Three methods of breeding and breeding sows

The breeding season should allow breeding sows to give birth during the spring and autumn season when the temperature is appropriate. Both of the two production seasons are the best seasons for rearing pigs, and they are also the best breeding season for sows after weaning, which will help improve the conception rate and the number of births. The growth and development of pigs is good. Of course, large and medium-sized pig farms with good delivery room facilities may also try to produce their sons all year round in order to improve reproductive performance.
Inducing estrus to allow pigs to estrus on schedule, ovulate, and timely breeding, abortion, is the key to ensuring normal breeding and raising the number of births. For estrus disorders caused by endocrine disorders or other factors, "tristimulus hormones" may be used for aphrodisiac. The method is: For sows that have been weaned for more than 5 days after weaning, an intramuscular injection of 2 ml of triple hormone can achieve the purpose of promoting estrus, ovulation, and timely breeding.
Postpartum arthritis using a single sow postpartum mastitis, metritis, vaginitis, postpartum fever and other perinatal diseases, some secondary pneumonia, causing death. In order to prevent the morbidity of the puerperal period, sow prevention measures can be taken quickly after giving birth. The method is: After giving birth (within 12 hours after childbirth), use 10 ml of aminopyrine, 2 million units of penicillin, and 1 million units of streptomycin, mix well, and place an intramuscular injection 2 cm to 3 cm behind the ear of the sow's neck. It is very effective in preventing the above-mentioned four perinatal diseases, and can avoid death caused by secondary pneumonia.
