Effects Of Feeding High-Moisture Corn Grain With Slow-Release Urea In Dairy Diets On Lactational Performance, Energy And Nitrogen Utilization, And Ruminal Fermentation Profiles By Lactating Cows, Braden M. Tye
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The objective of this experiment was to determine if nutrient utilization and energy partitioning by lactating dairy cows would differ in response to dietary corn grain (CG) types [steam-flaked corn (SFC) vs. high-moisture corn (HMC)] and to test if the types of CG would interact with slow-release urea (SRU) on lactational performance and energy utilization. Eight multiparous Holstein cows (32 ± 8.2 days-in-milk) were used in a duplicated 4 × 4 Latin square with one square consisting of ruminally cannulated cows. A 2 × 2 factorial arrangement was used to test 4 dietary treatments: SFC without SRU, SFC with SRU, …
