Rabbits in experimental groups Ⅰ,Ⅱ,Ⅲ and Ⅳ were fed with different quantita-tive complete formula feed and unlimited fresh grass of C. gyroides, and those in group Ⅴ(control group) were fed with complete formula feed. The indicators such as feed intake and growth performance were measured after 60 d. The results showed that the gaining effects of meat rabbits in ex-perimental groups Ⅳ and Ⅲ were most obvious, and the daily gain reached(25.75 ±3.00) and(24.50±1.95) g, 20.72% and 14.86% higher than those in control group, respectively. The conversion efficiency of dry matter in experimental group Ⅲ was the highest, and only 2.99 g of C. gyroides and compound feed dry matter was consumed for the growth of 1 g of rabbit meat, receiving significant economic benefit.展开更多
