Embodiment 1

[0028] A novel green and environment-friendly feed, wherein the feed is composed of a compound enzyme preparation for feed production by solid-state fermentation of Aspergillus niger and forage grass or crop straw (alfalfa or oats), and the feed compound enzyme preparation for feed production by solid-state fermentation of Aspergillus niger: Grass or crop straw = ratio of 0.05 to 2:1000. Among them, the compound enzyme preparation for solid-state fermentation of Aspergillus niger for feed production is produced by solid-state fermentation of Aspergillus niger strain QM-1. The preservation number of the Aspergillus niger strain QM-1 is CGMCC No. 19629, and the preservation date is May 7, 2020. It is preserved in the General Microorganism Center of China Committee for Culture Collection of Microorganisms (abbreviated as CGMCC, whose address is No. 3, Yard No. 1, Beichen West Road, Chaoyang District, Beijing). The compound enzyme preparation for feed contains 6 compound enzymes for...

Abstract

The invention relates to the technical field of animal feed nutrition research, in particular to novel green and environment-friendly feed and a preparation process thereof. The ratio of the feed compound enzyme preparation produced through aspergillus niger solid-state fermentation to forage grass or crop straw is (0.05-2): 1000, and the feed in the shape of grass meal, grass blocks or grass particles is prepared by a conventional feed crushing system, a mixing system and a granulating system for different livestock in different breeding periods. The novel feed can save resources, improve theabsorption and utilization of the feed by animals, increase the yield and reduce the pollution of livestock excrement to the environment, and is a green and pollution-free feed. A compound enzyme inthe feed can reduce the discharge amount of phosphorus in excrement so as to protect the environment; the feed intake and daily gain of animals are increased, and the production performance of animalsis improved; digestion and absorption by gastrointestinal tracts of animals are facilitated, and the effects of preventing diseases and promoting growth are achieved; absorption and utilization of nutrient substances are promoted; and the digestion and utilization rate of the feed is increased.

Description

technical field [0001] The invention relates to the technical field of animal feed nutrition research, in particular to a novel green and environment-friendly feed and a production process thereof. Background technique [0002] New green feed is a research hotspot in recent years. The scientific use of new feed can not only improve the utilization rate of livestock feed, increase milk production rate and meat production rate, but also will not remain in livestock products, which will endanger human health. It belongs to green Pollution-free products, some new feeds can also enhance the immunity of livestock and improve the anti-stress ability of animals. In addition, the new green feed can also reduce the discharge of nitrogen and phosphorus in animal excrement and protect the ecological environment. [0003] Compound enzymes for feed are synthesized in vivo and further collected, extracted and purified artificially. They are a kind of biologically active polymer substances...
