Wheat type fattening pig feed capable of reducing ratio of omega-6/omega-3 polyunsaturated fatty acids in pork and application of wheat type fattening pig feed

Abstract

The invention relates to a wheat type fattening pig feed capable of reducing the ratio of omega-6 / omega-3 polyunsaturated fatty acids in pork and application thereof, and the feed comprises the following components in parts by weight: 50-65 parts of wheat, 10-15 parts of rice bran, 8-12 parts of wheat bran, 4-8 parts of puffed flaxseeds, 8-12 parts of corn germ meal, 0.3-0.5 part of sodium chloride, 0.4-1.2 parts of calcium hydrophosphate, 0.4-1.5 parts of stone powder, 0.3-1 part of L-lysine hydrochloride and 0.1-0.2 part of choline chloride. The feed is prepared from the following raw materials in parts by weight: 0.03-0.05 part of a compound antioxidant, 0.03-0.05 part of compound non-starch polysaccharide enzyme, 0.2-0.4 part of a microelement additive and 0.2-0.4 part of a compound vitamin additive. The feed takes wheat as a main energy source, so that the cost is saved; by using the composite non-starch polysaccharide enzyme, the digestion and utilization rate of the pigs on the wheat is effectively improved. Compared with the prior art, the feed has the advantages that the ratio of omega-6 / omega-3 polyunsaturated fatty acids in pork can be reduced, the absorption and utilization rate of wheat daily ration can be improved, and the production performance can be improved; and the preparation method is simple and low in production cost.

Description

technical field [0001] The invention belongs to the technical field of animal feed, and relates to a wheat-type fattening pig feed for reducing the ratio of ω-6 / ω-3 polyunsaturated fatty acids in pork and an application thereof. Background technique [0002] Omega-6 polyunsaturated fatty acids (ω-6PUFA) and ω-3 polyunsaturated fatty acids (ω-3PUFA) are indispensable essential fatty acids for animals, which cannot be synthesized by the body itself and must be obtained from food. The two share the same set of enzymes. When there are too many omega-6 polyunsaturated fatty acids in the body, it will affect the conversion of omega-3 polyunsaturated fatty acids in the body. The content of omega-3 polyunsaturated fatty acids in the daily diet is relatively high. Low, but high in omega-6 polyunsaturated fatty acids. Intake of foods high in omega-3 polyunsaturated fatty acids and maintaining the intake balance of omega-6 and omega-3 polyunsaturated fatty acids are of great significa...
