- Abstract
[Objective] This paper was to study effects of pelleted total mixed ration with different concenlrate-roughage ratios on production performance and serum biochemical parameters of fattening Hainan black goats. [Method] Thirty-six fattening Hainan black goats with the same genetic background and similar initial weight of (14.08+0.13) kg were randomly assigned into three treatments. Goats were fed with Juncao + concentrate (control group), pelleted total mixed ration I (concentrate: roughage 50;50, group I) and II (concentrate: roughage 45;55, group II), respectively. The test lasted 45 d. [Result] The final weight, daily gain and feed intake of rams in experimental group 1 were significantly higher than those of control group and experimental group II (P<0.05); the final weight and daily gain of rains in experimental group I were also markedly higher than those of experimental group II (P<0.05); the feed/gain of rams in experimental group I was significantly lower than those in control group and experimental group If (P<0.05). The feed gain cost of rams in experimental group T was markedly lower than that in experimental group TT (P<0.05), but was significantly higher than that in experimental group 1 (P<0.05); the gross profit of rams in experimental group 1 wras significantly higher than those in control group and experimental group 11 (P<0.05). Compared with control group and experimental group 11, the serum total protein and glucose levels in experimental group 11 increased significantly (P<0.05), but the urea nitrogen content reduced (P>0.05). [Conclusion] When the concentrate-roughage ratio ol pelleted total mixed ration was 50:50, the fattening effect of Hainan black goal was better, and the serum total protein and glucose levels were evidently improved.
