When the piglet is very small, its digestive system is not yet fully developed, and it can be difficult to digest solid food. In fact, in the first 2 weeks of life, piglets can only fully digest milk protein (casein), lactose, glucose and fat. The suckling pigs at this stage are mainly dairy products. By 2-3 weeks of age, the piglet's enzyme system has evolved to digest more starch, sucrose and non-milk proteins. Piglets supplemented with suckling pigs will develop more mature than piglets that only breastfeed. By supplementing the suckling pig feed, the development of the digestive system of the piglet can be promoted to meet the needs of weaning. In addition to reducing weaning stress, supplementing piglets also has the following benefits: 1. It can minimize the impact of different milk supply of different nipples. 2. The piglets can be stably and continuously gained weight before weaning. 3, the efficiency of early weight gain is the highest, supplement feeding piglets can make piglets reach the maximum weaning weight, thereby reducing the age of the bar. 4. Efficient use of suckling pigs makes early weaning possible, thereby reducing the amount of feed used in sows during lactation and reducing the cost of sows. process Piglets of different litters have different times of feeding piglets, but usually start at 1-2 weeks of age. As early as 2-3 days old, you can sprinkle a few feeds or grains in the piglet area to induce piglets to feed. Sprinkling these foods on clean soil can sometimes stimulate piglets to eat. Until 2-3 weeks of age, piglets will obviously consume a certain amount of suckling pigs. Note that the amount added each time must be small, and the leftovers should be removed every day. The feed can be placed on a clean floor, but it is best to place it in a rotating depression or in a ceramic dish. Add five or six times a day, and as the feed intake increases, the feed can be placed in a solid tank. However, the amount added should allow the piglets to finish eating within 24 hours. As the piglets grow, their feed intake will increase, which can be changed to a small automatic trough. However, the amount of feed contained in the trough should not exceed the feed intake for several days, and it is still required to check daily to see if the trough is clogged and the material is degraded. The packing should be based on the principle of a small number of times. Make sure the feed is fresh and palatable to stimulate the interest of piglets. In addition to suckling pigs, it is also important to provide clean, fresh drinking water to piglets throughout the day. Piglet feed is mainly used to supplement the nutritional needs of piglets. The nutritional needs of piglets with high-yielding sows often exceed the sow's lactation capacity, which in turn requires piglets. In the practice of pig farms, commercial piglets are often purchased, which are processed from cooked grains and a large number of dairy products. The foodstuff should contain at least 15.0 MJ/kg (DE/kg) of digestion energy and 0.9 g of digestible lysine/MJDE. As mentioned above, this feed is largely based on dairy products, while the next suckling/weaning material also contains at least 5% milk powder. For 14 days of weaning, the requirements are more stringent. Supplemental feeding of piglets can be achieved by increasing the weight gain of piglets, reducing the problem of weaning, and making the weight of the pigs more uniform. The benefits of these effects are sufficient to make up for the cost increase brought by the piglets. If weaning is 24-28 days old, then the piglet should be fed 600g/head before feeding. If the feed intake before weaning is low, and the feed management after weaning cannot keep up, piglets will easily develop an antigenic response to the feed after weaning. It is best to supplement more than 250g of suckling pig material before weaning at three weeks of age, and 400g for weaning at 4 weeks of age. After weaning, the feed intake target during the first week is 150 g/day, and the second week should be increased to 250-300 g/day.
