In order to investigate the feeding standardization of protein,by means of one-factor experiment,15 healthy 2-year-old female Liaoning cashmere goats were randomly divided into 3 groups,5 in every group,to study the effects of different protein levels(9.26%,10.06%,11.02%) on production of cashmere and digestion and metabolism.The results showed that dietary protein levels had no significant effect on performance of cashmere(P0.05);retained N was 4.94 g/d respectively in group Ⅲ,significantly higher than that of the other two groups(P0.05).There was no significant difference(P0.05) of CF digestibility and GE metabolism among the three tested groups.It was suggested that the dietary protein level was 11.02% for feed-lot Liaoning cashmere goat.
