Selective breeding method by comprehensive selection indexes of resistance of Eimeria tenella of chickens

The present invention relates to the field of poultry breeding for disease resistance, particularly to a method for establishing selective breeding chicken Eimeria resistance resistance chicken comprehensive selection index screening individuals. The method of plasma on the 8th day after Chicken chicks in a particular age bird gavage a number of Eimeria tenella sporulated oocysts, weight gain was measured 3-5 days after infection, and the infection peroxide catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), malondialdehyde (MDA) concentration and interferon gamma] (IFN-γ), the above-described 6 indicator data into standardized Z value is substituted into the formula to build an integrated comprehensive selection index to select an index value of each individual, the individual elected to stay chicken resistance value depending on the size.
