Laying hen feed additive rich in omega-3 fatty acid and using method of feed additive

Abstract

The invention discloses a laying hen feed additive rich in omega-3 fatty acid and a using method of the feed additive. The laying hen feed additive comprises the following components in parts by weight: 9 to 10 parts of pepper seed mixed powder, 0.5 to 0.8 part of solid fish oil fatty acid calcium, 0.01 to 0.02 part of 98 percent vitamin C, and 0.004 to 0.006 part of 50 percent vitamin E, wherein the pepper seed mixed powder comprises 1 / 3 of pepper seed powder and 2 / 3 of corn powder. When the laying hen feed additive disclosed by the invention is used, a conventional energy feed according to a laying hen feed formula is replaced by an equal amount of the feed additive which accounts for 9.5 to 11 percent of the weight of feed, so that the content of protein in the feed is guaranteed; cheap polyunsaturated fatty acid raw materials (the fish oil fatty acid calcium and pepper seeds) are filtered by laying hens and are accumulated in egg yolk, so that the eggs which are rich in omega-3 fatty acid and are unlikely to cause rancidity are produced.

Description

technical field [0001] The invention relates to the field of poultry feed, in particular to a layer hen feed additive rich in omega-3 fatty acids and a use method thereof. Background technique [0002] my country is the world's largest producer of eggs, accounting for more than 42% of the world's output, with a per capita egg production of more than 17 kilograms, which has met consumer demand in terms of quantity. And along with the raising of people's living standard, the consumer has put forward higher requirement to the quality of egg product. In the case of an oversupply of ordinary eggs, the products of the main road "collision in a narrow road", the price is low, and there is a situation of increasing production but not increasing income, while eggs enriched with nutrients (enriched in selenium, omega-3 fatty acids, etc.) The price of eggs is doubled, which is popular among consumers and has become a new consumption growth point for eggs. Studies have shown that inta...

Problems solved by technology

[0003] The omega-3 fatty acid eggs on the market now mostly adopt the method of adding oil containing omega-3 fatty acid to the feed. The oil used in this method needs to be refined, thereby increasing production costs, and contains high unsaturated fatty acids, which are easy to oxidize Rancidity, leading to problems such as egg protein thinning and odor
