|
| Abstract: |
| The chemical composition and amino acid component of ten Chinese feedstuffs were measured and compared with one another.The protein quality:True Digestibility(TD),Biological Value(BV),and Net Pr- otein Utilization(NPU)were determined in N-balance experiments wi- th growth rats. The Biological Value of feedstuffs were(%):Barley 71.5,Maize 65.7,Sorghum 85.9,Wheat Bran 80.9,Soybean meal 74.9,Black Soy- bean meal 74.5,Sunflower meal 71.5,Sesame meal 73.9,Leaves of Lo- cust 97.1 and Common comfeay 51.8.
