Abstract

The invention discloses a diet regulating and controlling method for producing mutton enriched with conjugated linoleic acid. The method adopts concentrate feed, roughage, oil seeds and activated charcoal to form diet for feeding sheep 5-12 month old, wherein the mass ratio of the concentrate feed and the roughage is 4:6-5:5, and the mass of oil seeds is 7%-12% of the sum of the masses of the concentrate feed and the roughage, and the mass of the active carbon is 2%-10% of the mass of the concentrate feed. As sheep are fed through the method, the content of cis-9, trans-11C18:2 conjugated linoleic acid in mutton obtained after slaughtering the sheep is improved above 80% on the average compared with mutton of sheep with the same variety and age which are fed by the common method, conjugated linoleic acid in mutton mainly comes from a generation path in sheep bodies. The method is simple and easy to operate, has lower production cost, and is easy to popularize and apply.

Description

technical field [0001] The invention relates to a dietary regulation method for producing mutton rich in conjugated linoleic acid. Background technique [0002] Conjugated linoleic acid (CLA) refers to a series of mixtures of octadecadienoic isomers containing conjugated double bonds and having different positions and spatial configurations. It is a natural active substance. . The types of conjugated linoleic acid are very rich, and there are at least 24 isomers. Among these isomers, the isomers of conjugated linoleic acid that have physiological and health effects on the human body are mainly: cis-9, trans-11 -Conjugated linoleic acid. The milk and meat products of ruminant livestock such as cattle and sheep are the main sources of human beings to obtain conjugated linoleic acid. [0003] Studies have shown that there are two pathways for the production of conjugated linoleic acid in ruminants. One is the rumen production pathway, that is, some bacteria in the rumen can...
