Assessments Of An Exogenous Proteolytic Enzyme In Beef Steer Diets To Improve Growth Performance And Ruminal Fermentation, Juan Manuel Vera
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
A series of experiments were conducted to investigate the effects of adding an exogenous proteolytic enzyme (EPE) on growth performance and ruminal fermentation characteristics of beef steers fed growing and finishing diets containing 30% dried distillers grains with solubles (DDGS).
In the first experiment, 48 beef steers were divided into two treatments: DDGS diets with and without EPE. Dry matter intake (DMI) was increased (P = 0.02) by the addition of EPE, but neutral detergent fiber (NDF) digestibility was decreased on the growing phase. For the finishing phase, average daily gain ( …
