How to do good feed nutrition management in early nursing pigs?

The main tasks of the nursery are to allow the weaned piglets to smoothly transition from weaning period, to develop good behavioral norms (fixed feeding, fixed sleeping and fixed excretion), and to maintain a satisfactory growth rate. For a smooth transition to weaning, nutrition and feeding are particularly critical.
Due to weaning, the sow's shelter and rations have been lost, coupled with behavioral disturbances such as penning and herding, so weaned piglets are in a state of turbulent stress. When weaning at 4 weeks of age, the digestive system is not fully developed, and it takes a period of adjustment and adaptation after weaning. The stress of the weaning period hinders the development of the digestive and absorption systems, so good nutritional care is essential.
Breastfeeding and intestinal development
The purpose of early supplementary feeding for suckling piglets is to adapt to the feed environment as soon as possible after weaning, to be familiar with the shape and taste of the feed, and to increase the feed intake after weaning. Piglets begin to produce a small amount of hydrochloric acid and digestive enzymes in their stomachs at about 14 days of age. Therefore, about 2 weeks after birth, piglets can use a disc-type feed trough to add a small amount of opening material to let them slowly start playing Learn to eat. Once the mouth-feed is eaten, the acid and enzymes produced in the stomach increase rapidly, which will accelerate the decomposition and absorption of the feed, and there is acid in the stomach, and harmful bacteria such as E. coli will not multiply.
After the piglets quickly adapt to weaning and feed intake, the food in the stomach will stimulate the secretion of new digestive juices. Weaned pigs will normally digest food, absorb nutrients, and adapt to the environment of the nursery. If the piglets are not adapted to the nursery environment after weaning, and only consume very little feed, the secretion of digestive juices such as gastric acid will decrease sharply, and the acidity in the stomach will decrease. Growth eventually leads to piglets being malnourished, wasted and even killed.
Pigs are only animals living in groups. They are accustomed to sow feeding with concentrated milk. They like scramble and often imitate the behavior of pigs in the same pen, including feeding, sleeping and excretion. Therefore, when the pigs arrive at the nursery, they must create conditions so that they can eat at the same time. When they hear or see other pigs arch out of the feed, they will be tempted to increase the feed intake.
Feeding times and feed patterns
After birth, the sow will call the piglets to suckle about every 1 hour, and once weaned, the piglets will leave the sow, live independently, find their own feed and water, so they must be adjusted as soon as possible. In the initial period, you should simulate the habit of breastfeeding, feeding once every 1 hour (the interval time will be gradually increased later), and hit the trough to form conditioned reflexes and develop good behavior habits. In terms of feed form, the transition from liquid milk to solid feed requires a transition. Therefore, in the piglet training phase, a small amount of water can be added to the feed, and the wet mix is gradually transitioned to powder and pellets.
Because the piglets are just weaned, the feeding should follow the principle of small and multiple feedings. While ensuring that the pigs can feed at any time, waste must be avoided. If a large amount of feed is fed into the trough at one time, the saliva flowing out of the mouth of the piglets during feeding will cause the feed to cake and mold, which will affect the freshness of the feed and cause piglet intestinal diseases. In addition, after the piglets chew, there will be a lot of powder left. Covering the feed with powder can cause piglets to refuse to feed. Therefore, the feed should be sufficient and not wasted.
Pigs are only raised in groups and like scramble. When designing the trough, we must minimize feed waste and take care that the pigs can eat at the same time to increase the feed intake. Round feed troughs do this better than other types of troughs. Check the feed in the trough every day, and clean up the agglomerated feed and feed contaminated with feces and urine to increase the feed freshness
