Abstract

The invention discloses an antibiotic and health care feed addictive and the method for preparing the same. The feed addictive is prepared with divalent nantokite, zinc solution and montmorillonite through absorption and ion exchange reaction, the copper content in montmorillonite is 0.5-5% by weight percent, and zinc is 1-10% by weight percent. The feed addictive can be used for poultry, aquatic creature, cow and sheep, and it possesses strong antibiotic action. It is hard for bacteria to generate drug tolerance. The product can effectively inhibit the propagation of enteric pathogenic bacteria, which is good for secretory of digestive enzyme and digestion of feed. The product can dramatically increase animal survival rate, reduce loose bowel movement and increase production capacity.

Description

technical field [0001] The invention relates to an antibacterial and health-care feed additive and a preparation method thereof. Background technique [0002] There are a variety of bacteria in the digestive tract of animals, some can consume nutrients, and some can produce toxins and bacterial enzymes, which can directly or indirectly destroy the shape and function of the intestinal mucosa, thereby reducing the feed efficiency and growth of livestock and poultry performance. If the number of intestinal pathogenic bacteria exceeds a certain value, indigestion and diarrhea may occur in mild cases, and enterogenous systemic infection may occur in severe cases, even life-threatening, which makes antibiotics and antibacterial drugs widely used in animal husbandry. The extensive use of antibiotics has played a role in promoting the growth of livestock and poultry, preventing and resisting diseases to a certain extent. However, the long-term use and abuse of antibiotics has caus...
