Problems solved by technology

[0007] At present, there is a method of adding 3% to 5% deep-sea fish oil to pig feed to produce pork with high PUFA. This method is expensive, and the pork has a fishy smell and poor palatability.
[0008] So far, there is a lack of a low production cost, which can effectively increase the content of po

Abstract

The invention discloses pig feed for improving a content of polyunsaturated fatty acid in pork and a method for preparing the same. The pig feed comprises the following components in part by weight: 32 to 60 parts of corn, 16 to 30 parts of bean pulp, 10 to 20 parts of wheat middling, 10 to 20 parts of wheat bran, 5 to 12 parts of detoxicated flaxseed, 1 to 4 parts of grease, 0.2 to 0.5 part of common salt, 0.4 to 1.2 parts of calcium hydrogen phosphate, 0.4 to 1.5 parts of calcium powder, 0.3 to 1 part of lysine sulfate, 0.05 to 0.2 part of choline chloride, 0.1 to 0.5 part of trace element additive, 0.01 to 0.06 part of compound vitamin, and 0.015 to 0.03 part of yeast selenium. The pig feed has the advantages that: the detoxicated flaxseed is used as a main source of PUFA in the feed, so that the production cost is low; the ratio of omega-3 to omega-6 in the pork is reasonable, so the physiological needs of the human body are met; and the pork tastes good, is good in meat quality and is free of fishy smell, and the drip loss is little.

Description

technical field [0001] The invention relates to a pig feed, in particular to a pig feed that increases the content of polyunsaturated fatty acids in pork. The invention also relates to a preparation method of the pig feed, which belongs to the field of animal feed. Background technique [0002] Polyunsaturated fatty acids (PUFA) are fatty acids containing 2 or more double bonds. Generally, the double bonds of natural fatty acids exist in the form of cis. Polyunsaturated fatty acids can be divided into omega-6 and omega-3 polyunsaturated fatty acids according to their structure. ω-6PUFA can be: linoleic acid, γ-linolenic acid or arachidonic acid, among which linoleic acid is synthesized by plants and supplied to the human body through food, it is necessary to maintain human health, so it is called "essential fatty acid" ". As long as a sufficient amount of linoleic acid can be supplied, the human body can synthesize other omega-6 fatty acids needed. ω-3PUFA means that sta...
