Xinjiang fast-growing yellow feather broiler feed, preparation and application

The invention discloses Xinjiang fast-growing yellow feather broiler feed, preparation and application. The Xinjiang fast-growing yellow feather broiler feed consists of 0-14-day-age chick initial feed, 15-21-day-age chick feed, 22-42-day-age medium-boiler feed and 43-day-age market slaughter large boiler feed. According to a situation that the Xinjiang fast-growing yellow feather broiler has different nutrient requirements in different growth stages, a feed nutrient ratio of each stage is accurately designed, cottonseed protein is adopted, so that the content of protein is improved, and an absorption rate of protein amino acid is higher than the absorption rate of cottonseed meal; by use of addition of exogenous amino acid lysine, methionine, threonine and tryptophan, a balance mode of four types of amino acid can more reasonably prepare an amino acid demanded quantity of each stage; and through a feeding experiment, the average weight of the Xinjiang fast-growing yellow feather broiler is 3.05kg, a feed con
