For better fattening sows, castration is required. The scutellum is also called crochet. It is mainly used for gilts from 45 days old to the first estrus, and also for sows before and after weaning and weighing about 15kg. Most suitable. The operation of the castration is to use a shackle with a hook knife shank to extend into the pelvic cavity entrance, hook out the uterine horn to pull out the ovary, and remove the ovary castration technique. First, surgical equipment and drugs The knife that casts the sow is a knife with a stalk and can also be used to castrate the boar. In addition to preparing the knives and grinding the rust and disinfection before the castration surgery, prepare the washbasin, soap, alcohol cotton, suture looper, suture or ligature with clean water. Second, Baoding mother pig The mother pig is placed on the right side of the pig and the left side is upward. The surgeon stands or sits on the back side of the pig (the height of the stool is equal to the length of the calf of the surgeon). The right foot of the operator steps on the neck of the pig, the left foot rests on the left hind limb of the pig, and the back and waist of the pig are slightly bowed (do not straighten the hind limb backwards like a large peach), or the assistant will follow the above requirements. Baoding is good. Third, the cutting part After Baoding, the edge of the tibia of the mother pig (part of the hip bone, hip bone including the humerus, ischium, pubic bone) is the line of the hypothesis of the humerus, with the left hip nodule as a point, parallel to the hypothesis of the humeral edge. Assume parallel lines, the distance between the two parallel lines is about 2cm, and about 3cm on the hypothetical parallel line starting from the hip nodules is the opening of the knives (ie, the anterior aspect of the humerus and the lower part of the hip nodule). 3cm). It is also possible to follow the method of the incision incision method of the large-flowering method, and take the junction of the upper 1/3 and the middle 1/3 of the line of the anterior knee fold corresponding to the second nod of the hip nodule. Fourth, the surgical method 1. The surgical department cuts (or shaves) and disinfects according to the routine. 2. The thumb and forefinger of the right hand of the surgeon pinch the tip of the blade, and the depth of the blade is controlled to be about 1cm. The blade edge is upward. After the blade is pierced into the skin, the blade tip is slightly moved upward and upward. The incision becomes about 1.5cm long. The size of the pig determines the size of the incision so that it can be hooked out of the uterine horn and is parallel to the line of the humerus (ie, on the hypothetical parallel line of the hip joint). 3, the surgeon uses a hook with a shank to break the peritoneum, enlarge the incision, so that the back of the knife is facing the inside of the surgeon, the blade is facing outward and the shank extends vertically into the entrance of the pelvic cavity. When the handle touches any part of the uterus, the sow's limbs are constantly swiping, struggling, and the sound is louder. At this time, the hook handle should be turned to the left direction and hooked up along the edge line of the humerus. Or the fallopian tube will be hooked out of the incision by the handle hook, and sometimes the fallopian tube umbrella is hooked out of the incision. 4, the upper uterine horn is hooked out of the incision, then pulled with your fingers, pull one side of the uterine horn to the ovary to expose the incision, and cut off the ligament under the ovary, then gently pull the other side of the uterus until the other side of the ovary, Finally, the fallopian tube is lifted and the two ovaries are suspended. The ligament is cut from the ovary and two ovaries are removed. If the piglet is castrated, it can also be cut at the uterus (uterus bifurcation), and the uterine horn, fallopian tube and ovary are removed together. The larger pigs should be ligated and then removed. Fifth, the key to successful surgery 1. The Baoding method is firmly fixed and the pig's back and waist are slightly curved into bows. The surgeon stands (or sits) on the back side of the pig. 2, the incision site should be correct, but first the Baoding posture should be correct, the two are related to each other. 3, pulling the uterine horn and ovary can not be too strong, otherwise it is easy to make the uterine horn or fallopian tube broken, the ovary into the pelvic cavity, resulting in "water pigs" (returning pigs, picking pigs, leaking flowers) Castration purposes. In order to make the pigs better fattening, both the boar and the sow need to be castrated, and the maternal meat after the castration will increase, the consumption of the feed will be reduced and the feeding cost will be reduced. Therefore, castration is inevitable for fattening pigs. Our mission: To protect the health of ear, throat and nose with medical frontier knowledge and technological innovation.
