This trial was conducted to evaluate the effects of replacing corn silage with sugarcane on intake, apparent digestibility of nutrients, ruminal pH and ammonia nitrogen, and ruminal passage rate of digesta in lactating dairy cows. Proportion sugarcane increased as follows: 0, 33.3, 66.6 and 100% of the forage portion of the diet. Twelve Holstein and crossbred Holstein/Zebu cows with potential yield varying from 5,000 to 7,000 kg of milk per lactation were randomly assigned to three 4×4 Latin squares. Cows […]
