Clinical symptoms of postpartum fever in sows
The clinical symptoms are: elevated body temperature, 40.5°C~41.5°C, preference for lying down, reduced appetite or no eating, body trembling, rapid breathing, reduced milk production, and purulent discharge flowing from the vulva.
Postpartum fever in sows:treatedmethods
Treatmentshould be started early. According to body temperature, appetite and spirit, differenttreatmentmethods should be used for mild and severe cases. Mild cases: body temperature around 40.5°C, no eating, spirit still acceptable. Mix 1.2 million units of penicillin and 1.5 grams of streptomycin for intramuscular injection, 2 times a day, for 2~3 consecutive days; intramuscular injection of 20~40 units of posterior pituitary extract, 1~2 times a day, for 2~3 consecutive days. Severe cases: body temperature above 41°C, depressed spirit, preference for lying down, no eating, shivering, relatively heavy lochia. Use 10~20% caffeine sodium benzoate 10 milliliters, subcutaneous injection: 1~1.5 grams of tetracycline hydrochloride, dissolved in 500 milliliters of 5% glucose saline for one intravenous injection; intramuscular injection of 20~40 units of posterior pituitary extract. The above three medicines are given 1~2 times a day, for 2~3 consecutive days.
Prevention of postpartum fever in sows
1. One week before farrowing, thoroughly disinfect the farrowing shed and equipment with 2% caustic soda solution or formaldehyde solution.
2. The sow should gradually have its feed reduced before farrowing, and should not be fed for the meal immediately before farrowing; this helps with a smooth delivery.
3. Before and after farrowing, wash the sow's vulva and udder with 0.1% potassium permanganate solution.
4. If farrowing difficulty occurs, use 20~40 units of posterior pituitary extract for intramuscular injection to induce labor. Try not to insert hands into the birth canal to grope around. If it is absolutely necessary to do so, the operator's arms should be washed clean with 0.1% potassium permanganate solution, then coated with sulfonamide ointment to prevent infection of the birth canal.
5. Within 1~3 days after farrowing, closely observe changes in spirit, appetite, milk production, body temperature and so on. When farrowing occurs in hot seasons, after the birthing process ends, use sulfonamide drugs and posterior pituitary extract to prevent postpartum fever; the effect is obvious.
If bleeding occurs during sow farrowing, in addition to doing a good job of stopping the bleeding, disinfection work must also be done well. If assistance in delivery is needed, preparations must be made and operations carried out carefully, trying not to injure the birth canal. Only in this way can the occurrence of postpartum fever in sows be avoided.
