C: Disclosed is a healthy nutritious feed for animals, prepared by adding a microbial solution to feeding material at the volume-mass ratio of 1:2-3 (ml/g) and mixing same until uniform, wherein the feeding material is composed of the following raw materials in parts by mass: 50-99 parts of beans, 171-305 parts of corn, and 25-60 parts of auxiliary materials; and the auxiliary materials refer to one or a mixture of herbage, husks, wheat bran, soybean meal skin or sorghum husk. The nutritional ingredients of the healthy nutritious feed for animals are comprehensive and balanced. Domestic fowl and livestock raised with the healthy nutritious feed for animals have odourless animal faeces, bright fur and eyes, are active and strong, and have a good shape. The meat percentage of the fowl and livestock is 10% to 20% higher than that of common fowl and livestock.
D: An immunity-enhancing composition. The composition comprises the following components in parts by weight: sodium vitamin C 50-200 parts, vitamin A 0.1-1 part, zinc gluconate 10-30 parts, taurine 10-30 parts, a flower/fruit extract 10-20 parts, and spirulina powder 10-20 parts. The flower/fruit extract is prepared from the following ingredients in parts by weight: golden camellia 20-40 parts and fresh mulberries 30-60 parts.
