This program seeks to improve animal production through research on the relationship between nutrition and immune function, as well as through research on bovine and porcine male reproductive physiology. In KA 301, we investigate a) development of a model of spermatogenesis that will facilitate investigation of the regulation of gene expression, including transcription factors, during male germ cell development, and identify factors that contribute to male infertility, and b) sperm cellular functions that contribute to in vivo fertility in livestock species, especially the correlation between transcription factors and select mRNAs of sperm and male fertility. In KA 302, we investigate the composition and biological
availability of nutrients in feed as they relate to immune function of the organism.

Goals of this Program
  • Improve production of livestock in the Northeast and nation and to develop products and processes that improve health and reproduction of livestock.
Activities
  • Examine the role of nutritional factors on the immune system function in livestock.
  • Investigate cellular and molecular regulation of spermatogenesis and how it relates to in vivo male fertility in livestock.
