Abstract
The invention relates to the technical field of beef cattle breeding, in particular to a preparation method of beef cattle feed. The preparation method comprises the following steps: s1, mixing 15-20 parts of zymophyte liquid, 40-60 parts of corn bran, 15-20 parts of rice bran and 3-6 parts of bone meal, performing anaerobic fermentation, drying and crushing to obtain bran leavening; s2, uniformly mixing 30-50 parts of silage straw powder, 15-30 parts of soybean meal, 10-30 parts of alfalfa powder, 12-25 parts of ryegrass powder and 0.1-2 parts of compound bacterial liquid, fermenting, and drying to obtain a straw fermented product; s3, mixing the bran ferment and the straw ferment, and adding 0.5-1 part of multivitamin, 1-2 parts of sodium chloride and 1-5 parts of conjugated linoleic acid to obtain the composite vitamin-rich straw. The invention can not only make full use of resources such as straws and bran, but also introduce microbial flora, improve the utilization rate of the feed and improve the utilization value and the culture benefit.
Description
Technical Field
The invention relates to the technical field of beef cattle breeding, in particular to a preparation method of beef cattle feed.
Background
With the rapid development of the breeding industry in China, the market of feed raw materials is in short supply, in particular to the food of protein feed. At present, the beef cattle breeding feed sold in the market does not take plant fiber suitable for the digestion characteristics of beef cattle as a main raw material, has extremely low fiber content and incomplete nutrition, and is not beneficial to the requirements of digestion and complete absorption of the beef cattle. And because the traditional feed processing does not involve biochemical changes basically, various bran and straw resources cannot be fully utilized. The microbial fermentation is a highly concentrated biochemical reaction process, the microbial fermentation technology can change waste into valuable, reduce the feed cost, improve the breeding benefit, promote the comprehensive development of the beef cattle breeding industry, has good economic and ecological benefits, and becomes a hotspot of the current feed industry research. However, the common bioprotein feed starter has the problems of relatively single bacteria, low activity, slow material fermentation start, incomplete degradation of harmful substances, more harmful mixed bacteria, incapability of ensuring the quality, safety, sanitation, feeding effect and the like of the bioprotein feed.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides the preparation method of the beef cattle feed, which not only can make full use of resources such as straws and bran and the like to change waste into valuable, but also can introduce microbial flora to promote the digestion and absorption of various nutrient components in the feed in the intestinal tracts of beef cattle, improve the utilization rate of the feed and improve the utilization value and the breeding benefit.
The technical scheme of the invention is realized as follows: a preparation method of beef cattle feed is characterized by comprising the following steps: the method comprises the following steps:
s1), taking 15-20 parts of zymophyte liquid, 40-60 parts of corn bran, 15-20 parts of rice bran and 3-6 parts of bone meal according to parts by weight, uniformly mixing, adjusting the pH to 5.5-6.5 by using alkali liquor, placing the mixture under the conditions that the temperature is 40-45 ℃ and the relative humidity is 80-90% for anaerobic fermentation for 24-72 hours, drying and crushing the mixture into particles with the particle size of 3mm to prepare a bran fermented product for later use;
s2), uniformly mixing 30-50 parts by weight of silage straw powder, 15-30 parts by weight of soybean meal, 10-30 parts by weight of alfalfa powder, 12-25 parts by weight of ryegrass powder and 0.1-2 parts by weight of composite bacterial liquid, adjusting the pH value to 5.5-6.5 by using alkali liquor, placing the mixture under the conditions that the temperature is 30-40 ℃ and the relative humidity is 75-85% for anaerobic fermentation for 24-60 hours, drying and crushing the mixture into particles with the particle size of 3mm to prepare straw fermentation products for later use;
s3), mixing the bran leavening obtained in the step S1 with the straw leavening obtained in the step S2, adding 0.5-1 part of multivitamin, 1-2 parts of sodium chloride and 1-5 parts of conjugated linoleic acid, and uniformly stirring to obtain the beef cattle feed.
The zymophyte liquid is prepared by mixing zymophyte and purified water, and the mass percentage concentration of the zymophyte liquid is 0.3-3%.
The zymophyte comprises one or more of aspergillus niger, bacillus subtilis, bacillus coagulans, lactobacillus plantarum and candida utilis.
Preferably, the number range of the living cells of each strain in the zymophyte bacteria is as follows: aspergillus niger of 102～1010CFU/g, Bacillus subtilis 102～108CFU/g, Bacillus coagulans is 104～106CFU/g, Lactobacillus plantarum 102～1010CFU/g and Candida utilis of 102～1012CFU/g。
The compound bacterium liquid is prepared by mixing compound bacteria and purified water, and the mass percentage concentration of the compound bacteria is 0.5-5%.
The compound bacteria comprise one or more of bacillus thuringiensis, actinomyces tundifoliae, streptococcus thermophilus, lactobacillus bulgaricus, saccharomyces cerevisiae and enterococcus faecalis.
Preferably, the straw powder is selected from one or more of corn straw powder, rice straw powder, wheat straw powder and reed straw powder, and the particle size of the straw powder, the alfalfa powder and the ryegrass powder is 60-100 meshes.
The invention also discloses an application of the beef cattle feed, which is characterized in that: the beef cattle feed is adopted to feed beef cattle of 3-4 months of age, and each beef cattle is fed with 30kg of solid feed every day for 2 times every day.
The invention solves the defects in the background technology and has the following beneficial effects:
the beef cattle feed prepared by the preparation method provided by the invention does not contain antibiotics and hormones, is green and safe, and has balanced nutrition; the invention can ferment and convert agricultural resources such as bran, straw and the like through microbial bacteria, and when the invention is used in beef cattle breeding industry, the ideal daily gain effect of beef cattle can be achieved, the healthy growth of beef cattle is ensured, the feeding cost is reduced, the feeding time is shortened, and remarkable economic benefit is obtained. The corn bran is fermented by the zymophyte, so that the content of crude protein and crude fiber contained in the corn bran can be improved to some extent after fermentation, and sugar and enzymes generated in the fermentation process of the mixed yeast are favorable for animal feeding, and the palatability and the digestibility of the feed can be improved. The invention also adopts the compound bacteria to ferment the straw, soybean meal, alfalfa powder and ryegrass composition, thereby improving the contents of polyphenol, alkaloid, flavone, crude protein, crude fiber, amino acid and mineral elements in the feed.
