preparation example Construction

[0022] A preparation method of asparagus straw extract feed additive, the specific steps are as follows:

[0023] Step 1. Pick up the raw fresh asparagus stalks and cut them into 6-8 cm pieces;

[0024] Step 2. Put the raw material into a multifunctional extraction tank, boil it for 3 hours with 4 times the amount of water, and filter with a steam pressure of 0.1Mpa to obtain the first filtrate and filter residue. The filtrate is continuously concentrated to obtain a concentrated solution;

[0025] Step 3. The filter residue is again subjected to twice the amount of water, boiled for 2 hours, treated with a steam pressure of 0.1MPa, and filtered to obtain the second filtrate and filter residue respectively; the filter residue is discarded;

[0026] Step 4. Mix and concentrate the first filtrate and the second filtrate to a weight ratio of 1:4 to obtain the asparagus straw fruit extract.

[0028] Step 5. Put the extract into a container, and store it under refrigeration at...

Embodiment 1

[0036] During the period from 2011.04.18 to 2011.05.19 in the local chicken breeding center of Jiangxi Province, the experimental animals used 26-week-old Yugan black-bone chicken during the laying period. A control addition experiment was carried out, and the results are as follows:

[0037] Test index test group Control group Significance Egg production rate (%) 67.72±2.45 47.27±1.22P <0.05

Total superoxide dismutase (U / ml) 159.72±10.62 114.09±11.16P <0.01

IgG(mg / dl) 0.76±0.11 0.39.05±0.05P <0.01

IgM(mg / dl) 0.67±0.02 0.41±0.05P <0.01

Alanine aminotransferase (U / L) 4.40±1.91 11.71±1.50 P <0.01

[0038] Conclusion: 1. Increase egg production rate and improve production performance;

[0039] 2. Anti-oxidation, anti-stress, improve animal body's own immunity.

[0040] When used, you can drink water or mix ingredients. When drinking water, add 5g per kg of water; when mixing, add 1-2kg per 1000kg of compound feed.

Abstract

The invention discloses an asparagus straw extract feed additive and a preparation method thereof. The asparagus straw extract feed additive is obtained by the steps of smashing asparagus straw, carrying out circulation extraction on the smashed asparagus straw repeatedly and uniformly mixing with a carrier. The preparation method of the additive comprises the following steps of: step one, primarily extracting the asparagus straw; and step two, carrying out secondary circulation extraction on residues left after the extraction in the step one, carrying out spray drying on extracts obtained through extraction in the two steps, and uniformly mixing the extracts with the carrier to form the asparagus straw extract feed additive. The asparagus straw extract feed additive disclosed by the invention has the advantages of improving laying rate, resisting against oxidation and stress and enhancing animal immunity.

Description

Technical field [0001] The invention relates to an asparagus straw extract feed additive and a preparation method thereof. It has the functions of increasing egg production rate, anti-oxidation, anti-stress and enhancing animal immunity, and belongs to the technical field of natural plant additives. Background technique [0002] With the rapid development of the feed additive industry, the harm caused by chemical additives has become a consensus, such as drug residues, drug resistance, carcinogenicity, teratogenicity, mutagenesis and other side effects, so people have to carefully consider when choosing additives. However, with the development of multiple disciplines such as animal nutrition, physiology, feeding science, and biochemistry, the current feed additives have integrated multiple disciplines and new technologies, and their functions and applications have also been further expanded. Among them, Chinese herbal medicine as a feed additive or mixed feeding medicament is bei...
