Purpose and use method of supported nanometer zinc oxide being adopted as intestinal health regulator of chickens

The invention discloses a purpose and a use method of supported nanometer zinc oxide being adopted as intestinal health regulator of chickens. The purpose of the supported nanometer zinc oxide being adopted as the intestinal health regulator of the chickens is a composite material which adopts the kaolin or the montmorillonite or the attapulgite or the sepiolite as carrier to carry the supported nanometer zinc oxide. In the composite material of the supported nanometer zinc oxide, the weight percent of the zinc oxide is 10-50%. The use method of the supported nanometer zinc oxide being adopted as the intestinal health regulator of the chickens comprises a step of adding the zinc to the chicken feed according to the dose of 40-100 mg / kg. When the supported nanometer zinc oxide is used for feeding the chickens, the zinc oxide is slowly released in the intestinal tracts of animals, and more zinc oxide can reach to the intestinal tracts in molecular morphology to realize the control effect of the intestinal health. The supported nanometer zinc oxide which is added to the diet is obviously reduced, the daily gain of the chickens is increased, the intestinal morphology is improved, and the intestinal mucosal barrier is protected. Because the integrity of the intestinal tracts is improved, the damage of the chickens caused by clostridium is reduced.
