Problems solved by technology

[0009] There are deficiencies in the current omega-3 fatty acid fortified egg nutrition research: (1) fish oil resources are limited, and are easy to oxidize, so it is not easy to store; when fish oil is added to the diet, the content of fatty acid peroxides in egg yolk is high, which may easily cause fish to appear in the food; Fishy smell, and prone to chronic diseases
(2) Flaxseed mainly contains linolenic acid, which is relatively stable to oxidation. This acid needs to be metabolized into DHA in the body, but this process

Embodiment 1

[0038] The feed for laying hens rich in polyunsaturated fatty acids of the present invention consists of the following components in parts by weight: 61.7 parts of corn, 24 parts of medium protein soybean meal, 1 part of puffed soybean, 8.5 parts of stone powder, 0.7 part of calcium hydrogen phosphate, 3 parts of fermented grass cake, 1 part of 1% laying hen premix.

[0039] The preparation method of the fermented grass cake is as follows: store the evening primrose cake in a special container, add 3% saccharification liquid at a ratio of 4:6, adjust the sugar and water content of the raw materials, and ensure the solubility required for the fermentation of lactic acid bacteria The amount of sugar, the pH value is adjusted to 6.0, the temperature is controlled between 30°C, and then the lactic acid live bacteria agent is added quantitatively to ensure that the lactic acid bacteria quickly become the dominant bacteria during fermentation, sealed and fermented for 6 days, and fin...

Embodiment 2

[0042] The feed for laying hens rich in polyunsaturated fatty acids of the present invention is composed of the following components in parts by weight: 60.5 parts of corn, 23 parts of medium protein soybean meal, 1 part of puffed soybean, 8.5 parts of stone powder, 1 part of calcium hydrogen phosphate, 5 parts of fermented grass cake, 1 part of 1% laying hen premix.

[0043] The preparation method of the fermented grass cake is as follows: store the evening primrose cake in a special container, add 4% saccharification liquid at a ratio of 4:7, adjust the sugar and water content of the raw materials, and ensure the solubility required for the fermentation of lactic acid bacteria The amount of sugar, the pH value is adjusted to 6.0, the temperature is controlled between 28°C, and then the lactic acid live bacteria agent is added quantitatively to ensure that the lactic acid bacteria quickly become the dominant bacteria during fermentation, sealed and fermented for 7 days, and fi...

Abstract

The invention discloses forage rich in polyunsaturated fatty acid for laying hen, which includes following weight of components: 60-64 parts of corn, 22-25 parts of protein soybean meal, 0.8-2 parts of puffing soybean, 8-9 parts of stone powder, 0.5-1.0 parts of calcium hydrogen phosphate, 2-6 parts of fermentation straw cake, and 0.8-1.2 parts of 1% laying hen premix. The invention fully satisfies nutrition needs of laying hen egg product period, thereby guaranteeing that the laying hen produces egg under health and nutrition state. By using evening primrose cake as omega-3 fatty acid source and fermenting the evening primrose cake through malolactic bacteria fermentation technology, the invention effectively removes nutrition restriction factor in raw material, increases safety and amount of the raw material, and simultaneously provides source of conjugated linoleic acid for functional egg production by conversing free linoleic acid into the conjugated linoleic acid through malolactic bacteria. Compared with fish oil and alga product, the raw material-evening primrose cake of the present invention has low investment cost, has abundant resource, is not easily oxidized and deteriorated, avoids change of egg flavor, and is convenient for usage with large quantity in production.

Description

technical field [0001] The invention relates to a feed for laying hens, in particular to a feed for laying hens rich in polyunsaturated fatty acids. Background technique [0002] Eggs occupy an important position in people's diet structure, and are hailed as the "treasure house" of human nutrition by nutritionists. The egg yolk accounts for about 50% of the egg, and 60% to 65% of the egg yolk is lipids. Fatty acids, especially unsaturated fatty acids, play an important role in the prevention of cardiovascular diseases, etc., and people pay more and more attention to them. Since researchers found that food has a certain relationship with heart disease in 1980, people have paid more and more attention to foods containing fatty acids and heart disease. Cholesterol products, dietary modification to increase the PUFA content of eggs is a consistent and stable route to increase the PUFA content of human food. [0003] Polyunsaturated fatty acid (PUFA) refers to a straight-chain f...
