Animal feed additive

Abstract

Disclosed is a safe and convenient means for supporting the digestive activity in an animal and increasing the feed efficiency. Specifically, disclosed is a means for preventing / treating an infectiousdisease by inhibiting the proliferation of a pathogenic bacterium or a coccidium in the intestine of the animal and, consequently, increasing the body weight of the animal. At least oneAspergillus bacterium selected from Aspergillus sojae, Aspergillus tamarii, Aspergillus foetidus,Aspergillus niger and Aspergillus oryzae, a culture containing an acidic enzyme produced by the bacterium, and Bacillus subtilis are administered to an animal in specified amounts.

Description

Technical field [0001] The present invention relates to Aspergillus bacteria having the ability to produce acid enzymes and animal feed additives containing Bacillus bacteria. Background technique [0002] Although feeds such as livestock and pets (hereinafter referred to as animals) undergo processing such as crushing, they generally do not undergo heat treatment or the like, so there is a problem that the digestion and absorption rate becomes low and the feed efficiency is poor. In addition, inflammatory bowel diseases such as ulcerative colitis and Crohn's disease, which are recently known as human diseases, have also been reported in animals, and there is a problem of causing symptoms such as diarrhea. In addition, it is also known that such inflammatory bowel disease reduces the absorption of feed or hinders healthy fattening. As pathogenic bacteria that cause intestinal infections in animals, pathogenic coliforms, Salmonella bacteria, Clostridium bacteria, and Curvularia b...

AI Technical Summary

Problems solved by technology

The growth-promoting effect of animals obtained by this method is partially recognized, but no studies have been conducted on the inhibition of the proliferation of pathogenic bacteria in the intestines of animals, and the prevention and treatment of intestinal infections, and such effects have not been recognized.

In addition, mixing two or more microorganisms and administering them to animals has not actually been studied

[0007] In addition, it has been reported that Bacillus subtilis has antibacterial activity against pathogenic bacteria such as pathogenic Escherichia coli (Patent Documents 7 and 8), but there is no study on oral administration to animals.

In addition, it is known that Bacillus subtilis DB9011 has aflatoxin decomposing property and inhibits the growth of fungi, so it is studied that it is added to feed (Patent Document 9)

However, the combination of Bacillus subtilis and microorganisms from other systems and their ingestion by animals has not been studied so far
