Analysis on the Ways to Improve Sow Production Technology in Dongkou County

2017年洞口县畜牧水产局调查母猪养殖户101户繁殖母猪365头693窝，头年均产仔窝数1.89胎，窝平产活仔9.05头，仔猪成活率88.2%，育成率90.3%。而湖南省新五丰的猪场母猪头年均产仔窝数2.29窝，窝平产活仔11.9头，仔猪成活率90.6%，育成率93.5%，这四项指标,洞口县分别降低17.5、22.3、2.4、3.2个百分点。洞口县PSY数13.85头，为集团猪场PSY数26.8头的51.7%。本文从后备母猪生产、母猪饲料营养、母猪保健和补乳、母猪疫苗免疫接种和疫病防治、减少母猪应激、淘汰低能繁殖母猪、母猪科学养殖新技术、母猪生产档案管理等途径来提高母猪生产水平。供猪业同行参考。In 2017, the Animal Husbandry and Aquaculture Bureau of Dongkou County investigated 101 sow breeders who bred 365 sows in 693 litters. The average litter size in the first year was 1.89, with 9.05 live piglets per litter. The survival rate of piglets was 88.2%, and the breeding rate was 90.3%. In the pig farm of Xinwufeng, Hunan Province, the average number of litters per sow in the first year was 2.29, with 11.9 live piglets per litter. The survival rate of piglets was 90.6%, and the breeding rate was 93.5%. These four indicators decreased by 17.5, 22.3, 2.4, and 3.2 percentage points respectively in Dongkou County. The number of PSY in Dongkou County is 13.85, which is 51.7% of the 26.8 PSY in the group’s pig farm. This article aims to improve the production level of sows through various approaches, including the production of reserve sows, nutrition of sow feed, sow health and lactation, sow vaccine immunization and disease prevention, reducing sow stress, eliminating low-energy breeding sows, new technologies for scientific breeding of sows, and management of sow production records. For reference by peers in the pig industry.
