【摘要】 本试验旨在研究基础日粮中添加复方中草药对围产后期奶牛产奶量及乳成分的影响,为更好地发挥奶牛生产性能提供理论依据。选用围产期荷斯坦牛32头,按照年龄、胎次、预产期相近的原则,随机分成四组,对照组饲喂常规基础日粮,处理A组、处理B组、处理C组添加由黄芪、党参、香附、白术、当归、川穹、白芍、熟地等组成的复方中草药,产前21d至产后21d连续饲喂42d,添加量分别为50g/d、100g/d、150g/d。试验结果表明,处理A组、处理B组、处理C组与对照组相比,产奶量分别提高了2.74kg、4.87kg、4.73kg,差异显著(P<0.05),表明复方中草药能显著提高奶牛产奶量。基础日粮中添加复方中草药对乳成分的影响无明显变化规律,处理A组、处理B组、处理C组的干物质含量、乳脂率、乳蛋白率、乳糖率与对照组相比差异不显著(P﹥0.05)。更多还原

【Abstract】 The objective of study was to investigate the effects of Chinese herbal medicine additive on milk yield and milk composition of peripartum dairy cows, and provide theoretical basis and methods to exert the production performance of dairy cows. A total of 32 Chinese Holstein cows with similar calving date, parity and milk production were randomly divided into 4 groups: control group, group A, group B and group C. The control group cows were fed basal diet, the experimental groups were fed diet added prescription Chinese herbal medicine from prenatal 21 days to postpartum 21days(total 42 days).The amount of Chinese herbal medicine added per cow in group A, B, and C was respectively 50 g/ d,100g/d and 150g/d. The results showed that milk yield were significantly improved by adding Chinese herbal medicine additive in diets of cows in peripartum(P<0.05). Per cow milk yield of group A, B, C were improved 2.74 kg/d, 4.87 kg/d and 4.87 kg/d respectively. Differences of milk compositions were of no significance(P>0.05).The differences on content of milk dry matter, milk fat, milk protein, milk lactose were of no significance among control group, group A, group B and group C.更多还原
