Intestinal digestibility of protein and amino acid of ruminant feeds with the mobile nylon bag and in vitro digestion technique

摘要：

The study was to provide the Chinese Feedbank with intestinal digestibility (Idg) of crude protein (CP) and AA for feedstuffs commonly used in China. The various AA of feedstuffs werent synchronously digested, while a larger variation was found in the same AA between feedstuffs. The 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, respectively. It has a strong correlation with the value obtained by three-step in vitro procedure.
