Effect of supplementation of concentrates differed rumen degradable protein content on milk production, nitrogen and energy balances in lactating dairy cows offered high-corn silage diets



Effect of supplementation of concentrates differed rumen degradable protein content on milk production, nitrogen and energy balances in lactating dairy cows offered high-corn silage diets



Memoirs of the Graduate School of Agriculture, Hokkaido University 24(3/4): 381-388



A study was conducted to determine the effect of rumen degradable protein (RDP) on mil production, and nitrogen and energy balance in lactating dairy cows. The cows were fed maize silage (MS) containing high nonfibrous carbohydrate (NFC), hay and concentrates with different RDP values: high RDP (soyabean meal) and low RDP (maize gluten meal). Dry matter intake, and milk yield and composition did not differ in the 2 RDP treatment groups.
