Embodiment 1

[0033] 1. After pulverizing 200g of guar soybean meal, pass it through a 20-mesh analytical sieve, then sterilize at 121°C for 30 minutes, and cool it for later use; another 200g of guar soybean meal is directly sterilized at 121°C for 30 minutes without crushing, and cool it for later use.

[0034] 2. Seed cultivation:

[0035] a. Preparation of seed medium: take 3% soybean meal, 1% glucose and tap water, sterilize at 121° C. for 30 minutes, and cool for later use;

[0036] b. Cultivation of Lactobacillus plantarum and Streptococcus faecalis: Take out the frozen glycerol tube strains of Lactobacillus plantarum and Streptococcus faecalis from the refrigerator. In the Erlenmeyer flask, culture at 40°C for 12 hours.

[0037] c. Culture of Saccharomyces cerevisiae:

[0038] Activation of active dry Saccharomyces cerevisiae starts 1 hour before inoculation: the amount of yeast used is 0.02% of the fermentation material, activated with 2% sugar aqueous solution at 40°C for 1 hour...

Embodiment 2

[0065] Experimental investigation was carried out on the protein feed added with the additive, and the production indicators such as the feed intake, egg production rate, egg weight, eggshell color, morbidity rate and death rate of laying hens at the peak laying period of the additive were investigated. Impact.

[0066] The protein feed, including the compound feed, also contains 3-5% of the additive by weight percentage.

[0067] The compound feed is 846s, provided by Haian Yuanyao Feed Co., Ltd.

[0068] (1) Experimental grouping: The experiment adopts single-factor experimental design, selects 360 Hainan gray laying hens that are 32 weeks old and are healthy and with similar body weight, and are randomly divided into three groups, one of which is the control group, and two groups are the experimental group, There were 120 chickens in each group, and three repetitions were set up for each experimental group. The principle of experimental design followed that the experiment...

Abstract

The invention provides a guar meal fermented protein feed additive. The content of crude protein in a guar meal fermented protein feed is 52-54wt%. The guar meal fermented protein feed additive also contains lactobacillus and saccharomyces cerevisiae, wherein the content of lactobacillus is 8.5*1010cfu / g and the content of saccharomyces cerevisiae is 4.6*106cfu / g. In comparison with the prior art, the invention has the following beneficial effects: the anti-nutritional factor oligosaccharide in guar meal can be almost completely degraded; the additive mainly contains micromolecular proteins and simultaneously contains a certain amount of lactobacillus plantarum, saccharomyces cerevisiae and streptococcus faecalis so as to obviously raise the nutritional value of the additive and promote animal digestion and absorption. The additive provided by the invention is added into laying hen mixed feed and used for a laying hen nursing experiment. The result shows that the additive can be used to obviously reduce feed-egg ratio, decrease production cost and raise economic benefit.

Description

technical field [0001] The invention relates to a fermented protein feed additive and a preparation method thereof, belonging to the field of microbial technology application. Background technique [0002] Protein feed is one of the important raw materials necessary for the development of animal husbandry. As a new type of protein feed raw material, guar soybean meal can alleviate the adverse effects of insufficient domestic protein feed resources and high soybean meal prices on the feed industry and animal husbandry. At present, guar soybean meal is also used in countries such as India, Pakistan and Iran as a protein feed. [0003] Guar soybean meal is a by-product of extracting bean gum from guar beans (Cyamopsis tetragonoloba), which has very high nutritional value. The amino acid components and other components it contains are shown in Table 1 and Table 2. The crude protein content of guar soybean meal is between 35-47.5%. Like all miscellaneous meals, the relative mo...
