Animal Health and Well-Being

Animal health and well-being are crucial building blocks for successful farm operations and a safe, high-quality, and abundant food supply. The Department of Animal Science conducts research projects to improve the health and well-being of beef and dairy cattle, sheep and goats, horses, and poultry. Disease prevention has been a main focus of our research programs. Some research strategies rely on animal behavior or farm management impacts on prevention. Other research focuses on virulence factors of disease-causing pathogens, treatment, and intervention. Additional research focuses on developing vaccines and better understanding of immune function and biological responses to disease.

Nutrition Physiology

Nutrition is a vast toolkit that can be used to optimize animal growth, development, and well-being. Research in the Nutritional Physiology Group within the Department of Animal science focuses on nutritional strategies that benefit production of a variety of animal species, including beef and dairy cattle, horses, and poultry. Genomics, biochemistry, and molecular biology are integrated with whole animal physiology and on-farm studies to address a range of nutrition research questions using modern, interdisciplinary approaches. Challenges currently addressed by this research group include the following:

  • Optimizing diet to enhance growth and efficiency
  • Enhancing animal health and well-being
  • Integrating grazing management and nutrient supplementation with forage availability and quality
  • Reducing the environmental impacts of animal production systems
  • Elucidating molecular pathways that control cellular growth and development

Reproductive Physiology

Sustainability of farm animal production is directly dependent on animals producing live offspring in an efficient manner. Infertility-reproductive inefficiency carries significant economic consequences to all domestic livestock industries. Therefore, gaining an understanding of factors contributing to infertility is of critical importance to maximize reproductive efficiency of domestic livestock species. Research interests of our group include efforts to improve estrous synchronization and timed insemination outcomes, determine transmission and occurrence of reproductive diseases, unravel some of the mysteries related to fetal-maternal communication, identify the mechanisms of and alleviating environmental and endogenous factors that negatively impact embryonic survival, and  improve methods for in vitro embryo production and animal cloning. Our faculty, staff, graduate, and undergraduate students work together to provide a multifaceted approach to research reproductive problems at the whole animal, cellular, and molecular level.
