Problems solved by technology

Feeds are prone to mildew in high temperature and humid seasons. Mildewed feed not only reduces the nutritional value and affects palatability, but also the toxins produced by bacteria or molds such as aflatoxin will poison pigs and remain in pork and affect human health.
Lipids and other nutrients in the feed are continuously oxidized during the storage process, resulting in a decrease in the photosensitivity of the feed, a decrease in nutritional value, a shortened storage period and a decrease in palatability. Severe oxidation can lead to rancidity of the feed, protein destruction and pigment oxidation. , but also has a certain degree of toxicity, causing a certain degree of harm to pigs and bringing greater losses to farmers
[0003]At present, most of the anti-mold antioxidants on the market are simple compounds of anti-mold agents and antioxidants, which can only play the role of anti-mold and anti-oxidation. Anti-mold and antioxidants mainly composed of ingredients are also prone to toxic residues. For example, benzoic acid has superimposed poisoning, and some countries and regions have banned its use; Production time

Abstract

The invention provides a mould-proof antioxidant capable of increasing pig feed quality. A natural product, namely, soluble chitin, extracted from shrimp and crab shells is taken as a main component of a mould-proof agent and is combined with a composite antioxidant to exert functions, and the mould-proof antioxidant has the characteristics of long mould-proof period, good anti-oxidation effect, no toxic residue, safety and reliability, and can be used for replenishing nutritional ingredients required by the growth of live pigs and increasing the pig feed quality. After eating the feed in which the mould-proof antioxidant is added, the live pigs are increased in feed intake and obviously accelerated in body weight increase, and the slaughtering time is shortened.

Description

technical field [0001] The invention relates to an anti-mildew antioxidant for pig feed, in particular to an anti-mildew antioxidant which can improve the quality of pig feed. Background technique [0002] Feed mildew is a common problem all over the world, and it is caused by a large number of molds in feed. Feeds are prone to mildew in high temperature and humid seasons. Mildewed feed not only reduces nutritional value and affects palatability, but also toxins such as aflatoxin produced by bacteria or molds can poison pigs and remain in pork and affect human health. Lipids and other nutrients in the feed are continuously oxidized during the storage process, resulting in a decrease in the photosensitivity of the feed, a decrease in nutritional value, a shortened storage period and a decrease in palatability. Severe oxidation can lead to rancidity of the feed, protein destruction and pigment oxidation. , but also has a certain degree of toxicity, causing a certain degree of...
