为分析和探讨不同的环境温度和湿度对兔子产仔性能的影响,选择湖北省恩施州咸丰县某养兔基地的60只雌性中国家兔作为研究对象,监测和比较不同环境温湿度对受孕率、每窝产仔数、初生窝仔存活率、初生仔兔体重、30日龄断奶兔体重等指标.结果常温组的受孕率、每窝产仔数、初生窝仔存活率、断奶兔体重均显著大于高温组和低温组,差异具有统计学意义(P<0.05);常湿组的受孕率、每窝产仔数、初生窝仔存活率、断奶兔体重均显著大于高湿组和低湿组,差异具有统计学意义(P<0.05).表明当外界环境温湿度发生改变时,可对兔子的产仔性能造成较大影响,其中常温、常湿环境条件下可显著促进本地区兔子的产仔性能,这为本地区兔养殖寻找合适的最佳环境温湿度,提高和推广兔养殖效益提供科学的参考依据.
The Effect of Changes in Environmental Temperature and Humidity on the Perfor-mance of Rabbit Littering
To analyze and explore the effects of different environmental temperatures and humidity on rabbit litter performance.Sixty female Chinese rabbits from a rabbit breeding base in Xianfeng County,Enshi Prefecture,Hu-bei Province were selected as the research subjects.The effects of different environmental temperatures and hu-midity on fertility rate,litter size per litter,survival rate of newborn litter,weight of newborn rabbits,and weight of 30 day old weaned rabbits were monitored and compared.Result The results showed that the conception rate,litter size per litter,survival rate of newborn litter,and weight of weaned rabbits in the normothermic group were signifi-cantly higher than those in the high-temperature and low-temperature groups,with statistical significance(P<0.05).The conception rate,litter size per litter,survival rate of newborn litter,and weight of weaned rabbits in the constant humidity group were significantly higher than those in the high humidity group and low humidity group,with statistical significance(P<0.05).The conclusion of this study is that when the temperature and humidity of the external environment change,it can have a significant impact on the litter performance of rabbits.Among them,normal temperature and humidity can significantly promote the litter performance of rabbits in the local ar-ea.This provides a scientific reference value for finding the appropriate optimal environmental temperature and humidity for rabbit breeding in the local area,and also for improving and promoting the efficiency of rabbit breed-ing.
