NOVELTY - A young animal non-livestock biological feed includes dietary probiotics and/or bio-fermentation feedstock, such as fermented soybean meal and/or fermented corn; dietary enzyme; innovative feed ingredients comprising broken yeast or broken beer yeast and broken rice or rice; mineral raw materials comprising calcium hydrogen phosphate, calcium carbonate, rice chaff and sulfate minerals; intestinal microbial nutrition having affinity for intestinal microbial carbohydrate and/or peptide; and animal immunity enhancing raw materials comprising nucleotide and/or oligosaccharide.    USE - Young animal non-livestock biological feed.    ADVANTAGE - The feed is not harmful to people, does not affect growth and production of livestock and poultry but increases survival rate by 3-5%, reduces feed consumption/weight ratio to 0.3-0.4, and has economic efficiency of up to 10-15%, controllable safe range of arsenic, lead, chromium, cadmium and copper heavy metal, and no antibiotics, drug residues and hydrogen peroxide substance which ensures safety of meat and improves meat flavor.    DETAILED DESCRIPTION - A young animal non-livestock biological feed comprises dietary probiotics and/or bio-fermentation feedstock, such as fermented soybean meal and/or fermented corn; dietary enzyme; innovative feed ingredients comprising broken yeast or broken beer yeast and broken rice or rice; mineral raw materials comprising calcium hydrogen phosphate, calcium carbonate, rice chaff and sulfate minerals; intestinal microbial nutrition having affinity for intestinal microbial carbohydrate and/or peptide; animal immunity enhancing raw materials comprising nucleotide and/or oligosaccharide; energy raw materials aging; and antibiotics and pharmaceutical additive-free feed. INDEPENDENT CLAIMS are included for:    (1) preparation of biological feed comprising adding dietary probiotics and/or bio-fermentation feedstock with intestinal microbial nutrition, controlling water sanitation, and adding antibiotics and pharmaceutical additive-free feed;    (2) preparation of non-hormonal, chemical, sweetener, flavoring agent and preservative livestock and poultry feed comprising preparing hormone, chemical sweetener, flavoring agent and preservative-banned livestock and poultry feed, adding enzyme comprising amylase and protease, reducing heavy metal content, such as iron, copper, zinc and manganese, and adding organic feedstock comprising propionic acid and formic acid;    (3) preparation of low heavy metal-containing animal feed comprising preparing arsenic and chromium-banned poultry feed formulation, reducing iron, copper, zinc and manganese, and adding non-primary mineral raw materials, such as heavy calcium carbonate, medical stone powder and fluorine; and    (4) waste treatment method comprising adding feed production wastewater with straw or lignite, mixing with fermentation bacteria, fermenting for 15-20 days, turning for 3-4 times, and drying.
