Stage of lactation and corresponding diets affect in situ protein degradation by dairy cows
Our objectives were (1) to measure and compare in situ ruminal CP degradation parameters and RUP of selected protein sources and TMR samples in dairy cows fed diets for 3 stages of lactation, and (2) to determine the hydrolysis time needed for an in vitro Streptomyces griseus procedure that would generate extent of undegraded CP corresponding to in situ RUP
measurements.
