摘要: 为研究不同品种、采精月份、采精月龄和采精间隔等因素对加系公猪精液品质的影响,以及品种、初次采精周龄对精液质量稳定性的影响,本研究以江西某种公猪站79头加系大白猪、长白猪、杜洛克猪种公猪为试验群体,收集2018年12月至2020年12月3 921条精液采集与精液质量数据,通过混合线性模型与方差分析探究各因素对精液量、精液密度、精子活力、总精子数及其稳定性的影响。结果显示,从不同品种对精液质量的影响来看,长白猪精液量和总精子数均高于大白猪、杜洛克猪,但杜洛克猪精液密度高于长白猪、大白猪,杜洛克猪精子活力最低;从不同月份来看,1~3月采精精液密度最高,4~6月采精精子活力最高,10~12月采精精液量和总精子数最高,精液量呈现秋冬多、春夏少的季节变化规律。公猪不同月龄采精,精液质量指标也存在差异,月龄越小精液量越低,但精液密度偏高,精子活力相对较好,在19~24月龄黄金期总精子数最高。不同采精间隔对精液质量有较大影响,采精间隔越长,精液量、精液密度、精子活力和总精子数相对较好,采精间隔为5 d时综合性能最佳,但过长的采精间隔导致精子活力降低。品种影响总精子数稳定性,长白猪、大白猪总精子数稳定性显著优于杜洛克猪(P<0.05)。本研究结果表明,品种、采精月份、采精月龄和采精间隔均会影响公猪精液质量,关注这些因素有助于公猪站制定更完善的生产计划,提高公猪利用率。

Abstract: In order to study the effects of different breeds,months,ages and interval of semen collection on semen quality of Canadian boars,and the effects of breeds and age of the first semen collection on semen quality stability,in this study,79 Canadian Large White,Landrace and Duroc boars from a boar station in Jiangxi province were selected as the experimental population.The data of semen collection and semen quality of 3 921 boars from December 2018 to December 2020 were collected.The effects of various factors on semen volume,semen concentration,sperm motility,total sperm number and stability were explored by mixed linear modelandanalysis of variance.The semen volume and total sperm number of Landrace boars were higher than those of Large White and Duroc boars,but the semen concentration of Duroc boars was higher than that of Landrace and Large White boars,and the sperm motility of Duroc boars was the lowest.In different months,the concentration of semen collected in 1 to 3 months was the highest,the motility of semen collected in 4 to 6 months was the highest,the volume of semen collected and the total number of sperm collected in 10 to 12 months were the highest,and the semen dose showed the seasonal variation of more in autumn and winter and less in spring and summer.There were also differences in semen quality traits among boars at different ages.The smaller the age was,the lower the semen volume was.However,the semen concentration was higher and the sperm motility was relatively better.The total sperm number was the highest at the best age of 19 to 24 months.The longer the interval was,the better the semen volume,semen concentration,sperm motility and total sperm number were.When the interval was 7 days,the comprehensive performance was the best,but the longer the interval was,the lower the sperm motility was.The stability of total sperm number in Landrace and Large White boars were significantly better than that in Duroc boars (P<0.05).This results showed that breed,month of sperm collection,age of sperm collection and interval of sperm collection all affected boar semen quality traits.Paying attention to these factors would help boar station to make more perfect production plan and improve the utilization rate in boars.

Key words: boars; semen qualitytraits; breed; month of semen collection; age of semen collection month; semen collection interval
