摘要
选取80只成龄乌苏里母貉,随机分成试验、对照各1组,试验组饲喂添加剂,进行对比饲养实验。结果表明:该添加剂可以有效地提高母貉的繁殖性能,使其配种时间及产仔相对集中且时间较为合理;改善母貉营养水平,促进发情和排卵,明显降低空怀率,试验组比对照组空怀率低13.89%;平均产仔数和产仔成活数差异均不显著(P>0.05)。
80 adult female raccoon dogs(Nyctereutes Ussurienusis Matschie) were selected, and divided into two groups at random.One for experimental group,the anather for control.The experimental raccoon dogs were fed with the additives and compared with the other group. The results showed that the additives could improve the progenitive performance of female raccoon dogs,which made the mating and parturition time of the raccoons relatively centralized, and improve the nutritive level of female raccoon dogs.and debased significantly the precentage of no gravidity (experimental one is 11.11%;and 25% for control,no gravidity ratio lower 13.89% for the experimental one than that of the control.The number of kits and the surviving number were not significant (P>0.05).
