Feeding and Managing Piglets Live Longer

<

(1) Increase the birth weight of piglets. The higher the mortality of piglets, the lower the mortality rate and the faster the weight gain in the future. Therefore, the daily feeding amount should be increased from 2.8 to 3 kg for the 90th day of pregnancy to the 3rd day before delivery. The digestive energy content of the sow diet is 12.9 MJ/kg, and the crude protein content is 14% to 15%. In snow, it is best to add 2% to 3% of oil in the diet provided to promote the development of the sow's mammary gland, increase its postpartum milk yield and milk fat content, and increase the birth weight and energy of the piglets. Reserves are conducive to the survival and development of piglets. (2) Increase the milk production of sows. Breast milk is the only source of nutrition and immune antibodies for piglets before the age of 3 weeks. In order to increase the milk yield of sows and ensure the development of piglets, sow the weight loss of sows during the lactation period and the early estrus after weaning, we must avoid the sows’ gestation period of excessive fat, and secondly adopt high nutrient levels during sow lactation (especially For high-energy diets, open-fed diets are best done by adding 5% fat to their diet during the hot season. In order to increase the feed intake of sows, the number of feedings should be appropriately increased, and they can be fed three times a day and fed once a day. Alternatively, wet mixes can be used to allow sows to eat freely while ensuring sufficient drinking water. (3) Train piglets to eat early. The extent to which breast milk meets the nutritional needs of piglets is 97% at 3 weeks of age, 37% at 4 weeks, and only 28% at 8 weeks of age. Only the successful training of piglets to eat early can stimulate the improvement of the gastrointestinal tract development and secretion of piglets and alleviate the contradiction between nutrient supply and demand after 3 weeks of age. It has been proved that the intake of 500 g of feedstuff before weaning can reduce nutrient malabsorption and diarrhea caused by dietary sensitization after weaning. It is difficult to train piglets before 3 weeks of age to feed, but they must be patient. The first is to train early and train their drinking water from 3 to 5 days of age, and train their feed from 5 to 7 days of age. The second is to use high-energy, protein-rich, digestible, and good-tasting starting materials. Many pig farmers are only considered as small accounts, not as general ledgers. The provision of self-made piglets or purchase of low-end piglets is intended to reduce the cost of feed, but the results are counterproductive. The losses caused by the low rate of piglet breeding and the small weight are very high. The amount of feed consumed per kilogram of weight gain for piglets before 6 weeks of age is very small. The use of high-priced high-quality piglets results in a significant increase in the survival rate and daily gain of piglets, resulting in greater benefits.
