This experiment was conducted to determine the effect of protein level on performance and serum biochemical indicators in dairy goat. 45 healthy dairy goats in lactation with same weight, milk yield, parous (2~3 times) were used by single-factor randomized design and equally divided into 3 groups and 15 goats per group. Dietary protein level was 10%, 12.5% and 15% respectively. It was 10 days in advance to do the preparation of experiments, followed by the period of time in true experiments with 35 days. Results: The higher dietary protein levels can increase milk production significantly (P<0.05); the milk protein yield in group received 12.5% dietary protein level was nearly-identical to group with 15% P>0.05), the group of 12.5% have the highest milk contents, The goat albumin, urea nitrogen content in group with 12.5% and 15% dietary protein level were significantly hig..
