Feed formula capable of relieving zearalenone poisoning of fattening pigs

Abstract

The invention provides a feed formula capable of relieving zearalenone poisoning of fattening pigs. Shown by research results of the feed formula, when the feed formula capable of relieving zearalenone poisoning of fattening pigs contains 0.3mg/Kg of zearalenone (ZEN), vulva redness and swelling appear in sow pigs in 15d. After the feed formula capable of relieving zearalenone poisoning of fattening pigs, which contains a composition of probiotics capable of degrading the ZEN and mycotoxin degrading enzymes, is fed, the phenomena of vulva redness and swelling and womb swelling in the pigs canbe relieved. The composition of the probiotics capable of degrading the ZEN and the mycotoxin degrading enzymes is capable of obviously improving the degradation rate of the ZEN in empty intestines, can enable the growth performance of the pigs to approach the level of a control group, and is of far reaching importance on maintenance of the stability of intestinal microfloras of pigs and improvement of diastatic activity in the intestines.

Description

technical field [0001] The invention relates to the technical field of microorganisms, in particular to a feed formula capable of alleviating zearalenone poisoning of fattening pigs. Background technique [0002] Zearalenone (Zearalenone, abbreviated as ZEN), also known as F-2 toxin, is produced by Fusarium graminearum, Fusarium tricinctum, Fusarium culmorum, Fusarium equisetum ( A class of non-steroidal estrogen-like compounds produced by Fusarium equiseti), Fusarium sernitectum, and Fusarium solani under suitable conditions. [0003] The chemical name of ZEN is 6-(10 hydroxy-6 oxy-undecenyl) β-rapenolide, and the molecular formula is C 18 h 22 o 5 . Its six most common derivatives are zearalenol, 6c, 8c-dihydroxyzearalenediol, 8c-hydroxyzearalenone, 5c-formyl zearalenone, 7c- Dehydrozearalenone and 3c-hydroxyzearalenone. [0004] The presence of ZEN can be detected in most of sorghum, corn, wheat, rice, barley and other food crops and their agricultural by-products, ...

AI Technical Summary

Problems solved by technology

Among them, the physical method is mainly to add some minerals to absorb ZEN, but it does not completely eliminate ZEN, and also absorbs nutrients, resulting in nutrient deficiency

The chemical method relies on chemical reagents to destroy the structure of ZEN, but it is easy to pollute the feed and cause partial loss of nutrients and pollute the environment
