Nutrient Utilization, Lactational Performance, And Profitability Of Dairy Cows By Feeding Protein Supplements In High-Forage Lactation Diets, Kathryn Neal
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Due to the increasing cost of soybean meal and concerns of excess N being excreted into the environment, new protein supplements have been developed. Two products that have shown potential in increasing N utilization efficiency are slow release urea (SRU; Optigen) and ruminal escape protein derived from yeast (YMP; DEMP). The objective of this study was to assess the effects of feeding these 2 supplements in high-forage [(54% of total dietary dry matter (DM)] dairy diets on nutrient utilization, feed efficiency, lactational performance of dairy cows, and their impacts on income-over feed costs. Twelve …
