Special beer yeast composite lick brick for cows, and preparation method thereof

Abstract

The invention discloses a special beer yeast composite lick brick for cows, and belongs to the field of feed additives, wherein the special beer yeast composite lick brick is prepared from the following raw materials by weight: 90-92.5% of beer yeast powder, 6-8% of milkvetch root polysaccharide, and 1.5-2% of water. The preparation method comprises: (1) raw material pretreatment: respectively crushing beer yeast powder and milkvetch root polysaccharide until all the crushed particles can completely penetrate through 1.25 mm sieve holes; (2) mixing: placing the crushed beer yeast powder and the crushed milkvetch root polysaccharide into a mixer, spraying water into the mixer in a spraying manner to mix the water, the beer yeast powder and the milkvetch root polysaccharide, and mixing for 15 min after adding the water; and (3) brick preparation: taking 5 kg of the mixed material obtained in the step (2), pouring into a 5000 KN pressure four-column hydropress, and carrying out pressing molding. According to the present invention, the special beer yeast composite lick brick has characteristics of natural property, environmental protection, health and safe and convenient use, and has beneficial effects of feed conversion utilization rate improving, cow immunity improving, disease resistance improving, and the like.

Description

technical field [0001] The invention belongs to the field of feed additives, and in particular relates to a beer yeast compound lick brick specially for cattle and a preparation method thereof. Background technique [0002] In recent years, due to the improvement of people's understanding of the toxic and side effects of chemically synthesized drugs, the domestic and foreign medical circles have begun to pay attention to the development of natural herbal medicines. The demand for developing Chinese herbal medicine additives with less toxic and side effects, significant curative effect, and both medicinal and nutritional properties is becoming more and more urgent. For livestock and poultry drug resistance and drug residues and the problem of improving feed utilization, nutritionists at home and abroad have done a lot of research work and proposed many solutions and methods. To solve the problem of drug residues, add probiotics, enzyme preparations, etc. to improve feed util...

Problems solved by technology

For example, the application of brewer's yeast or brewer's yeast powder in high-end aquaculture and some pellet feeds and concentrated feeds has achieved certain effects, but the application in cattle breeding has not been reported. The reason is mainly related to cattle. It is related to feeding habits and feeding methods. Cattle are herbivores, and powdery and small pellet feeds are not conducive to long-term feeding, which restricts the application of brewer's yeast powder in cattle breeding.

In the prior art, there is no report on the application of brewer's yeast powder and astragalus polysaccharide together in livestock and poultry feed
