Problems solved by technology

However, only using oil crops such as perilla and flax as feed additives has limited production feasibility. The reason is that eggs are enriched with more n-3 series of unsaturated fatty acids, which greatly weakens their antioxidant properties, resulting in Eggs are perishable and difficult to store

Abstract

The invention discloses a feed additive for producing eggs rich in n-3 series polyunsaturated fatty acid composition. The feed additive adopts an optimized proportion combination by adopting a principle of various plant source function complementation, is added into formula feeds for layer chickens with a ratio of 16 percent, and is used for producing health-care eggs with low cost, safe quality, n-3 series polyunsaturated fatty acid composition enrichment, favorable antioxidant properties, storage stability and easy popularization and application. Compared with ordinary chicken feeds, the feed additive formula enables the n-3PUFA content of a produced egg to be enhanced by 4.01 times to 4.72 times, the level of lipid peroxide (MDA) to be lowered by 20.8 percent to 27.5 percent, and the color of a egg yolk is deepened by 2.1 to 2.4 unit levels (a standard solor fan) when being used for feeding layer chickens. In addition, because added plant resources fulfill has certain efficacy of disease resistance, the feed additive has remarkable effect of nutritional immunity, and the incidence of non-viral diseases of the layer chicken is obviously lowered in a feeding process.

Description

technical field [0001] The invention belongs to the animal husbandry technology in the field of agriculture, and relates to a feed additive utilizing various plant resources in optimized ratios, in particular to a feed additive for producing health-care eggs enriched in n-3 series polyunsaturated fatty acids. Background technique [0002] Eggs are rich in nutrients and are currently recognized as a nutritionally balanced food that best matches the nutritional needs of the human body. Scholars at home and abroad add some ingredients needed for human health care to the feed, and have developed ingredients that reduce eggs that are harmful to human health, such as low-cholesterol health eggs; or enrich ingredients that are beneficial to human health, high vitamin enrichment Healthy eggs etc. [0003] Nutritionists believe that polyunsaturated fatty acids (PUFA) have special physiological functions on the human body. There are mainly n-3 and n-6 ​​series of PUFA in the diet. ...
