Problems solved by technology

However, the fatty acids in conventionally produced duck meat are mainly composed of saturated fatty acids, the proportion of polyunsaturated fatty acids is low, and mainly n-6 polyunsaturated fatty acids, the ratio of n-6 / n-3 is relatively high, and almost does not contain EPA and functional fatty acids such as DHA

Embodiment 1

[0073] Embodiment 1, use the meat duck fattening stage feed containing seal oil of the present invention to produce functional duck meat with high content of PUFA, EPA and DHA and low n-6PUFA / n-3PUFA

[0074] 1 Materials and methods:

[0075] 1.1 Diets during the fattening period

[0076]The fattening period diet is divided into 6 types: the fattening period ordinary diet (referred to as the control diet), 0.5% diet (the diet obtained by adding 0.5% seal oil to the fattening period ordinary diet quality of the fattening period ), 0.75% diet (the diet obtained by adding seal oil that is 0.75% of the weight of the normal diet during the fattening period to the normal diet during the fattening period), 1.0% diet (adding to the normal diet during the fattening period is 1.0% seal oil of the mass of the normal ration), 1.25% of the ration (the ration obtained by adding 1.25% of the seal oil of the normal ration of the fattening period to the normal ration during the fattening peri...

Abstract

The invention discloses a feed for producing functional ducks with high PUFA (polyunsaturated fatty acid), EPA (timnodonic acid) and DHA (docosahexaenoic acid) content and low n-6 PUFA / n-3 PUFA. The feed is meat duck feed containing seal oil which is used in a fattening period and formed by a common feed in a duck fattening period and the seal oil; the quality of the seal oil is 0.5%-1.5% of that of the common feed in the duck fattening period; and the common feed in the duck fattening period does not contain the seal oil. According to the characteristics of low content and ratio imbalance of PUFA in meat ducks and principles and technologies of zoonomy and animal nutrition, the seal oil is taken as an additive to improve the fatty acid component of the daily ration of the meat ducks and enhance the enrichment degree of the PUFA in the meat ducks, thereby producing the functional ducks with high PUFA content, high EPA content, high DHA content and low n-6 / n-3 PUFA ratio.

Description

technical field [0001] The invention relates to a meat duck feed, in particular to a feed for producing functional duck meat with high content of PUFA, EPA and DHA and low n-6PUFA / n-3PUFA. Background technique [0002] With the improvement of people's living standards, the proportion of meat in people's diet continues to increase, and a large amount of fat is obtained therefrom. The fatty acids that make up animal fat can be roughly divided into saturated fatty acids and unsaturated fatty acids according to their degree of saturation and nutritional functionality, and unsaturated fatty acids can be divided into monounsaturated fatty acids and polyunsaturated fatty acids according to their degree of unsaturation. Modern food nutrition research shows that the content of polyunsaturated fatty acids in the diet is closely related to the health of the human body, and the role of n-3 polyunsaturated fatty acids is particularly prominent. Increase the intake of n-3 polyunsaturated ...
