Embodiment 1

[0019] Embodiment 1: A kind of feed of the present invention for producing pork rich in omega-3 fatty acids, adding 10% oil content > 36% to 45% in the compound diet, wherein unsaturated fatty acid > 80%, linolenic acid > 40% flaxseed, and at the same time, add VE200 / kg to the diet, and then add 1% of the Chinese herbal medicine made of Ligustrum lucidum and Astragalus in a ratio of 1:1.

[0020] A preparation method for producing pork feed rich in omega-3 fatty acids, the steps are as follows:

[0021] Step 1: Screening of flaxseed

[0022] The oil content of linseed is screened out > 36%, among which the unsaturated fatty acid reaches > 80%, and the linolenic acid > 40%, to remove impurities;

[0023] Step 2: Selection of VE

[0024] Choose dl-a-tocopheryl acetate, the activity is 50%;

[0025] Step 3: Preparation of compound Chinese herbal medicine

[0026] Astragalus membranaceus and Ligustrum lucidum were dried (60-65°C) and pulverized, passed through a 40-mesh sieve,...

Embodiment 2

[0032] Embodiment 2: the present invention adds 10% linseed (oil content > 36%~ 45%, of which unsaturated fatty acid > 80%, linolenic acid > 40%). At the same time, VE200 / kg was added to the diet. Then add 1% Chinese herbal medicine (coordinated by Ligustrum lucidum and Radix Astragali at a ratio of 1:1. Free feeding, feed to slaughter in the form of powder. Compared with the traditional diet of conventional corn soybean meal, it can improve pig muscle Fat, back fat, abdominal fat, heart and liver fat omega-3 fatty acids 3-7 times. Feeding omega-3 fatty acid-rich pork or lard to rats compared with feeding saturated fatty acid pork or lard, It can reduce the content of low-density lipoprotein cholesterol in rat serum, which is of great significance to the prevention of cardiovascular and cerebrovascular diseases. At the same time, it can improve the antioxidant capacity of rat heart and liver tissue.

Abstract

The invention provides a feed for pork rich in omega-3 fatty acid and a preparation method thereof, which is characterized in that the feed improves omega-3 fatty acid content ratio in pig intramuscular fat, back fat, abdomen fat as well as heart and liver fat for 3-7 times, and pork rich in omega-3 fatty acid is not easy to oxidize and has long storage time. The feed is prepared by the following componets 10% of flaxseed, VE 200 / kg diet and 1% of Chinese herbal medicine are added in formulating diet, wherein the Chinese herbal medicine is prepared by fructus ligustri lucidi and Astragalus mongholicus at the ratio of 1: 1. The method comprises the following steps: screening flaxseed, selecting VE, preparing compound Chinese herbal medicine, providing a diet formula, and preparing diet. The feed disclosed by the invention can improve omega-3 fatty acid content ratio in pig intramuscular fat, back fat, abdomen fat as well as heart and liver fat for 3-7 times, and pork rich in omega-3 fatty acid is not easy to be oxidized and has long storage time.

Description

(1) Technical field [0001] The invention relates to animal science, in particular to a feed for producing pork rich in omega-3 fatty acids and a preparation method thereof. (2) Background technology [0002] In recent years, scientists have discovered that omega-3 fatty acids are essential fatty acids for the human body. They play an important role in preventing and treating cardiovascular and cerebrovascular diseases, promoting brain growth and development, and improving the body's immunity. They are important substances for maintaining human evolution, health and longevity. When there are enough omega-3 fatty acids in the human body, it can effectively resist the invasion of the following diseases: senile dementia, mental retardation, low memory, immune diseases, etc.; at the same time, it can remove blood vessel "garbage", improve blood vessel elasticity, and effectively prevent heart disease. Cerebrovascular disease. The human body cannot synthesize omega-3 fatty acids,...
