摘　　要：为了比较用NRC(1998)生长模型的胴体分离法和全胴体法预测长白×荣昌(简称长×荣)杂交仔猪赖氨酸需要量的差异,我们开展了本试验。结果表明:用NRC(1998)生长模型胴体分离法估测的10～20kg长×荣杂交仔猪的赖氨酸需要量与全胴体法预测的值无明显差异,证明NRC(1998)生长模型的胴体分离法对我国的长×荣杂交仔猪同样适用。Abstract： This study was conducted to compare the NRC （1998） growth model with the method of whole carcass in forecasting lysine requirement of Landrace×Rongchang crossbred piglets. The results suggested that the difference of the lysine requirement of Landrace×Rongchang crossbred piglets at the stage of 10×20 kg was insignificant between the NRC （1998） growth model and the method of whole carcass. Therefore the parameters in the growth model of NRC （1998） was applicable to Landrace× Rongchang crossbred piglets in ChinaJ
