Method for producing pig feed with deeply processed wheat by-product

Abstract

The invention provides a preparation method for producing pig feed with a deeply processed wheat by-product. The method comprises the steps that the deeply processed wheat by-product, corn, bran, bean pulp, and the like serve as raw materials; the raw materials are subjected to cleaning, crushing, blending, mixing and packaging; and then the novel pig feed that can be extensively used for nursing pigs, growing pigs, fattening pigs and sows is prepared. The method has the advantages that (1) the deeply processed wheat by-product is added; the principal component of the feed is mycoprotein; absorption and utilization of the pigs are facilitated; antinutritional factors such as non-starch polysaccharides are degraded effectively in liquefaction and saccharification procedures during deep wheat processing; the nutrition coefficient of the feed is high; (2) exogenous wheat enzyme is added; the antinutritional factors such as the non-starch polysaccharides are further degraded; the nutrition digestibility of the feed is increased; (3) exogenous lysine and bean oil are added; the defect that contents of lysine and fat in wheat serving as a raw energy material of the feed are lower is overcome; and (4) the deeply processed wheat by-product is effectively utilized, and the production cost of the feed is lowered.

Description

technical field [0001] The invention relates to a method for producing feed for livestock and poultry, in particular to a method for producing pig feed by utilizing by-products of deep processing of wheat. Background technique [0002] For a long time, corn-soybean meal rations have been adopted and promoted in pig production in most areas of my country, and corn has been used as the main energy feed for pigs. Faced with the current situation of rising corn prices, hog market and consumption level restrictions, actively seeking and developing new feed resources has become one of the hot spots in domestic hog farming. The rising price of energy feed has become the biggest unfavorable factor restricting the development of my country's pig industry. [0003] The application of foreign wheat as energy feed in pig feed has a long history. Wheat, as the main food crop in my country, contains anti-nutritional factors such as non-starch polysaccharides, and due to the uncertainty ...

Problems solved by technology

A large number of by-products, such as bran, etc. are produced during the deep processing of wheat. The comprehensive development and utilization of by-products can not only improve the economic benefits of grain processing enterprises, but also can change the current corn-soybean meal type that is currently rising in price when used in pig feed. Diet pattern has become one of the focuses of current research, but there is no report on the preparation of pig feed by the by-products of wheat deep processing
