Key Technical Points and Methods for the Prevention and Treatment of Swine Obstetric Diseases
The main obstetric diseases of pigs include infertility, abortion, gestational edema, fetal death in utero, dystocia, vaginal prolapse, retained placenta, endometritis, farrowing paralysis and non-infectious reproductive disorders of sows. Such diseases are a series of conditions that arise after adult breeding sows have mated with breeding boars. Each obstetric disease has its own specific cause, so the causative factors must be ruled out one by one and treatment must be targeted accordingly to achieve results.
However, disease is by no means caused by a single factor, so to prevent and treat swine obstetric diseases, comprehensive prevention and treatment measures must be adopted as the focus.
①The selected breeding boars and sows must both be in good health, free of disease and especially free of congenital reproductive organ diseases; this is the most important and most fundamental point.
②Feed formulation must be scientific and reasonable, with comprehensive nutrition, to maintain the healthy constitution of the breeding pigs and meet their various nutritional needs; none of these can be omitted.
③Strengthen management and provide regular exercise to maintain a strong physique in the breeding pigs.
④Master scientific breeding techniques to increase the fertilization rate and vitality of the fertilized egg and promote normal and healthy fetal development.
⑤Provide good pre-farrowing and post-farrowing care, carry out strict disinfection, and promptly and carefully solve any problems found, so as to prevent birth canal injury and postpartum infection.
⑥During treatment, select the corresponding sensitive drugs according to the condition to improve the therapeutic effect. Treatment must both target the symptoms and take comprehensive factors into consideration, with particular attention to fluid replacement. Because sows are weak after farrowing and are in the recovery period, the drugs can be mixed into normal saline or glucose saline during treatment for a better effect.
