A pig feed for producing healthy pork rich in α-linolenic acid and its application method

Abstract

The invention provides a pig feed, comprising: 60wt%-75wt% of barley, 7wt%-15wt% of linseed, 0.02wt%-0.05wt% of coated cysteamine, 0.02wt%-0.05wt% of vitamin E. 0.01wt% to 0.05wt% of Acto. The pig feed provided by the invention has no significant impact on carcass shape and meat quality traits, but can improve meat color, and does not produce significant changes to the amino acid content of the body; it can promote the deposition of PUFA in the body and significantly reduce the ratio of S / U (saturated fatty acid / unsaturated fatty acid) Ratio; significantly increased the content of α-linolenic acid in pork; enhanced the deposition of ω-3 PUFA, decreased the ratio of ω-6:ω-3 PUFA and cholesterol content; the addition of barley had a positive effect on the improvement of meat quality. Simultaneously, the present invention also provides the key feeding method for producing the above pork products.

Description

technical field [0001] The invention belongs to the technical field of animal feed, and in particular relates to a feed for producing healthy pork rich in α-linolenic acid and an application method thereof. Background technique [0002] With the development of social economy and the improvement of people's living standards, people's consumption of meat has changed from the demand for quantity to the demand for quality. In the last hundred years, due to the increase in the intake of oil rich in ω-6PUFA (polyunsaturated fatty acid), the value of ω-6:ω-3PUFA in the diet has increased from the original (1~2):1 to ( 5-50):1, such as (20-30):1 in the modern western diet. Reducing the value of ω-6:ω-3 PUFA in the diet can reduce the occurrence of many chronic diseases, and the recommended ratio is less than 4.0. [0003] The balance of ω-6 and ω-3 PUFA plays an important role in the stability and normal growth of the internal environment of the body, and can reduce the occurrence...

Problems solved by technology

However, the patent shows that the crude fat content of the flaxseed meal used is ≥35%, and the linolenic acid content is ≥65%, and its nutritional level is unreasonable and needs to be discussed

In addition, flaxseed meal may contain many toxic substances and anti-nutritional factors, such as flaxseed gum, phytic acid, allergens, cyanogenic glycosides, trypsin inhibitors, anti-VB 6 Factors, etc., especially the toxicity of cyanogenic glycosides, will limit its use in feed; and the use period of linseed meal feed products in the patent is from 60kg of pig weight to 20 days before sale, and the use period is limited, which may affect Optimal deposition of PUFA in tissues of growing-finishing pigs
