Feed additive capable of replacing antibiotics in pig feed, and pig feed

Abstract

The invention discloses a feed additive capable of replacing antibiotics in a pig feed. The feed additive comprises 15-20 parts by weight of ampelopsis grossedentata extract, 20-30 parts by weight of Chinese gall and 40-50 parts by weight of yeast cell walls, wherein the ampelopsis grossedentata extract contains 35-45% of ampelopsis grossedentata flavone and 20-30% of dihydromyricetin, and the yeast cell walls contain 45-55% of immune polysaccharide. The invention also discloses the pig feed added with the feed additive and used for weaned piglets. The feed additive is used in the production of the feed for weaned piglets to replace antibiotics, and has the effects of inhibiting bacteria and promoting the growth of livestock.

Description

technical field [0001] The invention relates to a feed additive that can replace antibiotics in pig feed, and also relates to a pig feed containing the feed additive that can replace antibiotics in pig feed. Background technique [0002] In the prior art, antibiotics are usually added during the production of feed for weaned piglets. Antibiotics include aureomycin, quinocetone, and acetene sulfate. The effect of adding antibiotics is: aureomycin has an inhibitory effect on both gram-positive and negative bacteria. It can treat typhoid fever, pullorum and other diseases of livestock and poultry; quinocetone can promote growth and improve feed conversion rate, and can inhibit a variety of intestinal pathogenic bacteria, which can significantly reduce the incidence of diarrhea in livestock and poultry. The mechanism of action of quinocetone is mainly to promote the secondary increase of assimilation and growth hormone, and accelerate the growth of animals. And by effectively i...

Problems solved by technology

[0003] Over the years, the use of antibiotics in feed has improved the survival rate of poultry and livestock, but problems have emerged: for weaned piglets, their weak stomachs cannot withstand the dose of antibiotics; , these drug residues force the meat eaters to take the drugs left in the poultry body, which will affect the health of the eaters

[0004] Studies have shown that vine tea flavonoids have a good inhibitory and killing effect on intestinal pathogenic bacteria in vivo and in vitro, and can replace quinocetone in antibiotics in feed, and have a good application prospect in the prevention and treatment of intestinal pathogenic bacteria in pigs , but if it is used to completely replace antibiotics, there are still deficiencies, because in pig feed instead of antibiotics, it is still necessary to achieve the aureomycin that inhibits Gram-positive and negative bacteria in feed antibiotics, and the basic polypeptide antibiotics that can prevent and control the infection of sensitive bacteria. etc., the simple use of vine tea flavonoids, as a drug, has not been able to expand its added value in place of antibiotics, especially for the stomach of weaned piglets that can withstand the expansion of its added value in place of antibiotics, has not yet reached
