摘要
本试验旨在研究辽宁绒山羊空怀期母羊的能量需要量。选用体况良好、体重接近的24只辽宁绒山羊经产空怀母羊,随机分为3组,每组8个重复,每个重复1只。采用饲养试验、消化代谢试验和气体代谢试验研究绒山羊空怀母羊的代谢能(ME)和净能(NE)的需要量。结果表明:辽宁绒山羊空怀期母羊的维持需要代谢能和净能分别为0.480和0.336 MJ/kg W0.75。
This research was conducted to study the energy requirements for barren ewes of Liaoning cashmere goats.Twenty-four Liaoning cashmere barren ewes were divided randomly into 3 groups with 8 replicates in each group and 1 goat per replicate.Requirements of metabolizable energy and net energy were determined using feeding experiment,digestion and metabolism experiment and gas metabolism experiment.The results show that metabolizable energy and net energy for maintenance of barren ewes of Liaoning cashmere goats are 0.480 and 0.336 MJ/kg W0.75,respectively.
