[0046] Example 1 Production of black-cap pig pork rich in n-3 PUFA and low in n-6 PUFA / n-3 PUFA with the oil-added ration of the present invention

[0047] 1. Materials and methods

[0048] 1.1 Diets during the fattening period

[0049] The fattening period diet is divided into 4 kinds: the fattening period ordinary diet (referred to as the control diet), 0.7% diet (add 0.7% linseed oil and 2.3% soybean oil on the basis of the fattening period ordinary diet), 1.5% daily diet 2.85% ration (add 2.85% linseed oil and 0.15% soybean oil to the normal ration during the fattening period). Among them, in the normal diet during the fattening period, the crude fiber content was 11.5%-12.9%, the crude protein content was 10.86%-12.58%, PUFA accounted for 48.56% of the total fatty acid mass, and n-3 PUFA accounted for 1.69% of the total fatty acid mass. The mass ratio of n-6 PUFA to n-3 PUFA was 27.71%.

Abstract

The invention discloses an oil-added daily ration and a method for producing pork rich in n-3 PUFA and low in n-6/n-3 PUFA. Wherein the oil-added daily ration is obtained by adding 0.70%-2.85% by massof linseed oil and 0.15%-2.30% by mass of soybean oil into a common daily ration; in the oil-added daily ration, the content of crude fiber is 11.5%-12.9% by mass, the content of crude protein is 10.86%-12.58% by mass, PUFA accounts for 51.77%-52.71% by mass of total fatty acid, and n-3 PUFA accounts for 6.15%-13.58% by mass of total fatty acid, wherein the mass ratio of the n-6 PUFA to the n-3 PUFA is 2.87 to 7.56. Aiming at the characteristic of disproportionality of fatty acid in pork, according to the principles and technologies of animal nutrition and animal physiology, the coarse feed tolerance characteristic of the Shandong Zaozhuang Heigai pigs is fully utilized; the daily ration which is high in crude fiber content and low in crude protein content and contains linseed oil and soybean oil in different proportions is designed to produce the high-quality Heigai pig pork which is rich in n-3 PUFA and low in n-6 PUFA/n-3 PUFA, and the method has important significance in improvingthe industrial value of the Heigai pig and improving the dietary health of human beings.

Description

technical field [0001] The invention relates to an oil-added ration and a method for producing pork rich in n-3 PUFA and low in n-6 / n-3 PUFA, belonging to the field of animal nutrition and feed science. Background technique [0002] The intake of PUFA and the ratio of n-6 / n-3 PUFA are closely related to the occurrence and development of diseases such as cardiovascular disease, obesity, tumor and diabetes, and the ratio of n-6 / n-3 PUFA is less than 4:1, which is beneficial to human health , but currently the ratio of n-6 / n-3 PUFA in people's diet is relatively high, even as high as 10:1 ~ 30:1. Pork is the most important source of animal protein for Chinese consumers, and its quality and safety are closely related to human health. The content of saturated fatty acid (SFA) and monounsaturated fatty acid (MUFA) in pork is relatively high, and PUFA is relatively deficient, especially the content of n-3 PUFA is low, and the ratio of n-6 / n-3 PUFA is high, generally 14~ 28.
