There is a problem
Early surgery Some pig farmers mistakenly believe that the sooner the piglets are castrated, the better. Even some pigs will die without a full moon, which poses a great risk. In fact, it is not good for piglets to castrate too early or late. Generally, they are selected 15-30 days after weaning. If it is prematurely castrated, due to its immature muscles, abdominal organs such as the intestine and the bladder will emerge from muscles that are not suitable for healing. Caused by various kinds of subcutaneous sac, severe cases will appear intestinal necrosis, the formation of collapse, long died.
Preparation is not in place. Preoperative observation of castrated pigs is very important. The spirit, body temperature, respiration, defecation, hunger, etc. of piglets should be carefully observed before surgery. Once these problems are ignored, errors often occur, resulting in postoperative conditions. Increase. Also, the sows should stop feeding before they are castrated, which is very beneficial for the smooth operation and wound healing. In addition, the castrated pigs should avoid the hot and cold weather, and it is best to choose a mild and windless weather.
Problems that are easy to be neglected The surgeon's hands are first washed repeatedly with a disinfectant soap or soap and then disinfected once with 5% iodine and 75% alcohol. The surgical tools and needlework must be disinfected before surgery and usually boiled for 15 minutes. The surgical department of the piglet must use 5% iodine and 75% alcohol to disinfect the incision site. Tetanus vaccination should be given before the piglet surgery. In addition, freshly-swept pigs should be gently rushed to the slow walking state, do not let the side of the knife to sleep in the following, to prevent infection or destruction of the seal caused by inflammation. Cleanliness and disinfection should be done well in advance and outside the farm.
Avoid mistakes
The first is that the gilt sows do not castrate. The estrus's sows have less obvious morphological features and are prone to mistakes. Once castrated, they cause more bleeding and even death. Therefore, we must pay attention to observation and carefully determine the pigs who are going to castration surgery. Followed by satiety pigs bogey cut. Some pig farms did not separate the hungry food from the piglets that were to be castrated. Instead, they let the entire circle of pigs stop for a meal. This did not achieve the effect of stopping the feeding before surgery. Some hungry pigs had already taken food. The remaining troughs and foods are full, so that the uterus and ovaries of the gilts are not easy to extrude incisions at the time of surgery, which can easily cause rupture of the intestines, and can easily damage the gastrointestinal tract and affect the digestion, absorption, and growth of the pigs. In addition, pigs that have just been purchased are avoided. Due to changes in the environment and changes in feed, surgery on freshly purchased pigs can easily cause unimaginable stress and even acute death. Therefore, piglets that have just been relocated from the field must wait at least 10 days before they can choose the timing of the cutting.
Prevention of castration complications
Intraperitoneal mouth inflammation at the first glance showed good healing, but when inspected, it was slightly red and swollen. When the pig's abdominal wall was touched, the pig had only a painful feeling, and the body temperature increased, the spirit was depressed, the diet decreased, and the body quickly lost weight. The main reason is that peritonitis can be caused by lax disinfection during surgery or incomplete disinfection, long operation time or poor hygiene. In the treatment, the heat-applying abdomen with lesser symptoms causes adhesions to dissipate; for those who are found to be late and have severe symptoms, the abdominal wall can be dissected and the adhesion part between the abdominal wall and the intestine can be separated. After the incision is washed with antiseptic syrup, the anti-inflammatory drugs are scattered, and then continuously Intramuscular antibiotics such as penicillin for 3-5 days.
Bleeding at the edge of the knife When cutting the sow, the incision is too large and the force is excessive. The knife penetrates into the deep and causes injury to the external iliac artery, internal iliac artery, and other veins, causing intra-abdominal bleeding and external hemorrhage; spermatic cord broken and vas deferens during the operation of the boar. Inaccurate hemostasis, inappropriate force during surgery to rupture the spermatic blood vessels, scrotal wall blood vessels; hemorrhagic diathesis. Preventive measures: surgical site (including spermatic cord), thicker vessels of the internal genitalia must be sutured firmly through the ligature; if bleeding occurs, some cold water may be splashed at the waist; intramuscular injection of blood and vitamin K3, etc. may be necessary for severe bleeding; When the scrotum cavity can be filled with sterile gauze, scrotal skin wounds made several stitches of temporary suture, 24-48 hours after removal of sutures and gauze.
Most of the tetanus diseases are caused by severe disinfection of cutting edges and surgical instruments during castration. Clostridium tetanus infections occur through wound infections, and the reaction of the sports center to external stimuli increases, and muscles continue to contract as a characteristic disease. The first treatment was repeated with 3% hydrogen peroxide solution, followed by disinfection with 5% iodine, and antibiotic ointment; with chlorpromazine 50-100-mg intramuscular injection, a deep injection of 800-1.6 million units of penicillin around the operation site; Herbs are treated with anti-wind loosening and detoxification.
API (Active Pharmaceutical Ingredient) refers to a substance or substance combination used in manufacturing a drug product. API also refers to the active or central ingredient in the product which causes the direct effect on the disease diagnosis, prevention, treatment or cure. While API is the active component of a drug, excipients are the inactive or inert substances present in a drug.
An API starting material, usually a defined chemical property purchased in the market place or produced in-house, is used in the production of an API.
