Brewer's grain fermented feed and preparation method thereof

Abstract

The invention relates to a brewer's grain fermented feed which comprises the following components: 65-70 parts of brewer's grain, 5-10 parts of dried orange peel, 20-30 parts of apple pulp and 0.5 part of composite liquid strain. The composite liquid strain comprises lactobacillus, Bacillus and yeast. By adding the orange peel and apple pulp into the feed, the orange peel is the waste of fruit juice squeezing, and the apple pulp is the pomace of pectin extraction; and the orange peel, apple pulp and brewer's grain are used as the raw materials and fermented to prepare the animal feed, thereby increasing the nutrient content of the feed, and performing the function of waste utilization. The orange peel added into the feed has the effects of stimulating the appetite, regulating the flow of qi, strengthening the spleen and resolving stagnation, is beneficial to feed digestion and absorption of animals, is beneficial to lactation of dairy cows and farrowing sows, and is capable of preventing galactostasis and enhancing the milk yield. The orange peel is rich in vitamin C, flavonoids and carotin, is a natural antioxidant, and can prevent the feed from deterioration.

Description

technical field [0001] The invention relates to the field of animal feed processing, in particular to a feed using brewer's grains as a raw material and a preparation method thereof. Background technique [0002] Brewer's grains, the main by-product of the beer industry, are the residue after fermenting and extracting the soluble carbohydrates in the seeds with barley as the raw material. About 1 / 4t of brewer's grains are produced for every 1 ton of beer produced. The annual output of brewer's grains in my country has reached more than 10 million tons, and it is still increasing. Brewer's grains are rich in protein, amino acid and trace elements. At present, it is mostly used for feeding. [0003] Feeding distiller's grains to livestock such as pigs and cattle is a conventional utilization method of distiller's grains. However, after the distiller's grains are placed in the air for a certain period of time, the oxidation of microorganisms such as acetic acid bacteria (dis...

Problems solved by technology

However, the fermentation process takes a long time, and the entire fermentation process takes more than a month.

However, the fermentation of feed itself will take up a lot of space and equipment. If the fermentation cycle is too long, the cycle of production equipment will be too slow and the production efficiency will be low, which will undoubtedly increase the cost of production.
