邛崃波尔山羊饲养水平的评价

在邛崃波尔山羊场选择波尔山羊成年健康母羊(怀孕前期)30只,种公羊(非配种期)5只,称体重。通过预试期14d,测定6d平均采食量,计算其摄入的营养成分含量,并与美国NRC肉用山羊饲养标准比较,进行饲养水平评价。结果表明,与饲养标准比较,波尔山羊母羊和种公羊日粮消化能分别高7.44MJ和3.28MJ、可消化粗蛋白分别高67.04g和42.42g,钙母羊高1.79g、公羊低1.38g,磷母羊高1.71g、公羊低0.09g,钠母羊和公羊分别低7.22g和8.06g。结合羊只的体况,综合评定该场波尔山羊饲养水平基本合理,但尚需提高母羊、公羊钠的供给量和公羊钙、磷的供给量。

The Evaluation of the Feeding Level of Boer Goat in Qionglai Feed

Thirty abult and healthy does(protestation)and five seminal bucks (non-hybridization)were selected and weighed.Through a14day experimental,their average amount of food intake and how many nutritional elements they were measured and then compared with the feeding standard of American NRC goats breed for slaughter to evaluate each feeding level.The results showed that the digestion of does and bucks of Boer Goat were respectively7.44MJ and3.28MJ higher than that of American NRC goats breed for slaughter.The calcium of the does was is1.79g higher,but bucks were1.38g lower.The sodium of the does and buck was respectively7.22g and8.06g lower than that of American NRC goats breed for slaughter.According to the heath of the Boer Goat,it was basically reasonable to assess synthetically the feeding level in the farm but there is still a need to improve the supply of sodium for does and bucks and the calcium and phosphorous for bucks.
