张家口杂交谷子添加水平对断奶至3月龄獭兔生长性能及皮毛质量的影响

Effects of Zhangjiakou hybrid millets supplemental level on growth performance and fur quality of weaner to 3-month-old growing rex rabbits

试验旨在研究饲粮中添加不同水平张家口杂交谷子对断奶至3月龄兔生长性能、毛皮质量的影响。试验选取80只45 d的獭兔,随机分成4组,每组10个重复,每个重复2只。Ⅰ组为对照组,饲喂基础饲粮;Ⅱ、Ⅲ、Ⅳ组为试验组,分别饲喂以15%、20%、25%张家口杂交谷子替代部分玉米和麸皮(换算比例为1谷子=0.55玉米+0.45麸皮)配制的试验日粮。预试期5 d,正试期40 d。结果表明:1在初始体重无显著差异(P>0.05)的情况下,饲粮中添加张家口杂交谷子可明显提高试兔的日增重,降低料重比;其中Ⅳ组日增重(添加量25%)显著高于对照组(P<0.05),同时Ⅳ组料重比显著低于对照组(P<0.05);2饲粮中添加张家口杂交谷子对生长獭兔被毛密度、被毛长度均没有显著影响(P>0.05)。综合以上测定指标,张家口杂交谷子可以作为家兔的能量饲料,在生长獭兔饲粮中添加水平25%为最佳。

This experiment was conducted to study the effects of Zhangjiakou hybrid millets supplemen- tal level on growth performance and fur quality of weaner to 3-month-old growing Rex rabbits. A total of 80 45-day-old healthy rex rabbits with similar body weight were randomly divided into 4 groups with 10 replicates per group and 2 rabbit per replicate. Group I was the control group, fed the basal diet;Ⅱ、Ⅲ、 and Ⅳ as the experimental group were fed with 15%, 20%, 25% of Zhangjiakou hybrid millet alternative part of corn and wheat bran （conversion ratio was 1 millet = 0.55 corn ＋ 0.45 bran） is formulated experimental diets..The experiment was lasted for 45 days. The results showed as follows： ① in the initial weight no significant difference （P〉0.05）, the diets added Zhangjiakou hybrid millet can significantly improve rabbit daily weight gain, lower feed heavy ratio; the group IV gain weight （add 25%） was significantly higher than that of the control group （P〈0.05）, also in group IV materials heavy ratio was significantly lower than that of the control group （P〈0.05）; ② diet add Zhangjiakou hy- brid millet on growing rex rabbits was hair density, hair length had no significant effect （P〉0.05）. Based on the above indexes, Zhangjiakou hybrid millet can be as energy feed for rabbits in growth of Rex Rabbit diet and add 25% level for the best.
