The management of sows during lactation is very important. If the farmers are doing the management of the sows during the lactation period, the sows will have sufficient milk, and the piglets will be able to drink enough milk and the natural resistance will increase and grow stronger. If the feeding management of the sows during lactation is not done, the sow milk will be reduced. The direct consequence of the low milk is that the piglets are prone to illness and grow thin.

1. What are the purposes and requirements for feeding lactating sows?

Pigs are mammals and therefore the main source of nutrition for piglets within three weeks of birth is breast milk. Only when the piglets get enough and good breast milk during the lactation period can they survive and grow healthily, in order to get the ideal larger weaning weight. Therefore, the purpose of raising lactating sows is to enable lactating sows to improve lactation capacity and provide sufficient milk for piglets to ensure the survival and rapid growth of piglets. At the same time, during the lactation period, the sows should be guaranteed to have healthy health, good sensation and normal body condition so as to be able to breed in time after weaning, which lays a good foundation for the smooth entry of the next breeding cycle.

2. How should the feed of lactating sows be prepared?

The feed of lactating sows should contain higher energy and protein levels. Therefore, the diet structure of lactating sows should be based on energy feed and protein feed, and the proportion of the total diet is about 85% at the beginning of lactation. ~90%, 75% to 85% in the middle of breastfeeding, 80% after breastfeeding. Some tubers, silage and leguminous hay flour can be used in winter and early spring diets; some green fodder can be included in summer and autumn festive diets or grazing. However, the feeding amount of the green roughage should be appropriate, and the general feeding amount should be controlled so that the crude fiber content in the whole diet is not more than 10%. All kinds of minerals, trace elements and Vitamins must be replenished in the feed, and plant-based feed alone cannot meet the needs of lactating sows. Certain feeds have a good effect on promoting sow lactation. Carrots, pumpkins, sweet potatoes in succulent feed, Jerusalem artichoke, sorghum in green fodder, clover, Chinese milk vetch and fresh sweet potato vine, barley, millet, broad bean, pea in seed feed, fishmeal and meat and bone meal in animal feed And skim milk, etc., are excellent feeds that can promote sow lactation, but pig farmers need to choose as appropriate.

3. How should lactating sows be properly fed?

Lactating sows begin to breastfeed at the beginning of pregnancy because of physical exertion and weakening after childbirth, and the digestive function has not fully returned to normal. Therefore, it is suitable to feed those easily digestible feeds such as cereal powder, wheat drum, etc., and then transition to normal after 5-6 days. The amount of feed and the amount of feed should be gradually increased to prevent the sow from overfeeding and affecting the appetite of the sow and causing indigestion. Feeding lactating sows should be mixed with water to make it moist or thick porridge, which is good for feeding and sow feeding. After entering the normal lactation period, you should pay attention to feeding the feet to avoid lactation due to insufficient nutrition. In addition to this, we must also pay attention to prevent overeating, so as not to affect the appetite and intake. The feed for suckling sows must be fresh and clean. The spoiled feed must not be fed to the lactating sow. Otherwise, in addition to affecting the health and lactation of the sow, it will also damage the health of the piglets and cause gastrointestinal diseases in the piglets. The grazing sows can be grazing and rearing in conditional areas. Grazing grazing not only enhances the sow's constitution and enhances lactation, but also facilitates the growth and development of suckling piglets.

Lactating sows control the amount of juicy and concentrate feeds in the days before weaning to encourage sows to reduce and stop the secretion of milk to prevent mastitis in sows. Pig milk contains up to 80% more water plus the water needed for sow metabolic activities, so lactating sows need a lot of water. It is determined that lactating sows need approximately 12 to 14 kilograms of water per head per day and must be fed in sufficient quantities per day. If the lactating sow lacks drinking water, even if the feed is very nutritious, the sow's milk production will be significantly reduced.

Sows need a lot of nutrients and water during lactation to secrete enough and high-quality milk to make the piglets in the lactating period healthier and stronger so that they can be fattened in the future.
