Below I will specifically talk about how to match the appropriate diet for piglets. First, meet the energy and protein required for the growth and development of piglets. Because the muscles of piglets grow and develop very fast, and protein's metabolism is also very vigorous, it is necessary to scientifically supplement high-quality energy and protein raw materials according to pig breeds and practical experience. Second, add all kinds of vitamins needed by piglets to the feed. Piglets need vitamins to participate in metabolic reactions, such as vitamin A, vitamin D, vitamin C, vitamin E and vitamin B2. Vitamin C can directly kill bacteria and viruses in pigs, so the demand for vitamin C is extremely important. Third, supplement the required mineral elements. Because the bones of piglets develop rapidly, it is necessary to provide enough mineral elements such as calcium and phosphorus for piglets to ensure the normal development requirements of piglets, and zinc and selenium should also be supplemented. Fourth, add a certain amount of probiotics. Probiotics is a kind of natural bioactive preparation, which can partially replace vitamins, and has the advantages of health care, promoting the growth and development of piglets, and improving the utilization rate of feed. It is very necessary to add proper amount of probiotics to the diet to improve the immunity of piglets.
