The invention relates to a low-emission environmentally-friendly feed as well as a preparation method and application thereof. The feed comprises the following components in parts by weight: 70-80 parts of carriers, 3-8 parts of
plasma protein powder, 3-8 parts of dried porcine soluble, 2-5 parts of white
fish meal, 4-6 parts of whey
powder, 1-4 parts of wheat
bran and 3-5 parts of a premix. The preparation method of the feed is prepared through the following steps of weighing the carriers of which the
mass is 50-70% of the total
mass of the carriers, adding the
plasma protein powder, the dried porcine soluble and the wheat
bran in parts by weight, uniformly mixing the carriers, the
plasma protein powder, the dried porcine soluble and the wheat
bran, and performing crushing and
drying so as to obtain a mixture A; uniformly mixing the surplus carriers, the white
fish meal, the whey powder and the premix in parts by weight, and performing
quenching and
tempering so as to obtain a mixture B; and mixing the mixture A and the mixture B according to the
mass ratio of the mixture A to the mixture B being 1:1 so as to obtain the feed. Compared with the prior art, the feed disclosed by the invention is balanced in
nutrition, the absorption and
utilization rate of organisms to the feed can be effectively increased, the growth and the development of pigs can be promoted, the content of
nutrient substances in the excrement of the pigs can be obviously reduced, and the feed has good application prospects.
