摘　　要：为了研究不同月份德国牧羊犬母犬的繁殖规律,试验收集江西某犬场2013年3月份-2017年2月份德国牧羊犬母犬繁殖记录,采用方差分析比较不同月份德国牧羊犬母犬发情、受胎及产仔性状的规律。结果表明:德国牧羊犬母犬全年均可发情,每年6月份及11月份出现发情小高峰;配种月份对母犬受胎率影响较大,4月份、11月份受胎率显著高于7月份、8月份(P<0.05);平均窝产仔数为(5.68±0.30)只,其中5月份显著高于9月份、10月份(P<0.05);2月龄仔犬平均成活率为71%,11月份出生的2月龄仔犬成活率显著高于7月份(P<0.05)。说明不同月份德国牧羊犬繁殖性状差异较大,4月份、11月份母犬的受胎率以及11月份出生的2月龄仔犬成活率均优于其他月份。In order to study the reproductive performance of German shepherd bitches in different months,breeding information were collected from one kennel in Jiangxi province from March 2013 to February 2017.Estrus,Pregnancy rate and puppies data were collected and analyzed by ANOVA.The results showed that the German shepherd dogs might be in estrus all year round with two peaks of wave in June and in November.Mating month also had influence on the pregnancy rate,with the two peaks of wave in April and November,which were significant higher than that in July and August (P<0.05).The average litter size of German shepherd dogs is 5.68±0.30,and it was significant higher in May than that in September and October (P<0.05).Until to 2 months,the survival rate of the pups was 71%,and it was significantly higher in November than that in July (P<0.05).In conclusion,the reproductive parameters varies in different months in German shepherd dog,while the pregnancy rate and survival rate in April.andNovember were better than other months.
