| 摘 要： | 旨在评价酵母培养物(YC)对公猪生产性能的影响。将90头体重约为80kg的公猪随机分为3组,即对照组、试验Ⅰ组和试验Ⅱ组;对照组饲喂基础日粮,试验Ⅰ组和试验Ⅱ组基础日粮中分别添加5kg/t和7kg/t的酵母培养物,预试期5d,正试期45d,试验期间,3组饲养管理条件一致;试验结束时,评定各组公猪精液的颜色、气味,测定并比较各组公猪的精液量、精液pH值、精子活力、精子密度、精子畸形率、抗力指数。结果表明,试验Ⅰ组和试验Ⅱ组公猪的精液颜色和精液气味与对照组相比没有明显差异;3组公猪的精子抗力指数一致;试验Ⅰ组和试验Ⅱ组的精液量、精子活力、精子密度均显著大于对照组(P<0.05),精子畸形率均显著小于对照组(P<0.05),但这4项指标在2个试验组之间差异均不显著(P>0.05);3组公猪的精液pH值差异均不显著(P>0.05)。综上提示,基础日粮中添加一定量的酵母培养物能够提高公猪部分生产性能指标。

Effect of Dietary Supplementation of Yeast Culture on Productive Performance of Boar |
| |
| Abstract: | This study was designed to assess the effect of yeast culture(YC)on productive performance of boar.A total of 90 boars weighing approximately 80 kg were randomly assigned to one of three groups(n=30)such that control group was fed with the basal diet,experimentalⅠgroup(n=30)and experimentalⅡgroup(n=30)were fed with the basal diet supplemented with 5 kg/t and 7 kg/t of yeast culture,respectively.The period of the pre-experiment and formal-experiment lasted for 5 d and 45 d,respectively.During the whole experiment process,the boars of the three groups were reared under the same feeding and management condition.At the end of the experiment,the semen color and flavor of the boars from different groups were evaluated;the semen volume and pH value as well as the sperm motility,density,abnormal rate and resistance index of the boars from different groups were also determined and statistically compared.The results showed that no obvious differences in semen color and flavor between the boars from experimentalⅠgroup and experimentalⅡgroup were observed;the three groups had the same sperm resistance index;the experimentalⅠgroup and experimentalⅡgroup had significantly higher semen volume,sperm motility and sperm density as well as significantly lower sperm abnormal rate compared to the control group(P<0.05),but no significant differences in the above four indexes between experimentalⅠgroup and experimentalⅡgroup were found(P>0.05);there was no statistical difference in semen pH value between the three groups(P>0.05).These results indicate that dietary supplementation of yeast culture can improve the productive performance of boar. |
