摘要
为探讨规模化育肥猪场不同季节粪污日产生量和相关污染负荷,2018-2019年分季节采集某育肥猪养殖场粪污4次,每次选取5头平均体重为(70±1.76)kg的育肥猪单独饲养,收集24 h粪便和尿液,重复3 d,进行粪尿日产生量和相关成分测定分析。结果表明:单头育肥猪粪便和尿液日均产生量分别为(1.30±0.37)kg和(2.59±0.12)L,产粪量春、冬季显著高于夏秋两季(P<0.01),产尿量秋季显著高于其他季节(P<0.01);各季节间饲料营养差异不显著(P>0.05),粪尿中各污染物浓度受气候影响,表现出季节性差异。综上表明,该育肥猪产污系数与第一次全国污染普查华北地区育肥猪产污系数相比有了不同程度的变化,产污系数存在季节差异性并有待更新。
To explore the daily manure production and related pollution load in large-scale fattening pig farms in different seasons,the manure from a fattening pig farm,was collected four times in different seasons from 2018 to 2019.Five fattening pigs with an average body weight of 70 kg±1.76 were selected each time and raised individually.Feces and urine were collected for 24 h,and the daily output and related components of feces and urine were determined and analyzed,which repeated for 3 days.The results show the average daily fecal and urine production of single fattening pig was 1.30 kg±0.37 and 2.59 L±0.12;the fecal production in spring and winter was significantly higher than that in summer and autumn(P<0.01),and urine production in autumn was significantly higher than that in other seasons(P<0.01);there was no significant difference in feed nutrition among different seasons(P>0.05).The concentrations of pollutants in feces and urine were affected by climate,showing seasonal differences.Overall,compared with the first national pollution general survey,the pollution coefficient of fattening pigs in Shanxi Province has changed to different degrees,and the pollution coefficient has seasonal differences and needs to be updated.
