| 摘 要： | 选择75只12月龄努比亚羊集中配种,配种后将母羊随机分为3组,分别补饲复合预混料+尿素、浓缩料和精料补充料,在配种(0 d)、妊娠100 d、妊娠150 d进行体重、体尺测耸和体况指数计算.研究结果表明:补饲精料补充料的母羊体重和体尺均大于补饲浓缩料组和补饲尿素组,3组之间存在明显差异.母羊体况指数(BCI)随妊娠期而上升,3组间存在显著差异.以体重(y)、胸围(x1)和体高(x2)建立的最优回归方程为:y=-38.330+0.63x1+0.38x2,R2=0.7547.

| Abstract: | 75 Nubian ewes were selected and divided into 3 groups randomly.Besides basic grazing,three groups of goats were treated 2% premix and urea 10 g/d(the added urea group),concentration 100 g/d(the added concentration group) and concentration supplementation 250 g/d(the added concentration supplementation) respectively.Body weight,body conditions and body size were measured at the breeding day,100-day of pregnancy and 150-day of pregnancy.The results showed as follows:The added concentration supplementation gr... |
