About 30 days before boar production, E. coli vaccine was intramuscularly injected or long-acting antibiotics were injected intramuscularly 3 days before delivery. At the same time, clean and rinse the barn thoroughly and disinfect it with Suer or potassium permanganate solution. After the cement floor is dry, put it on dry mat grass, install a drinking trough, electric light, add enough fresh water in the tank, prepare the farrowing box (we should keep the warm box in the winter and spring cold season), iodine, deesterified cotton balls, and cable And sterilized scissors and other items, and there is a dedicated person on duty to prevent accidental birth of the female wild boar piglets.
Second, the production of matters needing attention
1. Female boar gestation period is generally about 114 days, began to give priority to grass before childbirth, frequent urination, irregular defecation site, pus, redness, increased respiratory rate, do not want to stand, etc., indicate that the imminent birth. Most sows have successfully laid piglets after laying grass on the side. Domestic pigs are first-in-first-out, and wild-type pigs are first-in-first-out.
2. Once wild boars have been raised, they will stand up and begin to milk. If there is too much calving and there is not enough teat, you may adopt batch feeding or other foster mothers who are close to farrowing and have less calving. However, the phenomenon of lack of milk in the mother wild boar after giving birth is rare.
3. Each time the female wild boar is born, the confinement workers pick up and wipe the systemic bloodstains and stickies in the mouth with a towel soaked in 3% potassium permanganate solution. After leaving the umbilical cord in a 4-5 cm ligatures, cut the umbilical cord, apply iodine tincture at the cut-off point, cut off two canine teeth on both sides of the oral cavity, and put the piglet in the litter box that has been prepared.
4. After production, make norfloxacin into a paste and put it into the pig's tongue to swallow it to prevent hemolytic leukoplakia and edema E. coli and other intestinal diseases.
5. When the female wild boars are all discharged from the placenta, the original bedding and bloodstains should be removed. The ground should be disinfected and immediately replaced with a short cut of clean straw and other litter, and wipe the sow's teat and both sides with 3% potassium permanganate solution. At present, 3.2 to 4 million penicillin units are intramuscularly injected into the neck of female wild boars for two days, two times a day (8-12 hours apart) to prevent high fever and uterine inflammation in the female wild boar. The piglet was then placed in a female wild boar hall to allow it to freely suck milk, feeding once every 4 hours for 4 consecutive days to prevent the piglet from being crushed by the female wild boar. Afterwards, the color and mental status of the piglet and sow should be observed, so that early treatment of the disease can be detected early to ensure that piglets and mother wild boars grow in a healthy manner and raise their breeding efficiency.
6. After 20 days of piglets, piglets should be injected with vaccines. At the age of 60 days, pigs should be injected with triple vaccine.
Raising the survival rate of boar calving and re-production
First, the preparation before giving birth
