舍饲条件下不同日粮饲喂中卫山羊后备母羊试验

Experiment of feeding Zhongwei goat with different diets under the condition of raising in shed

探讨了中卫山羊后备母羊适宜的营养水平和饲料配比,以便为养羊生产提供科学依据.采用两种配合日粮对中卫山羊后备母羊进行了饲喂试验,并以生产中采用的日粮作对照,结果表明:饲喂试验日粮的试验I组、Ⅱ组,试验期内总增体质量和平均日增体质量均极显著地高于对照组(P<0.01),而料质量比和单位增体质量所需的饲料成本则明显地低于对照组.试验Ⅰ组的平均日增体质量、饲料转化率以及采食量略高于试验Ⅱ组,试验Ⅱ组则以饲料单价和单位增体质量所需的饲料成本低而见长.

Suitable nutrition level and diets for the reserve she-goats of Zhongwei Goat were found out to provide scientific basis for feeding goats. The feeding experiment was carried out by comparing with the diets in production. The results showed that the total weight gain and average daily gain of the tested Group I and group Ⅱ were extremely significantly higher than those of the control group （P〈 0. 01） and the ratio between feed consumption and weight gain and the feed cost for weight gain in the tested groups were significantly lower than those in the controled group. Group I was a little better than group Ⅱ in average daily gain, efficiency of feed utilization and feed intake. Group Ⅱ was better in the low feed price and cost for weight gain.
