preparation example Construction

[0028] A preparation method for beef cattle feed, comprising the steps of:

[0029](1) According to the number of parts by mass, take 290-300 parts of wheat grains, 5-10 parts of Polygonum, 155-200 parts of cassava dregs, 0.5-0.8 parts of calcium carbonate, and 100-120 parts of nutrient salt solution, and adjust the pH to 5.0~5.2, stir evenly, sterilize at 121°C for 20 minutes to obtain a sterilized mixture, take the culture solution of Aspergillus niger, Saccharomyces cerevisiae and Bacillus licheniformis and mix it according to the mass ratio of 5:5:1 to obtain a mixed bacterial solution, and inoculate at 13% Inoculate an appropriate amount into the sterilized mixture, ferment and cultivate at 28-35°C for 4-6 days, take the fermented product and dry it, crush it through a 100-mesh sieve, collect the sieved particles, and set aside;

[0030] (2) Take the pretreated Trichosanthes seeds and mix them with n-hexane at a mass ratio of 1:9, ultrasonicate at 58~60°C and 150~180W for...

Embodiment 1

[0034] Aspergillus niger, Saccharomyces cerevisiae, Bacillus licheniformis: Stored on slopes at -80°C in the laboratory.

[0035] Aspergillus niger culture medium: inoculate Aspergillus niger into PDA liquid medium, culture at 25°C for 5 days, pick the culture medium and add 0.1% Tween-80 at a mass ratio of 1:10 to elute spores to obtain Aspergillus niger culture medium; Yeast culture medium: inoculate Saccharomyces cerevisiae into YPD liquid medium, culture at 25°C, 180rpm for 12 hours to obtain Saccharomyces cerevisiae culture medium; Bacillus licheniformis culture medium: inoculate Bacillus licheniformis into liquid LB medium, 30°C, 180rpm Shake culture for 12 hours to obtain Bacillus licheniformis culture solution.

[0036] Nutrient salt solution: in parts by mass, 50 parts of glucose, 75 parts of urea, 25 parts of potassium dihydrogen phosphate, and 100 parts of water are mixed.

[0037] Pretreatment of Trichosanthes seeds: Powder the dried Trichosanthes seeds and pass t...

Embodiment 2

[0046] Aspergillus niger, Saccharomyces cerevisiae, Bacillus licheniformis: Stored on slopes at -80°C in the laboratory.

[0047] Aspergillus niger culture solution: inoculate Aspergillus niger into PDA liquid medium, culture at 27°C for 6 days, pick the culture solution and add 0.1% Tween-80 at a mass ratio of 1:10 to elute spores to obtain Aspergillus niger culture solution; Yeast culture medium: inoculate Saccharomyces cerevisiae into YPD liquid medium, culture at 30°C, 180rpm for 13 hours to obtain Saccharomyces cerevisiae culture medium; Bacillus licheniformis culture medium: inoculate Bacillus licheniformis into liquid LB medium, 33°C, 180rpm Shake culture for 17 hours to obtain Bacillus licheniformis culture solution.

Abstract

The invention relates to the field of breeding of beef cattle and specifically relates to a preparation method of beef cattle feed. The beef cattle feed is characterized in that pine needle meal containing multiple nutritional components, such as lipid substances, nitrogen containing compounds, coarse fibers, soluble carbohydrate, mineral substances, vitamin C, vitamin E and carotene A, is added to the beef cattle feed; corydalis tuber can enhance the stress resistance ability of the beef cattle and reduce stressors; the added trace elements supplement the beef cattle with nutrients required in a growing process and enhance immunity; the added garlic skin and garlic stems containing garlicin can enhance gastric secretion and gastrointestinal peristalsis of the beef cattle, stimulate appetite and promote digestion, thereby promoting growth of the beef cattle; the garlicin has obvious inhibiting and killing effects on harmful bacteria, but has no inhibiting or killing effects on most ofbeneficial bacteria, thereby preventing and treating multiple diseases and improving the immunity of the beef cattle; and the added brewer's grains emit a unique fragrance and enable the beef cattle to generate appetite immediately and ingest the feed rapidly, thereby enhancing the palatability of the feed and achieving the effects of attracting and increasing feed intake.

Description

technical field [0001] The invention relates to the field of beef cattle feeding, in particular to a method for preparing beef cattle feed. Background technique [0002] With the rapid development of economy and society, people's demand for beef and its products is increasing, which brings huge business opportunities to beef cattle breeding enterprises. [0003] Beef is rich in protein, amino acids, and trace elements, and has high nutritional value. It has become one of the daily meats consumed by consumers. The gradual increase in beef consumption has driven the development of the breeding industry. The amount of cattle breeding is increasing. The larger the size, the current cattle farms add a variety of drugs to promote the growth of beef cattle or enhance body resistance, including some hormones or antibiotics, in order to speed up the growth of beef cattle and pursue greater economic benefits. Some drugs will remain in the beef cattle within a certain period of time, ...
