Abstract
   Corn silage is feedstuff produced by the fermentation of whole part or some part of corn plants. Corn silage had a high energy and low protein that commonly used as supplemental energy for lactating dairy cows. High carbohydrate complex like cellulose in corn silage is a good source for microbial rumen to increase volatile fatty acid (VFA) production and thus improved milk production. Aim of this study was to determine effect of complete feed based on silage of corn biomass to improve milk production and quality of dairy cows. In total of 16 dairy cows in the second parity with average body weight 567 kg were used in this experiment. Completely randomize design was used in this study with 4 treatment (R1: 60% corn biomass silage (CBS) + 40% concentrate (Con); R2: 60% CBS + 10% forage (FOR) + 30% Con; R3: 60% CBS + 20% FOR + 20% Con; R4: 60% CBS + 30% grass + 10% Con) were replicated four times. Different combination of between CBS, forage and concentrate did not effect on milk quality and milk production both of real or 4% FCM. However, it can improve milk qualities such as solid non-fat, fat, and protein percentages by 8%, 4% and 2.8%, respectively. It also can maintain of 10 – 12 kg/cow/day milk production and 11.63 – 12.75 kg/cow/day of FCM. Similar results in all treatment indicated that the complete feed in four treatments have a same nutrient qualities. In conclusion, feeding dairy cows with complete feed based on corn biomass silage can maintain milk production and improve milk qualities.
