The female wild boar has estrus performance (no food, no sleep, arched door, no call, no swelling, no swelling, etc.), but after the boar enters the sow ring, the sow not only does not allow it to climb, but also bites the public pig. . In this way, breeding is difficult to succeed. The main reason for this is: 1 female wild boar suffering from metritis or chronic metritis; 2 female wild boar endocrine deficiency. The prevention measures are as follows:

Prevention After the female wild boar has finished birth and discharged the placenta, it immediately injected 3.2 million units of penicillin twice a day for 3 days, and thoroughly disinfected and replaced the bedding with a hundred poisons to prevent the female uterus from being infected. 2. Add sulfa drugs in the feed according to the bottle label instructions, and feed for 3 days.

Treatment of swine disease For female wild boars with metritis or chronic metritis, 10 mg of diethylstilbestrol is intramuscularly injected to open the closed cervix and inject once every 3 days. Thereafter, intramuscular injection of oxytocin (oxytocin) 2 (2 ml), the uterus produces a rhythmic contraction and discharges purulent exudate, injected once every 2 days, and then mixed with injection of cyan, streptomycin or sulfonamide Sodium pyrimidine, which eliminates uterine inflammation.

2. Add 50% glucose 20cc × 2 to add penicillin sodium 800,000 × 4 mixed, then inject 400 cc of compound sodium chloride dilution solution, and then slowly push into the female wild boar uterus with a 40-50 ml syringe (with a rubber vas deferens). . After 30 minutes, the boars were rushed into the female wild boar enclosure. At this time, the female wild boar generally allowed the boars to climb across to achieve the purpose of breeding.

3. Injection of estrogen. Insufficient endocrine (estrogen) in female wild boars will not accept breeding boars. If this happens, the female wild boar can be intramuscularly injected with 4 estradiol benzoate (2 mg each) in the neck of the female wild boar, usually on the 2nd or 3rd day of the estrus of the female wild boar. The breeding was successful.
