Full-wheat type growing-finishing pigs diets and processing technique thereof

Abstract

The invention pertains to the field of feed formula design and feed processing technique, specifically relating to an all-wheat type growing and fattening pig diet and its processing technique. The inventive all-wheat type growing and fattening pig diet is composed of the following components in weight percent: 50-70 parts of all-wheat, 4-10 parts of rice bran, 10-25 parts of bean pulp, 1-5 partsof peanut meal, 0.2-1.0 parts of composite vitamins, 0.2-1.0 parts of composite trace elements, and 0.1-0.4 parts of wheat-type-specific enzyme. The processing technique adds a maturing step between the modulation step and the granulation step. By adoption of the growing and fattening pig diet, the invention has low feed cost, faster fatten pigs growth rate, shortened breeding cycle, improved fatten pigs growing production efficiency, greatly improved pig shape and carcass quality, good palatability of the all-wheat type pig diet, good pork quality (stearin meat); and the invention solves thefeed resource tensioning problem to some extent.

Description

technical field [0001] The invention belongs to the field of feed formula design and feed processing technology, and in particular relates to a whole wheat-type diet for growing and finishing pigs and a processing technology thereof. Background technique [0002] In recent years, the demand for corn as a raw material for fuel ethanol has increased significantly in the global market, which has had a crucial impact on the feed industry. Feed cost, feed raw material supply, ration formula design, etc. have all undergone great changes. The shortage or high price of corn has increased the feed cost. [0003] With the increasing shortage of corn, and in recent years, with the continuous increase of wheat production and lower price, the application of wheat in feed has become more and more extensive, and the feeding value of wheat has gradually increased. In terms of nutritional value, the metabolism of wheat The energy is 90% of corn, wheat protein is higher than corn, and some v...

Problems solved by technology

However, wheat has its particularity compared with typical energy feed corn, and its disadvantages are as follows: the application of wheat is limited by its anti-nutritional factors, and the anti-nutritional factors of wheat are mainly non-starch polysaccharides. First, wheat contains a high level of soluble Arabinoxylan and a small amount of soluble glucan can form a high-viscosity solution in the small intestine, thereby forming over-wet feces, hindering the absorption of nutrients by animals, and causing nutritional diarrhea; second, the starch structure of wheat is also different from that of corn , its starch is small granule starch, animal digestibility to non-starch polysaccharides is very low (12%), it is difficult to digest; moreover, contains higher crude fiber content in wheat, how to overcome above-mentioned wheat antinutritional factor To achieve the complete replacement of corn by wheat has become an effective measure to solve the shortage of feed resources for corn
