What causes pus discharge 10 days after a sow is mated
Problems can arise during the mating process of sows, and only when mating is successful and the sow herself is healthy can healthy piglets be bred. What causes pus discharge 10 days after a sow is mated? How should it be prevented and treated?
1. Causes of pus discharge 10 days after a sow is mated
There are two situations for pus discharge after a sow is mated. Pus discharge occurring some time after mating is because the sow contracted metritis during the mating process, and pus tends to flow out when the cervix opens in the next estrus; pus discharge occurring very soon after mating is because the sow had already contracted metritis early on, the inflammation was relatively severe, and the pus was too viscous to flow out. After mating, the semen diluted it, and at this point the pus was no longer viscous and flowed out.
2. How to prevent and treat sow metritis
1. Strengthen disinfection of the farrowing house and of the sow's udder and hindquarters before and after farrowing, keep the farrowing house clean and dry, and reduce the number of pathogens on the sow's body surface and in the environment to a minimum.
2. To prevent reproductive tract infection and metritis in sows, an intravenous drip should be given to the sow within 8 hours after farrowing or after the first piglet is born, which can effectively prevent infection of the reproductive tract and uterus by various bacteria.
3. Pus discharge 10 days after a sow is mated means she has metritis. Cloprostenol can be injected intramuscularly, then the uterus can be flushed with Gongjingkang, once a day for three consecutive days. Then inject ceftiofur sodium plus Houttuynia cordata, also once a day for three consecutive days. As for feed, add tocopherol, mold remover, multivitamins, and Yimu Shenghua San, and feed continuously for one week.
3. Causes of sow metritis
1. During farrowing, the sow's vagina is damaged and immunity is reduced, so pathogens can easily invade the sow's body through the vagina, produce toxins, and thereby infect the sow with endometritis.
2. Diseases such as parvovirus, porcine reproductive and respiratory syndrome, swine fever, Japanese encephalitis, and pseudorabies infect the sow and secondarily cause endometritis.
3. Disinfection during artificial insemination is not thorough and the technique is not skilled enough; during mating, the reproductive tract is easily mechanically damaged; during copulation, the boar carries inflammatory secretions.
4. Improper feeding management, such as feeding moldy feed to sows, causes mold poisoning and infection, resulting in low immunity in sows, making them susceptible to infection. Pig house hygiene is not cleaned in time, disinfection is not thorough, and the afterbirth of stillborn piglets and miscarriages are not handled properly.
5. During difficult farrowing, retained afterbirth causes uterine atony and retention of lochia; vaginal and uterine prolapse and other conditions damage the sow's reproductive tract and cause infection with this disease.
In short, to prevent sows from developing inflammation, hygiene and disinfection work in the pig house should be done well, and inflammation can also be prevented with medicated solutions.
