Milk Yield and Nutrient Adequacy of Lactating Dairy Cow Fed Based on Tofu Waste, Soybean Hulls and Straw

This study was done to assess the adequacy of nutrient intake and feed efficiency in dairy cows using agricultural byproducts as feedstuff. Treatments of feed in this study refered to the pattern of feed given by farmers with different feed ingredients formula i. e (T1, 21.42 % tofu waste, T2, 19.00 % tofu waste, T3, 38.18 % tofu waste + 16.50 % soybean hulls + 8.86 % straw, T4, 32.71 % tofu waste + 23.10 % straw, T5, 25.20 % tofu waste +5.96 % soybean hulls, T6, 9.13 % tofu waste + 32.80 % straw, T7, 21.99 % tofu waste + 28.58 % straw, and T8, 30.52 soybean hulls). The variables measured were dry matter intake (DMI), crude protein intake (CPI), total digestible nutrients (TDN), milk production, milk composition and feed efficiency. Data were analyzed using t-test as independent samples. DMI did not met the requirement of dairy cows except for cows received T4 and T3, while the protein requirements of cows met except for cows received T7 while TDN requirement only met for cows received T3, T5 and T6. The highest milk yield was for cows received T8. It can be concluded that the pattern of feeding in Cibungbulang smallholder dairy farm varied so the milk yield also varies and T3 showed the best feed formula.
