Mixed feed additive capable of improving immunity of nursery pigs and preparation method thereof

Abstract

The invention belongs to the technical field of pig feed and particularly relates to a mixed feed additive capable of improving immunity of nursery pigs. The mixed feed additive comprises, by weight percentage, 10-20% of taurine, 5-10% of chitosan, 20-40% of nucleotide, 5-10% of saccharicterpenin and 20-60% of glucose, and the finished additive is obtained after the raw materials are evenly mixed. The weight percentage of the finished additive in complete feed is 5%.. The mixed feed additive is favorable for improving immunity of the nursery pigs, reduce death rate and improve culture benefit.

Description

technical field

[0001] The invention belongs to the technical field of pig feed, and in particular relates to a mixed feed additive for improving the immunity of nursery pigs and a preparation method thereof. Background technique

[0002] In the modern pig production process, "nursery pigs are difficult to raise" is a problem encountered by the majority of farmers, and it is also a key factor restricting the rapid development of the industry. Nursery pigs refer to weaned piglets. At this stage, they have the characteristics of fast growth and development, high susceptibility to diseases, and need to be carefully fed. In actual production, the nursery pig stage has high morbidity, high mortality, and low survival rate, resulting in reduced pig raising benefits. The main reasons for "nursery pigs are difficult to raise" are as follows: one is the change of nutrition, from mainly eating liquid breast milk to eating solid feed; Completely independent life; the third is the cha...

Examples
