Embodiment 1

[0035] A preparation method for probiotics for laying hens, comprising the following steps:

[0036] (1) The strains of Lactobacillus plantarum and Bacillus subtilis are enriched and cultured in a fermenter respectively and then mixed to obtain a mixed bacterial liquid;

[0037] (2) Fully mix the mixed bacterial liquid with the aqueous solution containing pectin, Tween 80, glycerin, mannitol, trehalose and sodium bicarbonate according to the same volume, and make microencapsulated live bacterial powder after spray drying (See Figure 9 ); the mass percentages of pectin, Tween 80, glycerin, mannitol, trehalose, and sodium bicarbonate in the aqueous solution are respectively 0.5-1%, 0.8-1.5%, 0.8-1.2%, 0.5-1%, 3 -6%, 2-3.5%;

[0038] (3) Uniformly mixing the microencapsulated live bacteria powder with selenized carrageenan, zinc methionine and auxiliary materials to prepare a microecological preparation for laying hens.

[0039] Each gram of the probiotics for laying hens con...

Embodiment 2

[0046] After mixing the liquid fermented product of Lactobacillus plantarum and Bacillus subtilis cultured in the fermenter in proportion, with 0.5% pectin, 0.8% Tween 80, 0.8% glycerin, 0.5% mannitol, 6% trehalose and 3.5 After the solution of % sodium bicarbonate was fully mixed according to the same volume, it was spray-dried to make live bacteria powder, and then the bacteria powder was evenly mixed with selenized carrageenan, zinc methionine and glucose to obtain a microecological preparation for laying hens. After testing, it was shown that each gram of probiotics contained 250 million Lactobacillus plantarum, 1 billion Bacillus subtilis, and the contents of selenized carrageenan and zinc methionine were 0.5% and 3% respectively. Add the prepared probiotics into the basal ration at a ratio of 1%, and feed it to laying hens after thorough stirring.

[0047] The experiment selected two cage-raised laying hens, each with 10,000 chickens, and divided them into a control grou...

Embodiment 3

[0065] After mixing the liquid fermented product of Lactobacillus plantarum and Bacillus subtilis cultured in the fermenter in proportion, with 1% pectin, 1.5% Tween 80, 1.2% glycerin, 1% mannitol, 3% trehalose and 2 After the aqueous solution of sodium bicarbonate is fully mixed by the same volume, live bacteria powder is made after spray drying, and then the bacteria powder is mixed with selenized carrageenan, zinc methionine and glucose. It contains 500 million Lactobacillus plantarum, 2.5 billion Bacillus subtilis, 1.2% selenized carrageenan and 1.5% zinc methionine. The prepared probiotics were added to the basal diet at a ratio of 1%, and fed to laying hens after thorough stirring.

[0066] After tissue and cell damage, in addition to activating neutrophils and macrophages to cause the release of products such as arachidonic acid and prostaglandins and the production of oxygen free radicals, it can also stimulate monocytes to release TNF-a and other inflammatory cells f...

Abstract

The invention discloses a preparation method for microecologics for laying hen feeds and application of the microecologics. The microecologics is prepared by uniformly mixing living microcapsules bacterium powder with selenium carrageenan, zinc methionine and auxiliary materials through a spray drying technology, wherein living microcapsules bacterium powder is obtained by uniformly mixing lactobacillus plantarum and bacillus subtilis strains with an aqueous solution containing pectin, tween-80, glycerinum, mannitol, trehalose and sodium bicarbonate after the lactobacillus plantarum and the bacillus subtilis strains are subjected to enrichment culture. The microecologics can be stored under a normal-temperature condition and is high in enteric solubility and biological adhesive. On the basis of normal daily ration, the laying hens are also fed with the microecologics, so that the anti-oxidization capability of organ bodies of laying hens can be improved; therefore, the damage degree of fallopian tubes of the laying hens in the later period of laying is reduced, excessive release of inflammatory factors in tissues can be suppressed, and the injury caused by inflammatory reaction can be alleviated; the activity and the completeness of organ tissues and cells can be guaranteed, the organ health is retained, and the productivity is improved.

Description

technical field [0001] The invention specifically relates to a microecological preparation for laying hens and a preparation method thereof, belonging to the field of microecological preparations. Background technique [0002] Eggs are an important source of protein for human beings, and are deeply loved by consumers at home and abroad. For a long time, in order to increase egg production and maximize economic benefits, laying hen breeders have generally adopted high-density cage feeding methods, which lead to lack of exercise, decreased immune resistance, and increased stress in laying hens. The unbalanced protein ratio can easily cause pathological changes in the tissues and organs of laying hens. The health of laying hens is the foundation for them to exert their production performance and maximize their benefits. [0003] Relevant studies have shown that peroxidation often occurs during the laying process of laying hens, such as lipid peroxidation destroys the integrit...
