1, increase fat
In the 8-14 days before the sow is fed, feeding full fat (plus 9.5%) can increase the body's energy storage, increase the birth weight of the piglet, and reduce the mortality rate when feeding the full price feed.
2, add Vc
Adding 1 gram Vc daily to the diet 1 week before the sow can reduce the umbilical cord bleeding and the piglets died during the birth. Weaned piglets can reduce piglet VB12 by adding 265 mg Vc per kg of dry feed in the artificial milk or feed. Folic acid deficiency causes symptoms such as anemia and diarrhea, which reduces death.
3, enter the delivery room in advance
In the first week before delivery, the sows moved into the farrowing house to adapt to the new environment can reduce the occurrence of accidents such as the death of the newborn piglets or death of the sow piglets due to diseases such as non-milk, metritis, and mastitis due to stress in the sows.
4, timely elimination
Eliminate slaughtered, old, weak and unresponsive sows to prevent biting and squeezing the piglets.
5, prenatal injection of oxytocin
Inject small doses of multiple injections to shorten labor and reduce mortality.
6, piglets warm and wet
When the piglets are born, they require a suitable temperature of 28-32°C. After a half months, the temperature is 15-22°C. The sows need only 6-22°C. The temperature is lower than the suitable growth temperature of the piglets or the pig house is humid. The piglets will be diarrhea and diarrhea. Cause death. Therefore, we must establish a heat preservation pig house to keep the ground dry.
7, eat foot colostrum
Colostrum contains more protein, trace elements and vitamins, and there is a large amount of r-globulin, which is the main component of the antibody. Piglets that cannot eat colostrum have poor immunity and high mortality rate, so we must guarantee that every one Piglets can eat colostrum early.
8, pay attention to iron
Piglets are given an intramuscular injection of 200 mg of iron after 1-3 days of age to prevent diarrhoea.
9, early feed
Sows began to increase their lactation levels from 5 days postpartum, reached the peak of lactation in 20 days, and gradually decreased after 30 days. At this time, the growth of piglets was gradually accelerating. Breastfeeding alone could not meet the nutrients needed for its growth. Feeding can promote the development of the digestive tract and digestive glands, avoiding pig litter, reducing diarrhea, and reducing death.
