Description

45% small conservation concentrated material and preparation method thereof

Technical Field

The invention belongs to the technical field of feeds, and particularly relates to a 45% small nursery piglet concentrated feed capable of protecting piglet intestinal tracts and improving piglet autoimmunity and a preparation method thereof.

Background

In order to control diarrhea of piglets and improve the growth speed of piglets, breeders add a large amount of high-dose antibiotics, high copper, high zinc and high-dose arsenic preparations into feed for a long time. The additives are not known to play the roles of brightening a temporary skin, promoting growth and controlling diseases. After long-term use, the negative effects of white hair and skin, slow growth, low disease resistance and the like of the piglets appear in the later breeding period or the piglet stage. Because such substances can cause serious damage to immune organs such as intestinal tracts, livers and spleens, the substances are also one of important factors for ineffective immunity and ineffective treatment in modern breeding.

Therefore, the promotion of the development of the pig autoimmune system and the improvement of the pig disease resistance are important means for essentially solving the problems of high morbidity and slow growth of the contemporary pig herd. The intestinal tract is the main organ for digestion, absorption and utilization of pig nutrients and is also the largest immune organ. The healthy development of the intestinal tract of the piglets determines the health condition of the pigs and the occurrence of epidemic diseases to a great extent, is a big subject of animal nutrition research, and is a practical problem to be solved urgently in the breeding industry. However, most nutrition workers basically concentrate the protection of the intestinal tract in creep feed at present, and the attention degree of the intestinal tract protection in the nursing stage is far from insufficient. The essence is that the intestinal growth and immune system of the piglets are not healthy enough in the nursery stage, and the resistance to diseases is not strong enough.

Therefore, the design of the small green conservation feed capable of protecting the intestinal tracts of the piglets and improving the immunity of the piglets is particularly important for the pig industry, not only can reduce the morbidity of the piglets in the piglet stage and promote the growth of the piglets, but also can lay a strong physique foundation for later fattening, shorten the fattening time and increase the economic benefit.
