摘要
以母猪的配种、分娩季节为研究对象,应用单因素方差分析和多重比较等统计方法对21 3321条配种记录和160545条分娩记录进行分析,以探索季节性差异对基础母猪群繁殖成绩的影响。研究结果表明,冬季配种的母猪分娩率和窝产总仔数最高,分别为76.51%和10.66头,且极显著高于春、夏两季配种母猪的(P<0.01);其中冬季配种杜洛克、大白母猪和秋季配种长白母猪的窝产总仔数为同品种配种季节对比中最高,分别为9.85头、10.92头和10.52头。另外,春季分娩的母猪窝产总仔数为1 0.65头,窝产活仔数为9.44头,均极显著高于其他分娩季节(P<0.01);其中春季分娩杜洛克、长白、大白母猪窝产总仔数为同品种分娩季节对比中最高,分别为9.75头、1 0.62头、10.92头。因此,杜洛克和大白母猪在冬季配种时表现的繁殖性能最佳,长白母猪在秋季配种时可获得最优的繁殖成绩;妊娠阶段在气候温和的冬-春季,分娩时间在春季的母猪产仔性能更好。
The One-Way ANOVA and LSD test were used to analyse 213321 strip of mating records and160545 strip of farrowing records for studying the effect ofseasonal variationson sows reproductive performance.These study resultshad the following:Firstly,sows mating in winter had 76.51%farrowing rate and 10.66 heads litter size.It was significantly higher than that of spring and summer mating seasons(P<0.01).In comparison to the same breed,the Duroc and Yorkshire sows litter size of mating in winter were 9.85 and 10.92,the Landrace sows litter size of mating in autumnwas 10.52.These were the highest contrast in different mating season.Secondly,the total bom litter size in spring was 10.65,and the total number of live-born piglets was 9.44.These items were significantly higher than that of the other farrowing seasons(P<0.01).In comparison to the same breed,the Duroc and Landrace and Yorkshire sows litter size of farrowing in springwere 9.75,10.62 and 10.92.These were the highest contrast in different mating season.Therefore,the Duroc and Yorkshire sows mating in winter showed the best reproductive performance,and the Landrace sows reproductive performance of mating in autumn wasbetter than other seasons.Besides,the farrowing time in spring had higherlitter size.
