First, sow production management
1, the delivery room disinfection
After the last batch of sow piglets have been removed, the delivery room must be completely and thoroughly cleaned and disinfected. Follow these steps:
(1) Remove various items in the delivery room, including heat lamps, record books, insulation boards, etc., and clean the feces and other debris under the bed and in the dung.
(2) Rinse the ground bed with a high-pressure water gun and spill it with 2% caustic soda. Caustic soda water can not only disinfect, but also can play the role of foaming, easy to clean the feces that stick on the ground and railings, but the caustic soda water has strong corrosion effect on the iron railings, especially the railings that are not in the overall hot-dip galvanizing. Use caution when using.
(3) After caustic soda water is sprinkled for 1-2 hours, then the high pressure water gun is used to thoroughly clean the delivery room, paying particular attention to the railings and leaking floor corners. Note that the perimeter of the barracks, doors and windows, tile surfaces (ceilings), appliances, and chutes should also be meticulously cleaned.
(4) After the cleaning is completed, close the doors and windows of the delivery room, fumigate with potassium permanganate + formalin, and ensure that the delivery room is airtight when fumigated; also use a broad-spectrum disinfectant to disinfect, preferably using two different types The disinfectant is disinfected twice.
(5) The delivery room is vacant for more than 2 days, and it is ensured that the inside of the delivery room is completely dry and then transferred to the sow.
2, to be born sow management
The maternity wards were completely sterilized and vacant. After checking that there was no problem with each tap, the gilts were transferred to the delivery room one week in advance to facilitate the sow to adapt to the new environment in the delivery room and the keeper to fully prepare for various preparations. Thorough cleaning and disinfection of sows prior to transfer, especially for sows' genitals and breasts. The sow card that records the details of the sow also follows the sow into the delivery room. If there is a problem with some sows, the gestating sow breeder or technician needs to communicate these issues with the person in charge of the delivery room.
3, sows feeding
To ensure that the sow’s milk is adequate, the productivity is sufficient, and the piglet’s birth weight, the sows are required to be fed with high-quality sow feed (such as Candling sow feed 5944) for 1 month before birth, and the amount of feed reaches 3 -3.5kg daily. Prenatal restriction for 3 days and stop feeding on the day of sow giving birth, this can prevent constipation of sows and dystocia caused by uterine pressure due to gastrointestinal pressure, but ensure that sows have sufficient drinking water. Gradually raise the sow's feeding amount after delivery, and reach the maximum amount of feed 7 days after childbirth. At the same time, the keeper must wash the sow's feed trough every day to prevent the feed in the trough from becoming moldy.
4, sow health care
The farrowing is very stressful for the sow. At this time, the sow's resistance is very low. The health care of the sow can not only effectively control the number of germs in the sow, but also prevent the spread of various germs to the piglets. Onset. The specific method is as follows: 3 days before delivery, 4 days after delivery, Kangdi Baokang + Kangdifenkang is added to the sow feed.
The sows were intramuscularly injected with penicillin after delivery and used for 3 consecutive days. For farms where there is a threat of parasites, ivermectin can be given intramuscularly on the same day that the sow is transferred to the delivery room. On the day of weaning, the sow can be given an intramuscular injection of long-acting oxytetracycline or doxycycline to prevent sow mastitis.
5. Prenatal care for sows
One of the priorities for the gravidas in the delivery room is to take care of the sire, especially the sows that are on-site. The breeder checks the udder, vulva, and behavior of these sows daily. The sows are often irritated, swollen, and swollen and wet in the vagina prior to delivery, especially if the sow has milk from the last nipple and the breeder should Do a good job of preparing production.
When the sow is breaking the amniotic fluid, the breeder needs to wipe the slatted floor of the sow, breast and sow after the sow is cleaned with a 0.1% potassium permanganate solution. At the same time open the heat lamp. When the first piglet is produced, 20-30 IU of oxytocin sows can be injected into the vulva. Note that if the first piglet is not produced, oxytocin must be used with caution in order to avoid malposition of the fetus and cause rupture of the uterus.
Try to avoid midwifery during the production process, but consider midwifery if the farrowing interval exceeds 1.5 hours. Artificial midwives must use soothing water to clean the buttock and vulva of the sow. At the same time, the midwife's fingernails should be cut flat. After the finger arm is completely sterilized, a one-time midwifery glove should be worn. The production of midwives sows is recommended to use 0.1% potassium permanganate solution for two consecutive days to clean the uterus, the birth canal penicillin, streptomycin, etc. to prevent metritis and secondary infection.
Sow delivery room management measures
The delivery room is one of the most critical aspects of a farm. However, in recent years, more and more people have reported that the delivery room is increasingly difficult to raise. Serious sow dropping, uterine inflammation, estrus after weaning, poor milking of sows, diarrhea of ​​piglets and other problems are plaguing many pig farms. The reason is also varied, but as long as we can fully grasp the growth characteristics of the herd, we will be able to maintain the delivery room and get the maximum production efficiency.
