Embodiment 1

[0033] The preparation of embodiment 1 fermented liquid

[0034] This example only takes Lactobacillus plantarum (ACCC11016), Lactobacillus acidophilus (ACCC03955), and Candida utilis (ACCC20060) as examples to describe the specific content of the invention in detail, and does not limit the three components of the compound microbial agent of the present invention. selection of microbial sources.

[0035] (1) Activate the above-mentioned Lactobacillus plantarum (ACCC11016), Lactobacillus acidophilus (ACCC03955), and Candida utilis (ACCC20060) into their respective slant media for preservation, and culture them at 28-30°C for 24-48 hours.

[0036] Preservation of three kinds of microorganisms uses the slant culture medium formula as follows:

[0037] Both Lactobacillus plantarum and Lactobacillus acidophilus use MRS medium: 10.0g casein peptone, 10.0g beef extract, 5.0g yeast extract, 5.0g glucose, 5.0g sodium acetate, 2.0g diammonium citrate, Tween801.0 Gram, K 2 HPO 4 2.0 ...

Embodiment 2

[0043] Embodiment 2 contains the poultry feed of fermented yew poultry feed additive of the present invention

[0044] 1. The three kinds of microbial fermented liquids prepared in Example 1 are mixed uniformly according to the following proportions to become a composite microbial bacterial agent: 8L of Lactobacillus plantarum fermented liquid, 10L of Lactobacillus acidophilus fermented liquid, 12L of Candida utilis fermented liquid, after mixing Add distilled water to 50L. Among them, the effective number of viable bacteria of the three kinds of bacteria is not less than 5×10 7 individual / ml.

[0045] 2. Select 10kg of yew branches and leaves powder that has been crushed to 50 meshes and add it to the strain reaction tank, and measure its cellulose content to be 38.2g / g dry powder;

[0046] 3. Add 50L of the compound microbial agent prepared in step 1 to the reaction tank, add 500g of brown sugar and 750g of peptone at the same time, after mixing evenly, measure the polysac...

Abstract

The invention belongs to the field of biological feed, and relates to a poultry feed additive containing fermented Chinese yew, and a preparation method and applications thereof. The poultry feed additive is a dried product obtained via fermentation of Chinese yew using a compound microbial agent, and the compound microbial agent is composed of lactobacillus plantarum fermentation broth, lactobacillus acidophilus fermentation broth, and candida utilis fermentation broth. The compound microbial agent is used for biodegradation of active ingredients of Chinese yew; treatment method is mild; the active ingredients of Chinese yew are protected as far as possible; poultry absorption rate is increased; a poultry feed prepared from the poultry feed additive contains Chinese yew ingredient, lactic acid bacteria, and saccharomycetes, and is capable of increasing poultry production efficiency; a Chinese yew feed obtained via microbial fermentation is mixed with poultry daily feed at a ratio of 1 to 5%, and an obtained mixture can be used for feeding after uniform stirring.

Description

technical field [0001] The invention belongs to the field of biological feed, and relates to a poultry feed additive containing fermented yew and a preparation method and application thereof. Background technique [0002] Yew is one of the most studied anti-cancer plants in the world in recent years. It has been found through research that Taxus chinensis (mainly in the bark) contains anti-cancer active substances with a unique mechanism of action, among which paclitaxel has the strongest activity and is the only botanical drug that promotes microtubule polymerization and inhibits tubulin depolymerization. Use value has been extensively exploited. In the early days, the strong demand for paclitaxel in the pharmaceutical industry led to a large number of artificial cultivation of yews. However, due to the maturity of taxol chemical synthesis technology in recent years, the price of its plant extracts has been repeatedly reduced, and many artificially planted yews have become...
