摘要：
[Objective]The paper was to investigate the effects of crude protein level of concentrate supplement on production performance and serum biochemical parameters of post-fattening Hainan Yellow Cattle.[Method]Twelve Hainan Yellow Cattles with the same genetic backgrounds and similar initial weight of(168.13±0.55)kg were randomly divided into three treatments.Cattle were fed with concentrate supplement containing different levels of crude protein.The trial lasted 60 d.[Result]The daily gain of 17.56%crude protein group was significantly higher than those of 15.55%and 13.56%crude protein groups(P<0.05),and the gross profit of 17.56%crude protein group was markedly higher than that of 13.56%crude protein group(P<0.05),but the feed gain ratio of 17.56%crude protein group was significantly lower than that of 13.56%crude protein group(P<0.05).Compared with 15.55%and 13.56%crude protein groups,the serum total protein content markedly increased(P<0.05),but the urea nitrogen level significantly decreased(P<0.05).[Conclusion]When crude protein level of concentrate supplement was 17.56%,post-fattening Hainan Yellow Cattle could obtain better production performance.
