
