Additive composition used for piglet feed, compound premix and antibiotic-free piglet feed

Abstract

The invention provides an additive composition used for a piglet feed. The additive composition comprises tannic acid, sanguinarine and an epimedium herb extract, wherein the mass ratio of the tannic acid, the sanguinarine and the epimedium herb extract is (750-1300):50:(300-800). The invention also provides a compound premix containing the additive composition and an antibiotic-free piglet feed containing the additive composition. The additive composition, and the compound premix prepared from the additive composition, and the antibiotic-free piglet feed prepared from the additive composition have a plurality of functions of improving intestinal microflora balance of piglets, raising immunity, and resisting diarrhea. No antibiotic is added, so that the feed has high safety and accords with an ideal amino acid mode. Coordination on the aspects of electrolyte balance and mineral balance is carried out, so that the feed can comprehensively meet nutrient and health demands of piglets, and price performance ratio is taken into account at the same time so as to greatly raise benefits of pig farms.

Description

technical field [0001] The invention relates to the field of feed and feed additives, in particular to an additive composition for piglet feed, a compound premix and a functional antibiotic-free piglet feed containing the composition or the compound premix. Background technique [0002] In the livestock and poultry breeding industry, the unscientific use and abuse of antibiotics has attracted great attention from governments and industry insiders around the world. As early as 1968, Sweden began to ban antibiotics, and in 2006, the European Union completely banned the application of antibiotics. Therefore, antibiotic-free breeding is the general trend of the livestock and poultry breeding industry. [0003] Piglets are prone to physiological problems such as intestinal flora imbalance during feeding, and then diarrhea, nutritional deficiency, poor growth performance and other phenomena, which affect the production efficiency of pig farms. Under the trend of antibiotic-free br...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the physiological problems such as diarrhea that are prone to occur during piglet breeding and avoid the use of traditional feed containing antibiotics, one of the purposes of the present invention is to provide an additive composition for piglet feed, which can significantly reduce piglet feed. diarrhea problems and enables piglets to achieve good growth performance
