Additive for animal feed

Abstract

To promote the digestion of an animal to thereby elevate the feed efficiency or prevent or ameliorate intestinal infections such as inflammatory intestinal injury of the animal, a combination of at least one fungus selected from Aspergillus sojae, Aspergillus tamarii, Aspergillus foetidus, Aspergillus niger, and Aspergillus oryzae with an acidic enzyme produced by the fungus is administered to the animal.

Description

technical field The present invention relates to feed additives for animals containing Aspergillus bacteria capable of producing acid enzymes. Background technique Feeds for domestic animals and pets (hereinafter referred to as animals) are processed such as pulverization, but usually do not undergo heat treatment, etc., so there are problems of low digestibility and poor feed efficiency. In addition, recently, inflammatory bowel disorders such as ulcerative colitis and Crohn's disease, which are known as human diseases, have also been reported in animals, causing symptoms such as dysentery. The above-mentioned inflammatory bowel disease is known to reduce feed absorption or prevent healthy and healthy fattening. Pathogenic Escherichia coli, bacteria belonging to the genus Salmonella, bacteria belonging to the genus Clostridium, bacteria belonging to the genus Campylobacter, etc. are known as pathogenic bacteria causing intestinal infection in animals. The abnormal reprodu...

Problems solved by technology

However, the occurrence of hepatocellular tumors was observed in mice administered with kojic acid, and the possibility of liver carcinogenesis of kojic acid was also shown in rats

In addition, it is not clear whether there is genotoxicity, and the possibility of genotoxicity cannot be denied
