Embodiment 1

[0022] Mixed feed for laying hens, including: dietary raw materials, microbial additives and folic acid.

[0023] Specific preparation method: Weigh ration feed: 60kg of corn, 23kg of soybean meal, 10kg of bran, 8kg of stone powder, 5kg of premix, 2kg of chlorella, mix and stir evenly;

[0024] The proportion of microbial feed additives added to the diet raw materials was 200:1.

[0025] The preparation method of microbial additive is:

[0026] a. Chlorella passed through the bioreactor in CO 2 The concentration is 15% of the volume, the pH value is 6.8, the light intensity is 6500lx, and the algae cell concentration reaches 1.0×10 7 More than cfu / ml, the chlorella nutrient solution is preliminarily prepared;

[0027] b. Add lactic acid bacteria, saccharomyces, aquatic spores, and nitrifying bacteria in the nutrient solution of chlorella with a mass ratio of 1:1:1:1, adjust the pH to 7.0, and ferment for 36 hours at a temperature of 30°C. The chlorella fermented liquid obt...

Abstract

The present invention discloses a folic acid and chlorella-containing mixed feed for laying chickens and a preparation method thereof, and belongs to the technical field of preparation of feeds. The mixed feed is prepared by mixing a daily ration composition, a micro-organism additive and folic acid; the micro-organism additive is 1-3 parts by weight; and the micro-organism additive is prepared according to the following steps: chlorella is cultured in a bioreactor at a CO2 concentration of 5-20% of a volume and a pH value of 6-8 for 36 h until chlorella cell concentration reaches 1.0 x 10<7>cfu / ml or more; a chlorella nutrient solution is preliminarily prepared; compound probiotics composed of lactic acid bacteria, yeasts, aquatic spore bacteria and nitrobacteria are added in the chlorella nutrient solution; pH is adjusted; temperature is 25-35 DEG C; fermentation is conducted for 36 h; and the materials are filtered to obtain the micro-organism additive. The mixed feed of the laying chickens integrates ratio needs of high proteins, high minerals and high-quality vitamins, improves the immunity of the laying chickens and increases folic acid content in eggs.

Description

technical field [0001] The invention relates to the technical field of feed preparation, in particular to a mixed feed for laying hens and a preparation method thereof. Background technique [0002] Eggs are a food that people often consume and an important source of protein intake for the human body. With the improvement of people's living standards, people's demand for eggs and quality requirements also increase thereupon. Feed is an important factor affecting egg quality. [0003] At present, there are many studies on feed in the prior art. For example, application number 201711463594.X discloses a feed for laying hens, including components: 40-60 parts of corn flour; 10-15 parts of soybean meal; 4-6 parts of premix 5-15 parts of mole cricket powder; 0.1-0.5 parts of microcapsules; the core material of the microcapsules is lactic acid bacteria. Among them, the microencapsulated lactic acid bacteria can improve immunity and effectively increase the growth rate of chicke...
