摘　　要：为探讨批次化生产对母猪繁殖效率的影响,试验采集了2个规模猪场批次化转型前后各3年的繁殖生产数据,对比分析年均基础母猪存栏、年均配种母猪数、年均分娩母猪数、配种分娩率、平均窝产总仔数、平均窝产健仔数、平均窝断奶仔猪数、母猪年产胎次和母猪年均提供断奶仔猪数(PSY)。结果表明:批次化转型后在保持产房满负荷运行的前提下,两个猪场的年均基础母猪存栏极显著减少(P<0.01),但年均配种和分娩母猪数、窝产总仔数均显著增加(P<0.05或P<0.01),平均窝产健仔数、平均窝断奶仔猪数显著增加(P<0.05)或呈现增加趋势(P>0.05),母猪年产胎次和PSY均极显著增加(P<0.01)。说明科学合理地实施母猪批次化生产,能有效提升猪场繁殖生产水平和盈利能力,促进养猪业节本增效。To explore the influence of batch production on reproduction efficiency in sow,the reproductive production data of two large-scale pig farms were collected for a period of 3 years before and after batch production.Comparative analyses were conducted on the average annual basic sow herds,the number of breeding sows and farrowing sows per year,the farrowing rate of breeding sows,the average total litter size,the average healthy litter size,the average number of weaned piglets per litter,the annual parity of sows,and pigs weaned per sow per year(PSY).The results indicated that after transforming into batch production,while maintaining the farrowing room at full capacity,the average annual basic sow herds of the two farms was extremely reduced(P<0.01).The annual number of breeding and farrowing sows and litters size were extremely increased(P<0.05 or P<0.01),and the average number of healthy litters and weaned piglets in each litter were significantly increased(P<0.05)or exhibited an increasing trend(P>0.05).The annual parity and PSY were extremely enhanced(P<0.01).This research demonstrates that the scientific and rational implementation of sow batch production can effectively enhance the breeding production level and profitability of pig farms,and provide substantial support for cost reduction and efficiency improvement in the modern pig industry.
