متن کاملFat-Feeding Practices for Lactating Dairy Cows
Supplementing cows with fat can have several beneficial effects. It usually increases the energy density of the diet as starch or fiber is replaced with fatty acids. If milk production is increased, then feed efficiency may be improved. Less heat may be produced in the rumen during digestion of fat-supplemented diets as fatty acids are not digested in the rumen. Less heat produced during digest...
