不同繁育饲养设施对Beagle犬生产性能的影响

Comparison of the Performance of Beagle Dogs Bred in Two Kinds of Breeding Houses

目的探索不同繁育饲养设施对Beagle犬主要生产性能的影响。方法使用两种不同Beagle犬繁育饲养设施(设施Ⅰ、设施Ⅱ)对母犬产仔状况、仔犬初生重、60 d离乳犬只存活率、60 d离乳犬只体重、1～6月龄犬只体重月增长等生产性能进行了比较研究。结果两种设施比较母犬产仔状况,仔犬初生重无差异(P>0.05);设施Ⅱ比设施Ⅰ的60 d离乳犬只存活率高18.4%,差异极显著(P<0.01),60日龄离乳犬只体重平均多(0.62±0.13)kg,差异极显著(P<0.01);1～6月龄犬只体重月增长平均多0.29±0.14 kg,差异近显著(P=0.08>0.05)。结论设施Ⅱ优于设施Ⅰ。

Objective To analyze the performance of Beagle dogs bred in two kinds of breeding houses.Methods Performance of Beagle dogs bred in different breeding houses（house Ⅰ and house Ⅱ） such as litter situation,birth weight,survival rate and body weight of weaning dogs 60-days old,and weight gain per month was compared.Results The birth weights of Beagle dogs bred in house Ⅰ and house Ⅱ were statistically not significant different（P 0.05）,while the survival rate of weaning dogs 60 days old bred in house Ⅱ was 18.4% higher than that in house Ⅰ（P 0.01） and the weight of weaning dogs 60-day old bred in house Ⅱ was 0.62 ± 0.13 kg higher than that in house Ⅰ（P 0.01）,as well as weight gain per month of the dogs bred in house Ⅱ was 0.29 ± 0.14 kg higher than that in house Ⅰ（P = 0.08 0.05）.Conclusion The House Ⅱ is better than house Ⅰ.
