Strategic Approaches To Develop Optimal Feeding Program Of Brown Midrib Corn Silage To Lactating Dairy Cows In The Intermountain West, Michael Shane Holt

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In two lactation studies reported in this dissertation, it was hypothesized that feeding 35% brown midrib corn silage (BMRCS) and 25% alfalfa hay (dry matter basis) would result in increased dry matter intake (DMI) around peak lactation compared with feeding conventional corn silage (CCS), causing longer peak milk production, and that feeding dairy cows in early lactation a 16% crude protein diet with fair quality alfalfa hay (FAH) in BMR-based diets would maintain milk production, reduce urinary N excretion, and improve N efficiency compared to those fed high quality alfalfa hay ( …
