Pig feed for producing pork product rich in n-3 polyunsaturated fatty acids and preparing method and using method of pig feed

Abstract

The invention provides a pig feed for producing a pork product rich in n-3 polyunsaturated fatty acids and a using method of the pig feed. The feed is composed of a feed A and a feed B. The feed A is prepared from 3-6% of flaxseed meal, 44-50% of corn, 6-9% of bean pulp, 15-25% of wheat, 10-15% of bran, 4-6% of defatted rice bran and 4% of premix. The feed B is prepared from 44-50% of corn, 6-9% of bean pulp, 15-25% of wheat, 1-3% of soya-bean oil, 10-15% of bran, 4-6% of defatted rice bran and 4% of premix. By the adoption of the pig feed, the pork product can be rich in n-3 polyunsaturated fat, n-6 / n-3 is between 2:1 and 8:1, meat color and marbling score is between 3 and 4, the pork product is healthy and high in quality, and a key feeding method for producing the pork product is provided for feeders.

Description

technical field [0001] The invention belongs to the field of animal husbandry and breeding, and in particular relates to pig feed for producing pork products rich in n-3 polyunsaturated fatty acids and a use method thereof. Background technique [0002] Pork is the most important meat product on the table of Chinese people, and its quality directly affects the health of the people. With the improvement of people's living standards, the consumption of pork is also increasing, but excessive consumption of pork products with unreasonable fatty acid composition will lead to a series of health problems, such as high blood fat, high cholesterol, heart disease and so on. The FDA recommends that n-6 / n-3 in healthy pork suitable for human consumption be at a ratio of 5:1 to 10:1 or lower, while the ratio of normal pork is much higher than this. Although there are methods to reduce the ratio of n-6 / n-3 at home and abroad, there are certain defects. In addition, blindly pursuing the ...

Problems solved by technology

In addition, blindly pursuing the n-6 / n-3 ratio can lead to pork becoming soft and yellow, reducing the antioxidant capacity and water retention capacity of pork, which will not only reduce the purchasing power of consumers, but also shorten the shelf life, thereby affecting the economic value (D 'Arrigo et al., 2002; Nguyen et al., 2004; Guillevic et al., 2009)

[0003] In view of the above problems, a patent study shows that by adding Chinese herbal medicines, flaxseed can be used as a feed additive to improve pig fat metabolism and carcass quality. )

And in another patent (CN101731479A) 10% linseed is used, its main effect is to increase the n-3 fatty acid content in pork by 3 to 7 times, but does not mention the change of the n-6 / n-3 ratio, and There is no clear requirement on the quality of its key raw material linseed

Another study can reduce the n-6 / n-3 in pork to the standard of healthy pork by changing the composition of the diet, but there is no research on the tenderness and marbling score of the meat
