Problems solved by technology

[0003] my country produces a large amount of crop wheat straw each year. Wheat straw contains active ingredients such as cellulose, hemicellulose, and flavonoids. Due to the dense structure of plant cell walls, conventional mechanical methods are difficult to effectively destroy its structure, so it cannot be effectively used by non-herbivorous animals. Except for a small part used to feed herbivorous livestock or return to the field, most of them are used for natural corrosion or burning, resulting in waste of resources and environmental pollution

Embodiment 1

[0016] The wheat straw was shredded into pieces with a length of 2 cm, a width of 1 cm and a thickness of 2 cm, and the wheat straw was mechanically activated by a three-dimensional mill. The activation time was 3 minutes, and the grain size of the wheat straw was 250 mesh. The reduced sugar of the activated wheat straw is measured by conventional measurement methods in the field of feed, which is 2.5 times that of the raw material before activation; , the surface active groups of straw fiber increased significantly, and the cation exchange capacity was significantly enhanced, which was 1.5 times that of the raw material before activation. Twelve times that of the previous raw material, the water diffusibility is significantly enhanced. The prepared mechanically activated wheat straw is packaged in a woven bag with an inner film bag, sealed and stored in a ventilated, cool and dry place.

Embodiment 2

[0018] Weigh 40kg of the mechanically activated wheat straw product obtained in Example 1, 960kg of full-price feed for growing pigs (T312) produced by Shanghai Xinnong Feed Co., Ltd. In addition to the components, the crushing particle size of other feed components is 40 mesh. Mix the above-mentioned feed components for 3 minutes with a mixer, then pack them in woven bags with an inner film, and store them in a ventilated, cool and dry place after sealing.

Embodiment 3

[0020] Weigh 60 kg of the mechanically activated wheat straw product obtained in Example 1, 940 kg of full-price feed for fattening pigs (T313) produced by Shanghai Xinnong Feed Co., Ltd. Except for the corn component, the crushing particle size of other feed components is 30 mesh. Mix the above-mentioned feed components for 3 minutes with a mixer, then pack them in woven bags with an inner membrane, and store them in a ventilated, cool and dry place after sealing.

Abstract

The invention provides a method for replacing corn ingredients in pig feed. The corn ingredients are contained in the pig feed, in addition, mechanical activated wheat straws are utilized for replacing the corn ingredients accounting for 3 to 8 weight percent of the pig feed, and during the mechanical activation, a vertical mill is used for crushing the wheat straws, and the crushing time is 1 to 3 minutes. The reducing sugar of the mechanical activated wheat straws is obviously increased, the water-holding capacity and the expansion force are greatly enhanced, active base groups on the surfaces of straw fiber are increased, the cation exchange capability is enhanced, the enzymolysis reaction activity is enhanced, the water diffusivity is obviously enhanced, good biological activity and nutrition performance are realized, and feeding experiments prove that the pig feed prepared by the method has the advantages that the pig feeding quantity and the daily weight increase can be improved, the feed-weight ratio is slightly increased, and the integral feeding effect of the pig is improved. The method provided by the invention has the advantages that the effects of efficiently utilizing crop wastes of wheat straws and changing the wheat straws into feed are realized, and the feed cost can be reduced.

Description

technical field [0001] The invention relates to the field of feed, in particular to a method for replacing corn components in pig feed with mechanically activated wheat straw. Background technique [0002] Corn accounts for more than 50% of pig feed components. In recent years, due to the rapid development of the feed industry and the continuous enhancement of corn deep processing capabilities, my country has transformed from a net exporter of corn to a net importer. The rapid rise in corn prices directly leads to feed The pressure of industrial costs is increasing, and the price of pork is soaring. The development of my country's feed industry has entered a development period of comprehensive resource constraints, and the problem of insufficient supply of raw material resources has become prominent. [0003] my country produces a large amount of crop wheat straw each year. Wheat straw contains active ingredients such as cellulose, hemicellulose, and flavonoids. Due to the de...
