日粮中添加不同比例竹枝粉对肉兔生长性能和屠宰性能的影响

Effect of Different Proportions of Bamboo Powder in the Basic Diet on Rabbit Growth and Slaughter Performance

选取176只30日龄体重相近的加利福尼亚断奶肉兔,随机分成4组,Ⅰ、Ⅱ、Ⅲ组为试验组,分别在基础日粮中添加10%竹枝粉+17%苜蓿草粉、15%竹枝粉+12%苜蓿草粉、18%竹枝粉+9%苜蓿草粉;Ⅳ组为对照组,在基础日粮中添加27%苜蓿草粉,研究在日粮中添加不同比例竹枝粉替代苜蓿草粉对肉兔生长和屠宰性能的影响。结果表明,试验各组料重比均极显著低于对照组(P<0.01),分别比对照组降低了16.27%、10.62%和3.47%;试验各组日增重极显著高于对照组(P<0.01),分别比对照组提高了19.29%、9.19%和3.67%;试验各组半净膛屠宰率极显著高于对照组(P<0.01),分别比对照组提高了2.61%、1.35%和0.26%;试验各组全净膛屠宰率极显著高于对照组(P<0.01),分别比对照组提高了2.98%、2.55%和0.80%。提示,添加10%竹枝粉+17%苜蓿草粉效果最明显。

176 thirty-day-old California weaned meat rabbits with consistent weight were randomly divided into four groups,Ⅰ, Ⅱ, Ⅲ groups were the test groups, adding 10% bamboo powder and 17% alfalfa meal, 15% bamboo powder and 12% alfalfa meal, 18% bamboo powder and 9% alfalfa meal in the basic diet, respectively. Ⅳ group was control group, adding 27% alfalfa meal in the basic diet.The aim was to study the different proportions of bamboo powder instead of alfalfa meal on growth performance and slaughter performance in meat rabbit. The results showed that feed to gain ratio of each test group was extremly significantly lower than control group （P〈0.01）, reduced by 16.27%, 10.62%, 3.47%, respectively. Daily gain of each test group was extremly significantly higher than the control group （P〈0.01）, increased by 19.29%,9.19%,3.67%, respectively. Half net slaughter rate of each test group was extremly significantly higher than control group （P〈0.01）, increased by 2.61%, 1.35%, 0.26%, respectively. Net whole slaughter rate of each test group was extremly significantly higher than control group （P〈0.01）, increased by 2.98%, 2.55%, 0.80%, respectively.The results revealed that adding 10% bamboo powder and 17% alfalfa meal had the best effect.
