How to Handle Uterine Bleeding and Uterine Prolapse in Sows
Uterine prolapse is mostly seen during abortion and in the hours before and after farrowing and throughout the whole process. To prevent uterine prolapse, strengthen feeding management in daily practice, pay attention to exercise and calcium supplementation, and keep the floor of the pig house at an appropriate slope. If uterine prolapse is found, carry out reduction promptly. For incomplete uterine prolapse, the operator should thoroughly wash and disinfect the hands and arms, apply an oil-based lubricant, then reach into the vagina, keep the sow in a position with the front high and the rear low, and carefully push and press the uterine horn. If it cannot be fully corrected, 500-1000 ML of 0.1% potassium permanganate or normal saline can be injected into the uterine cavity, and the pressure of the fluid can help restore the uterus.
For complete uterine prolapse, first carry out local treatment of the prolapsed uterus: first remove the feces attached to the mucosa, wash with 0.1% potassium permanganate solution or 1% salt water, place it on a disinfected cloth, and check the uterus for torsion or laceration. If a blood vessel is ruptured, ligate it. For severe edema, wash with 3% alum water. During reduction, two people lift the uterus to the same height as the vagina, and one person performs the reduction. The left hand holds the uterine horn, and the right thumb performs the reduction starting from the end of the uterine horn. Then form the hand into a cone shape and, just like turning intestines back, push hard while the pig is not straining, turning it inward in sequence. In this way, push the two uterine horns into the uterine body one after the other, and at the same time push the uterine body into the pelvic cavity and abdominal cavity. After the reduction is complete, suture the vulva with two stitches of thick silk thread to prevent prolapse from recurring. Note that anesthesia is needed when necessary. After reduction, inject antibacterial drugs to reduce inflammation.
