Chicken feed based on plant and metal ion chelating solution and application of feed

The invention relates to the technical field of microbial diversity feed processing, in particular to chicken feed based on a plant and metal ion chelating solution and application of the chicken feed. According to the invention, the selenium and/or iron chelating solutions of leucaena leucocephala with small leaves, alfalfa, mulberry leaves and pennisetum purpureum are mainly researched; the research finds that the oxidation resistance of the alfalfa and selenium chelating solution is much higher than that of other forage grass, and the DPPH scavenging capacity reaches 93% and is equivalent to that of vitamin C; through feeding experiments, it is found that when the plant chelating solution is added into basic feed, the dripping loss rate of chicken can be obviously reduced, and the chicken quality can be improved; through formula research, it is found that when 4% by mass of an alfalfa and selenium chelate and 2% by mass of a pennisetum purpureum and iron chelate are preferably selected in a feed formula to
