Low-emission environmentally-friendly feed as well as preparation method and application thereof

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of pig feed, and relates to a low-emission environment-friendly feed and a preparation method and application thereof. Background technique [0002] At present, with the rapid development of animal husbandry and intensive production, some breeders blindly pursue high-protein feed components and add a large amount of inorganic high-copper, high-zinc, high-iron and other trace elements to the feed. The amount of copper and zinc added It has reached or exceeded the minimum poisoning dose of pigs. Except for a small part absorbed by pigs, most of the trace elements are discharged into the environment with pig feces, which will lead to imbalance of nutrients in feed or low feed utilization rate, and then It causes indigestion in pigs, wastes a lot of protein feed, makes the content of nutrients in pig excrement high, causes a large amount of ammonia nitrogen deposition in the environment, and even causes serious ...

Problems solved by technology

In the technical scheme announced by the above-mentioned patent, the organic trace element additives used include amino acid copper, amino acid iron, amino acid manganese, amino acid zinc, which all belong to amino acid chelates. Although their chemical properties are stable and their biological potency is high, they can improve animal health. Production performance, but its effect is unstable, and the production process and detection method standards are not perfect, the process conditions are relatively harsh, and the cost is high; in addition, the non-starch polysaccharide enzyme used has poor stability in the gastrointestinal tract, and the compatibility of exogenous enzymes And the enzyme activity determination method is not uniform, the enzyme activity loss is relatively large under the high temperature, high pressure and high moisture conditions of the feed, and the phytase used loses in the high temperature, high pressure, high humidity or high moisture conditions in the process of crushing, premixing and granulation. Live the fastest, can not give full play to its effect
