摘      要：正The study was to provide the Chinese Feedbank with intestinal digestibility（Idg）of crude protein（CP）and AA for feedstuffs commonly used in *** various AA of feedstuffs weren’t synchronously digested,while a larger variation was found in the same AA between *** CP Idg estimated by mobile nylon bag technique in soyabean meal,cottonseed meal,peanut cake meal,rapeseed meal,rice bran,maize germ meal,wheat bran and lucerne hay were 0.964,0.813, 0.950,0.826,0.586,0.793,0.679 and 0.400,*** has a strong correlation with the value obtained by three-step in vitro procedure.
