Clinical manifestations of postpartum metritis in sows;
Acute type: sick pigs lose appetite or stop eating, their body temperature rises, their noses are dry, their backs are often hunched, and they urinate frequently. Sometimes there are gray-white or gray-yellow dirty secretions from the vulva, and sometimes there are fetal fragments, especially when they lie down, their lactation is reduced, and they refuse to breastfeed piglets.
Chronic type: This type is more common. Sick pigs will have a slight systemic reaction, loss of appetite, but increased appetite, elevated body temperature, dry nose, decreased urination and red and yellow urine. Sows mainly have sticky secretions around vulva and tail roots, which give off a foul smell. After drying, it will form a thin scab with various colors, such as white, light gray, dark gray and yellow. And generally, when you stand, you won't shed mucus, but when you lie on the ground, you will shed more and lose weight gradually.
Recessive type: sick pigs usually do not show obvious systemic symptoms. When the appetite is jet lag, the estrus cycle is abnormal and irregular, and repeated infertility often occurs. When washing the uterus, there will be a slightly turbid, nose-clearing liquid reflux.
It is generally difficult to treat sow metritis because there are many folds in the inner wall of sow uterus, the environment is relatively closed and inflammation is difficult to eliminate. If the treatment is simple, it is often difficult to work. Therefore, sow metritis is often supplemented by prevention and treatment.
Ensure environmental sanitation
The pigsty must be clean and hygienic, and the delivery room must be strictly disinfected before the pregnant sow is transferred to the delivery room.
Before sows give birth, they should use 0. 1% potassium permanganate solution to scrub vulva, breast, tail and parts near the limit fence.
Appropriate midwifery measures should be taken during delivery to avoid damaging the mucosa of the birth canal, especially when dystocia occurs and manual midwifery is needed. Before midwifery, hands and other utensils should be soaked and disinfected with 0. 1% bromogeramine or 0.05% disinfectant.
After the fetus is delivered and the placenta is discharged, the birth canal can be washed with disinfectant with appropriate concentration and appropriate antibacterial drugs can be infused. Clean up the feces on the delivery bed in time, and do it twice a day, otherwise it will lead to the infection of streptococcus and Escherichia coli in the feces of the delivery canal, especially after delivery 1 week. Because of weak body, lochia is being discharged, so it is necessary to strengthen nursing.
medicine
Drug treatment: During the treatment, it should be noted that uterine lavage is prohibited for sick pigs with obvious systemic symptoms, because most of these sick pigs will lead to rapid deterioration and even death after uterine lavage. If the sick pig does not show systemic symptoms or has no obvious systemic symptoms, the uterus can be washed. Generally speaking, when there are many inflammatory secretions in the birth canal of sick pigs and the color is dark, uterine irrigation can be carried out, but attention should be paid to the operation to avoid mechanical trauma caused by being too rough. Rinse with 0. 1% potassium permanganate solution. After washing, antibiotics or metronidazole suspension were injected into the uterus, and 10% glucose saline, 2g ceftiofur and vitamins were used for infusion treatment to avoid secondary infection. You can also choose the traditional Chinese medicine "Achyranthes powder" for treatment, including 30 grams of Achyranthes bidentata, 30 grams of Carthamus tinctorius, 40 grams of Angelica sinensis, 30 grams of Cinnamomum cassia, 24 grams of Radix Aconiti Lateralis Preparata and 24 grams of Rhizoma Zingiberis Preparata, which are decocted in water.
