微生物发酵饲料对泌乳奶牛生产性能和饲粮养分表观消化率的影响
Microbiology Fermented Feed:Effects on Performance and Hutrient Apparent Digestibility of Lactating Dairy Cows
摘要
Abstract
The objective of this paper was to investigate the effects of microbiology fermented feed on milk yield,milk quality and nutrient apparent digestibility of Holstein Friesian dairy cows. Two hundred and ten lac-tating dairy cows with similar milk yield and body condition were randomly divided into control group,groupⅠ and group Ⅱ,and seventy cows were in each group. Control group was fed with total mixed ration of the farm( basal diet),groupⅠand groupⅡwere fed with diets replaced 1 and 2 kg the concentrate in basal diet with equal quality of microbiology fermented feed,respectively. The feeding trial lasted for 10 pre-feeding days and 24 trial days. Milk yield,milk composition and apparent digestibility of nutrients were determined. The re-sults showed as follows:1)during of this trial,the milk yield in whole period of group Ⅰ( replaced 1 kg) and group Ⅱ( replaced 2 kg)were increased by 3.42%( P<0.05)and 4.40%( P<0.05)than that of control group,respectively. 2)Group Ⅱ had better milk composition and density than control group( P<0.05). Milk protein,milk fat and lactose contents of group Ⅱ were increased by 3.11%( P<0.05),6.71%( P<0.05)and 2.92%(P<0.05)compared with groupⅠ. 3)The nutrient apparent digestibility of groupⅡwas significantly higher than that of control group( P<0.05),and the apparent digestibility of dry matter,( crude protein and acid detergent fiber of group Ⅰ was higher than that of control group( P<0.05). In conclusion,the appropri-ate microbiology fermented feed level can enhance milk yield and nutrient apparent digestibility and improve milk quality. Replacing concentrate with 2 kg microbiology fermented feed in dairy cows is better than that with 1kg.关键词
