Feed enzyme and its preparing process

Abstract

A feed enzyme is prepared through such steps as pulverizing straw or stalk, adding ammonium sulfate and calcium oxide, enclosing, preparing leavening from trichoderma, aspergillus and yeast through fermentation, adding the said leavening, Chinese-medicinal materials and nutrient additive to the said straw or stalk powder, and fermenting to obtain feed enzyme. Its advantages are simple preparing process, saving energy and low cost.

Description

technical field [0001] The invention belongs to a feed enzyme, and more specifically, the invention relates to a feed enzyme prepared by fermenting straw, and also relates to a preparation method of a feed enzyme. Background technique [0002] At present, straw processing in foreign countries is mainly used to feed ruminant cattle and sheep. The following methods are used: one is chemical treatment, the United States uses hydrogen peroxide to treat straw powder, and Western Europe, Canada, India and other countries use sodium hydroxide and sodium chloride to treat straw powder. Feeding cattle and sheep; the other is biological treatment, Japan uses white rotting fungus fermented straw powder to feed sheep; the third is hot-pressed hydrolysis, the Soviet Union bundles the straw, puts it in a pot and soaks it for 5-6 days, and then removes it. Water, maintained at 150-160°C and 16 atmospheres for 2-3 hours, taken out to feed the cows; the fourth is v...

Problems solved by technology

The straws mentioned above are not pretreated, and the fermentation effect is poor. With sealed fermentation, although the lactic acid bacteria increase, the palatability of the straws is better, but the essential cellulose is reduced and the protein is not significantly improved, so it is not suitable for long-term feeding of chickens, pigs, etc. livestock
