Abstract
The metabolizable energy (ME) available for milk production was utilized with less heat loss as shown by open circuit calorimetry, as concentrate replaced alfalfa hay wafers in the rations of 6 mature, lactating, nonpregnant Holstein cows. By using an assumed maintenance requirement of 131 kcal/w7This publication has 15 references indexed in Scilit:
