摘要 为了验证NRC(1998)生长模型对我国长×荣二元杂交仔猪的适用性并确定其氨基酸需要量,试验选用体重约10kg的长×荣公猪和母猪各15头,通过饲养试验和屠宰试验测定其生产性能、胴体无脂瘦肉生长指数及胴体成分,结合杨飞云等(2002)20~100kg长×荣生长肥育猪的试验结果,建立日增重与体重、胴体无脂瘦肉生长指数与体重、体蛋白沉积速度与体重之间的回归方程。根据胴体无脂瘦肉生长指数与体重的回归方程以及无脂瘦肉的蛋白质沉积系数和蛋白质沉积的赖氨酸需要系数,建立长×荣杂交猪赖氨酸需要量的数学模型,利用此数学模型预测10~20kg长×荣杂交猪的氨基酸需要量,并用全胴体法进行验证。试验结果显示:①根据NRC(1998)生长模型,用胴体分离法建立10~100kg长×荣杂交猪赖氨酸需要量的数学模型为:真可消化赖氨酸需要量(mg/d)=-0.0515BW3+5.5412BW2-16.904BW+5189.6+36BW0.75,据此模型计算10~20kg长×荣杂交猪的真可消化赖氨酸需要量为6.28g/d,总赖氨酸需要量为7.26g/d;按占风干日粮百分比表示的真可消化赖氨酸需要量为0.69%,总赖氨酸需要量为0.80%。其它必需氨基酸的需要量按NRC(1998)推荐的理想蛋白氨基酸模式中各种氨基酸与赖氨酸的比例计算;②用全胴体法测得10~20kg长×荣杂交猪的赖氨酸沉积速度为5.32g/d,?
