First, mating wild boar generally can produce 2 to 2.5 fetuses per year, 8 to 16 per fetus, mating time to 6 to 7 months of age, weight 60 to 70 kg is appropriate. Since wild boars have higher IQ and sensitivity than normal domestic pigs, they cannot be used for cross-breeding, false vaginal or freehand picking. Only natural mating methods can be used. Breeding occurs when the gild of the sow allows the boar to cross. Normal breeding is effective within 12 to 24 hours after estrus is allowed and allowed to climb. The female wild boar can be managed to climb comfortably, or the vulva changes from bright red to dark purple, changes from swollen to slightly shriveled, or the mating member presses the hindquarters of the pig by hand and stands still, which is a suitable breeding time. The first time after the interval of 6 to 8 hours and then repeated once to increase the conception rate. Before mating, the sundries in the female wild boar enclosures should be carried out to prevent injury to pig legs or accidents. At the same time, the female wild boar genital area was scrubbed with 3% potassium permanganate solution and then placed in a breeding boar for breeding (about 30 minutes during the breeding process). Allow 1 hour for breeding after drinking. If it is confirmed that the female wild boar has been bred, the amitraz solution should be rubbed on the whole body for 2 to 3 times to kill the body surface parasites so as to prevent the female wild boar from scratching and causing pregnancy abortion.
Second, the production
1. Preparation before giving birth The wild boar is injected with E. coli vaccine about 20 days before the onset of labor, or long-acting antibiotics are injected intramuscularly for 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, pave 1000 mat grass, install a drinking trough, electric lights, add enough water in the tank, prepare the farrowing box (warm and warm seasons should be prepared in winter and spring cold season), iodine, deesterified cotton balls, cable tie And sterilized scissors and other items, and there is a dedicated person on duty to prevent accidental birth of the female wild boar piglets.
2. Concern for production confinement Female boars usually have a gestational period of about 114 days. Before they reach the stage of production, they start to hold grass, frequent urination, irregular defecation sites, swelling of the vulva, rapid respiratory rate, and unwillingness to stand. 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. Boars stand up once they are born 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.
Each time the female wild boar was born, the confinement workers picked up and wiped the blood stains and stickies in the mouth of the pigs with a 3% potassium permanganate solution. After leaving the umbilical cord at 4 to 5 cm in length, cut it off, 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. After production, the norfloxacin is transferred into a paste and put into the pig's tongue base for swallowing to prevent hemolytic leukoplakia and edema-type E. coli and other intestinal diseases. After 20 days of age, piglets should be vaccinated. At the age of 60 days, pigs should be given intramuscular injections of “triple seedlingsâ€.
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 timely replaced with short straws and other clean straw. The 3% potassium permanganate solution should be used to wipe the sow's teat and both sides. An intramuscular injection of 3.2 to 4 million units of penicillin in the neck of the female boar was repeated for two days, two times a day (each interval of 8 to 12 hours) 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.
