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
The present invention relates to a kind of fleshy duck fodder, particularly a kind of feed for the production of PUFA, EPA and the functional duck that DHA content is high and n-6PUFA/n-3PUFA is low.
Background technology
Along with the raising of people's living standard, in people's diet, the ratio of meat continues to increase, and has therefrom obtained a large amount of fat.The aliphatic acid that forms animal tallow can be divided into saturated fatty acid and unrighted acid substantially by its saturation degree and trophic function, and unrighted acid can be divided into again monounsaturated fatty acids and polyunsaturated fatty acid two classes according to its undersaturated degree.Modern food Nutritional studies shows, content of polyunsaturated fatty acid in diet and the health of human body have substantial connection, the effect of n-3 polyunsaturated fatty acid is wherein particularly outstanding, improve physiological function that the intake of n-3 polyunsaturated fatty acid in diet contributes to keep cell, reduce cholesterol level in blood fat and blood, reduce blood viscosity, improve the activity of brain cell, thereby reduce the incidence of disease of cardiovascular and cerebrovascular disease.Particularly, the eicosapentaenoic acid (EPA) in n-3 polyunsaturated fatty acid and DHA (DHA) have important physiological action to human body.EPA to promote saturated fatty acid in body metabolism, prevent that fat has good function at deposition, preventing hypertension and the cardiovascular and cerebrovascular disease etc. of vascular wall.DHA to child's cranial nerve grow, baby's visual development, children ' s intelligence development etc. have vital effect, and there is antiallergy, strengthen the effect of immunity.But in conventional meat product, the ratio of polyunsaturated fatty acid is conventionally lower, and polyunsaturated fatty acid is main mainly with n-6 polyunsaturated fatty acid, the ratio of n-3/n-6 aliphatic acid is very low, by conventional meat diet, is difficult to increase the intake of n-3 polyunsaturated fatty acid.
Duck is one of meat important in people's meals source, has the features such as rich in protein, moderate fat content, Fat Distribution be even, and various because of its eating method, is deeply subject to liking of broad masses of the people.But aliphatic acid is mainly comprised of saturated fatty acid in the conventional duck of producing, polyunsaturated fatty acid ratio is low, and take n-6 polyunsaturated fatty acid as main, the ratio of n-6/n-3 is higher, contains hardly the functional fatty acids such as EPA and DHA.

Result is as shown in table 3, shows that in the chest muscle of 0.5% daily ration group, 0.75% daily ration group, 1.0% daily ration group, 1.25% daily ration group and 1.5% daily ration group, PUFA content, n-3PUFA content, n-3PUFA are all significantly higher than and contrast daily ration group with quality ratio, DHA, the EPA of n-6PUFA; In the chest muscle of 0.5% daily ration group, 0.75% daily ration group, 1.0% daily ration group, 1.25% daily ration group and 1.5% daily ration group, n-6PUFA content is lower than contrast daily ration group.
In table 3, PUFA, n-3PUFA, n-6PUFA, EPA and DHA content all refer to the quality percentage composition that accounts for TFA, and unit is %.
Table 3, each daily ration group duck polyunsaturated fatty acid account for the percentage composition (%) of TFA
