Scientist in the Nutrition and Environmental Management Research Unit conduct studies to determine the role of maternal nutrition during pregnancy on growth and fertility of their progeny.
The Nutrition and Environmental Management Research Unit identifies nutritional, physiological, and environmental mechanisms responsible for differences in efficiency of nutrient utilization by feedlot cattle. Additionally, we develop nutrient management strategies to improve feed utilization and minimize potential impacts of beef cattle production on the environment.
Swine nutrition research in the Nutrition and Environmental Management Research Unit is focused on improving feeding efficiency in growing swine. Basic research is conducted in this area to identify the molecular differences in animals at are efficient in converting nutrients to lean growth, compared to inefficient animals. Additionally, applied research is conducted to identify strategies, such as feed additives and management strategies, to improve feed efficiency.
Nutrition and Environmental Management Research Unit scientist conduct research to determine the impact of heifer development strategies on subsequent cow performance.
The Nutrition and Environmental Management Research Unit is developing precision livestock farming techniques such as imaging to develop a data stream on individual animals that can be used to inform producers to help make management decisions. Research in this area provides a basis for individual animal care in commercial facilities, provides a better understanding of the animal interactions to improve pen design, and to quantify genetic variation.
Researchers in the Nutrition and Environmental Management Unit collect gas samples to measure ammonia and greenhouse gas emissions from corn fields receiving beef feedlot manure and commercial fertilizer. Nutrient partitioning to plants, air emission, and leaching are also measured.
The mission of the Nutrition and Environmental Management Research Unit is to develop knowledge and technology to improve the efficiency of livestock production, and minimize the environmental impact of beef cattle, sheep, and swine. Research emphases include 1) Improving the efficiency of utilization of feed resources for the production of edible products, 2) Minimizing the environmental impact of livestock waste, and 3) Increasing the competency of beef cattle reproduction.
