摘要
为修订我国猪饲养标准,选用华南地区杜大长生长肥育猪,测定了其在20～100kg阶段的胴体指标,用无脂瘦肉生长速度预测了赖氨酸需要参数.结果表明应用实测的无脂瘦肉生长速度预测的赖氨酸需要参数与生产实际接近.用实测的无脂瘦肉生长速度建立了赖氨酸需要量的数学模型:真可消化赖氨酸需要量(mg/d)=7652 7059+115 3600m+1 1718m2-0 0188m3+36 0000m0 75(m为体质量).
In order to promote the application of NRC(1998) nutrient requirement model in China and revise feeding standards for Chinese pigs, carcass fatfree lean growth rate of Duroc×Large White×Landrace growingfinishing pigs was measured by dissecting carcass or predicted by carcass parameters. The following mathematical model of lysine requirement was established: The true digestible lysine requirement (mg/d)=7 652705 9+115360 0 m+1171 8 m2-0018 8 m3+36000 0 m075 (m is the body mass). The nutrient requirements were predicted on the basis of this model. The values of major nutrient requirements predicted by carcass fatfree lean growth rate measured by carcasses dissected were meaningful.
