TECHNICAL FIELD
[0001] The utility model relates to sow production technical field, concretely is a sow production midwifery apparatus. BACKGROUND
[0002] In large-scale pig farms, the main reason for sow dystocia is that there are multiple piglets in the uterus of the sow to be born at the same time. In the early stage of production, multiple piglets can cause the sow's birth canal to be prone to transverse position and other conditions, resulting in stillbirth and blocking the sow's birth canal, which can lead to sow dystocia. In addition, factors such as dystocia caused by narrow birth canal, weak birth force, bladder urine accumulation, and stress caused by external stimulation can also cause sow dystocia. In addition, sow dystocia can also be caused by excessive obesity, birth canal deformity, disease or developmental disorders. Therefore, a sow production midwifery apparatus is needed.
[0003] However, the existing sow production midwifery apparatus has the following shortcomings:
[0004] (1) The existing sow production midwifery apparatus has weak sow health protection function. During sow production, stillbirth can block the birth canal, causing sow production difficulties, sow inflammation, and reducing sow health and service life.
[0005] (2) The existing sow production midwifery apparatus has weak function of fitting the sow's birth canal inner wall. During midwifery, due to different degrees of sow birth canal narrowness, the traditional midwifery apparatus is difficult to fit the birth canal inner wall after entering the sow's birth canal, causing operation difficulty and reducing sow midwifery efficiency.
