对母猪难产预防以及助产技术的研究
Research on the Prevention of Difficult Childbirth in Sows and Midwifery Techniques

经过对绥宁县内岳桃农牧有限公司等11个猪场调查，母猪难产比例约2%，造成猪场一定的经济损失。母猪难产病因有产道狭窄、胎位不正、部分胎儿个体过大、初配母猪性成熟配种、母猪体质过瘦过肥、母猪严重便秘、选育营养管理不当等，必须从源头上进行控制，针对性采取B超早期母猪怀孕以及胎儿个数诊断、对便秘母猪直肠冲洗、初配母猪体成熟配种、营养调控等预防措施，进行矫正横腹位、横背位胎位、套猪法、铁钩法、剖腹产等助产技术予以助产，减少猪场经济损失。绥宁县调查了12例剖腹产手术，成功8例，成功率67%。供同行参考。
According to the investigation of 11 pig farms, including Neiyuetao Agriculture and Animal Husbandry Co., Ltd. in Suining County, the proportion of sows with difficulty in production is about 2%, causing certain economic losses to the pig farms. The causes of difficult childbirth in sows include narrowing of the birth canal, incorrect fetal position, excessive fetal size in some individuals, sexual maturity and mating of initial sows, excessive lean and fat sows, severe constipation in sows, and improper nutrition management in breeding. It is necessary to control it from the source, and targeted measures such as early pregnancy and fetal number diagnosis by B-ultrasound in sows, rectal flushing of constipated sows, mature mating of initial sows, and nutritional regulation should be taken to correct the transverse abdominal position transversal fetal position, pig trapping method, iron hook method, cesarean section and other midwifery techniques are used to assist delivery and reduce economic losses in pig farms. Suining County investigated 12 cases of cesarean section surgery, with 8 successful cases and a success rate of 67%, for peer reference.
