Dr. Zinn grew up in Southern New York and received his BS in Animal Science from Cornell University. He then worked as the Research Coordinator at the Cornell Dairy Teaching and Research Unit for 2.5 years. After that, he then received his MS and PhD degrees in Animal Science from Michigan State University. Following completion of a post doc at the Worcester Foundation for Experimental Biology, he joined the faculty of Animal Science at the University of Connecticut in 1990.
Area of Interest
My research interests are tissue-specific expression of growth factors during development in livestock and physiological mechanisms involved in efficiency of animal production. This work focuses primarily on the role of endocrine and other metabolic factors in the growth process.
Our current work focuses on the effects of maternal feeding on the development of the offspring in sheep. Under- or over-feeding the dam during pregnancy can have long-lasting detrimental effects on the offspring that can impact overall health, growth rate, efficiency and the amount of protein and fat in the carcass. We are currently investigating the multi-generational effect of poor maternal nutrition and its impact on the feed efficiency of the offspring.
