批次化生产提升母猪繁殖效率的实践探索
Practical exploration of batch production to improve reproduction efficiency in sows
摘要
Abstract
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.关键词
