Problems solved by technology

Although the selection and promotion of "double-low" rapeseed varieties with low erucic acid and low glucosinolates has been popularized in recent years, tannin, glucosinolates, and erucic acid are still the three main anti-nutrients in rapeseed after oil extraction. factor, which limits the utilization of rapeseed meal in feed, and as a local dominant protein feed resource, it has great development and utilization value in terms of nutrition and functionality

[0039] 1) Preparation of fermented yeast liquid:

[0040] ①Mix 0.1% of the strains prepared in step ④ of the preparation of fermented rapeseed meal with 0.3-0.5% conditioner and 10% corn flour, wherein the conditioner consists of 0.1-0.3% potassium chloride, 0.5 -1.5% ammonium sulfate, 0.05-0.1% magnesium sulfate, 0.1-0.3% edible glucose monohydrate and appropriate amount of heavy calcium powder carrier;

[0041] ② After mixing, put it into the corresponding amount of clean drinking water and stir evenly, such as 0.1 kg of liquid bacteria, 0.3 kg of conditioner and 10 kg of corn flour into 100 kg of water. Put the above mixed suspension into a corresponding container and seal it away from light for anaerobic fermentation for 4-7 days. The temperature is controlled at 25-35°C, and the gas needs to be exhausted once the next day. After the fermentation is completed, it is ready for use, and the pH value is about 3.5-3.8.

Abstract

The invention provides a broiler feed prepared from fermented rapeseed meal and a preparation method of the broiler feed. The broiler feed prepared from the fermented rapeseed meal comprises the components of not less than 10% of fermented rapeseed meal, corn, 0.5-1.0% of a mother liquor of fermentation strains, and / or soybean meal, and / or wheat bran, and / or fine rice bran, wherein the fermented rapeseed meal comprises 92-95% of rapeseed meal, 1-2% of a conditioning agent, 0.3-0.5% of strains and 3-5% of corn flour or fine rice bran. The content of glucosinolate in the fermented rapeseed mealprepared by anaerobic fermentation of the rapeseed meal is reduced by over 70% and the content of tannin is reduced by over 50% in comparison with those in rapeseed meal. After a high-quality broilercompound feed free of a medicine additive prepared by combination of the fermented rapeseed meal and the raw materials, such as the corn, the soybean meal and the wheat bran and then secondary fermentation is fed to broilers, the intestinal immunity and a blood IgG index are significantly improved, and the chicken freshness indexes, such as inosinic acid are significantly improved.

Description

technical field [0001] The invention relates to a broiler feed and a preparation method thereof, in particular to a high-quality broiler feed prepared by fermented rapeseed meal and a preparation method thereof. Background technique [0002] my country's modern animal husbandry has entered an important period of upgrading and transformation, and the development of the entire industry is changing from quantitative to quality. At present, people's consumption demand for high-quality flavored livestock products is also showing a rapid growth trend, and my country's feed industry will completely ban the use of pharmaceutical additives such as antibiotics in feed products from July 1, 2020, which has played a role in promoting this transformation. effect. [0003] At present, the market demand for high-quality broiler chickens with good taste and flavor and green and healthy production mode is increasing, and at the same time, there is an increase in the demand for related feed p...
