摘要
以生长獭兔为对象,研究了日粮中添加不同浓度的“健兔散”对增重、屠宰性能、肉品品质和毛皮品质的影响。结果表明:每千克日粮添加10g、20g、30g的“健兔散”,试验兔平均日增重分别比对照组提高15.47%(P<0.05)、25.88%(P<0.01)、24.12%(P<0.01)。料重比分别比对照组降低了13.41%、22.03%和20.15%。20g、30g添加组均可显著提高日粮粗蛋白质消化率(P<0.05)。20g添加组可极显著提高日粮粗脂肪的消化率(P<0.01),30g添加组可显著提高粗脂肪的消化率(P<0.05)。不同添加量对獭兔屠宰性能、肌肉品质、毛皮品质均无显著影响,其中熟肉率、皮张面积、被毛密度有增加趋势,但各组间差异不显著(P>0.05)。
The Rex rabbit was used to study the effect of “Jian Tu San”additive at three levels(10g/kg, 20g/kg, 30g/kg) on feed upon the weight-gain, meat quality and the fur quality.The results show that the rate of weight-gain of three test groups was 15.47%(P<0.05),25.88%(P<0.01) and 24.12%(P<0.01) higher respectively than that of the control group.The conversion index of the groups was 13.41%, 22.03%and 20.15%lower respectively than that of the control group. The group 3, 4 presented a remarkably higher coarse protein digestion rate. The test group 3 has a very remarkably higher fat digestion rate(P<0.01). The test group 4 only has a remarkably higher fat digestion rate (P<0.05).Variable quantities of the additive have no remarkable effect upon dressing percent, them eat quality and fur quality. Though the meat ripening rate, leather area, hair densityhave a trend of increasing respectively, the difference was not remarkable (P>0.05). Inconclusion, the results of the present work shows that the inclusion of “Jian Tu San”additive could improve the performance (digestibility and growth) of Rex growing rabbits without any effect on meat and fur quality.
