Pig endometritis prevention and treatment
When sows are in breeding, artificial insemination, childbirth, midwifery and abortion, if they do not pay attention to hygiene or disinfection, bacteria will be brought into the uterus to cause sow reproductive infections, among which E. coli, Corynebacterium, Streptococcus, Staphylococcus, Pseudomonas aeruginosa, Proteus, etc. are numerous, leading to endometritis. Partial delivery of the birth canal or part of the placenta that remains in the uterus can also cause endometritis. If the barn is not well sanitation, or if the sow is active in a sewage stadium, bacteria may also enter the uterus through the vulva to cause inflammation.
When endometritis occurs, dark red or brown-yellow secretions flow out of the vulva's vulva, sticking around the vulva, and sometimes stinking. The sows have a lot of white or brown liquids when they urinate more than ten days after delivery. This disease makes the uterus unsuitable for sperm, eggs, and embryos to survive, so that the sow cannot become pregnant. In chronic endometritis, sick pigs generally have normal appetite or mental status. In acute endometritis, the appetite of sick pigs is reduced or eliminated, and the body temperature is 395°C-42°C.
The treatment is to inject prostaglandin F2a (PGF2a) 12 days after the estrus of the pig, and to inject PGF2a 12 days after the observation of estrus. After 2 to 3 days of estrus after each injection of PGF2a, 20-40 IU of oxytocin is intramuscularly injected to promote uterine contraction and discharge of uterine contents. Then, the uterine contents are cleaned and disinfected with disinfectant solution, and the disinfected vas deferens is instilled into the cervix. Into the uterus, inject antibacterial and anti-inflammatory drugs. Treatment with penicillin can be cured. If the onset is during postpartum lactation, it is not necessary to inject PGF2a. If the body temperature rises, intravenous or intramuscular injection of antibiotics is required. In addition, 10-25 ml of aminopyrine is injected intramuscularly twice a day for 3 consecutive days. After treatment, the sows can be bred when they are estrus.
The preventive measures are to keep the pig house clean and dry, and strictly sterilize the breeding and midwifery. After giving birth, antibiotic capsules should be placed in the uterine cavity.
Many people believe that the mushroom soup is delicious. Why do mushrooms taste so fragrant? According to He Jiguo, this is mainly because mushrooms are rich in delicious amino acids. The sources of umami in mushrooms are mainly flavorful amino acids such as glutamic acid and aspartic acid, as well as taste nucleotides such as inosinic acid and guanylic acid. These substances make mushrooms taste delicious, comparable to meat .
