Technical Field

The invention relates to the technical field of functional feed, in particular to a chicken feed rich in Omega-3 and an application method thereof.

Background

Omega-3 is a polyunsaturated fatty acid commonly found in deep-sea fishes and some plants, is one of the most important components in the cell structure of the human body, and is also an essential substance for normal operation of cell membranes, so that the Omega-3 is also called as an essential fatty acid, has multiple physiological effects of promoting cardiovascular health, eliminating migraine, preventing diabetes and the like, and is very beneficial to the health of the human body. Since Omega-3 cannot be stored in the human body, the human body needs to take a certain amount of Omega-3 every day to meet the needs of physical health. Common sources of Omega-3 mainly comprise deep sea fish oil, flaxseed, chia seed, seaweed and the like.

At present, people mostly eat health care products or medicines rich in Omega-3 to supplement Omega-3, and related medicines or purified products rich in Omega-3 sold in the market have high price and common taste, the quality of the products is uneven, some side effects are even brought, and for example, fish oil contains toxic substances such as heavy metals and a large amount of cholesterol, which are all unfavorable for human health. Therefore, the Omega-3 needed by the body every day is supplemented by eating the food rich in Omega-3, the method is simple and easy to implement, has moderate cost and no side effect, and the product has better mouthfeel and better quality and is more acceptable to consumers. Therefore, the search for food rich in Omega-3 to replace the traditional Omega-3 supplement medicines and health care products becomes a research hotspot in the field of current functional food.

The egg is the most commonly eaten protein food by people, and not only is rich in nutrition, but also has better taste. The amount of Omega-3 that can be provided in plain eggs is limited. In recent years, a plurality of eggs rich in Omega-3 are produced by laying hens by adding linseed to chicken feed. However, due to the existence of cyanide toxin in flaxseed, the production performance of laying hens is gradually reduced after the laying hens eat the flaxseed for a long time, irreversible damage is caused to the intestinal system and internal organs, and the health and production benefits of chicken flocks are seriously affected. Therefore, the development of a production technology which is rich in Omega-3 and does not influence the health of chicken flocks becomes a research hotspot in the field of current food development.

the content of vitamin E, vitamin C and vitamin B6 in the premix is more than 5 times of that of the common premix.

The invention also provides a method for producing eggs rich in Omega-3 by using the chicken feed, and laying hens can freely eat the feed rich in Omega-3 and can produce eggs rich in Omega-3 after eating for 3-4 weeks.

The laying hens in the laying period are preferably laying hens with the laying rate of more than 90%; the free feeding is not limited in feeding amount, and the chicken feed is supplemented in time.

The technical solutions provided by the present invention are described in detail below with reference to examples, but they should not be construed as limiting the scope of the present invention.

Example 1

10kg of detoxified puffed flaxseed, 57kg of corn, 20kg of bean cake, 5kg of bran, 5kg of bone meal, 3kg of shell powder and 2kg of premix are mixed uniformly to prepare the chicken feed. The weight ratio of the calcium bicarbonate, the compound vitamin, the compound trace element and the compound amino acid in the premix is 15: 0.5: 25: 7. feeding laying hens with laying rate of 90% with the chicken feed, allowing the laying hens to feed freely without limiting feed intake of the laying hens, supplementing the chicken feed in time, and continuously feeding for 4 weeks to produce eggs rich in Omega-3.

Comparative example 1

Flaxseed was normal flaxseed and premix was normal premix, and the other conditions were the same as in example 1.

The chicken feed of example 1 had ALA, DHA and Omega-3 contents of 518, 236 and 754, respectively. The chicken feed of comparative document 1 had ALA, DHA and Omega-3 contents of 354, 166 and 520, respectively. The laying performance of the laying hens in the laying middle stage was tested, and the laying rate of example 1 was 88%, and that of comparative document 1 was 76%.

Example 2

6kg of detoxified puffed flaxseed, 42kg of corn, 12kg of bean cake, 9kg of bran, 8kg of bone meal, 5kg of shell powder and 5kg of premix are mixed uniformly to prepare the chicken feed. The weight ratio of calcium bicarbonate, compound vitamin, compound microelement and compound amino acid in the premix is 30: 1.0: 20: 4. feeding laying hens with laying rate of 90% with the chicken feed, allowing the laying hens to feed freely without limiting feed intake of the laying hens, supplementing the chicken feed in time, and continuously feeding for 3.5 weeks to produce eggs rich in Omega-3.

Comparative example 2

Flaxseed was normal flaxseed and premix was normal premix, and the other conditions were the same as in example 2.

The chicken feed of example 2 had ALA, DHA and Omega-3 contents of 230, 160 and 390, respectively. The chicken feed of comparative document 2 had ALA, DHA and Omega-3 contents of 220, 110 and 230, respectively. The laying performance of the laying hens in the laying middle stage is tested, and the laying rate of example 2 is 90%, and the laying rate of comparative document 2 is 83%.

Example 3

8kg of detoxified puffed flaxseed, 50kg of corn, 15kg of bean cake, 8kg of bran, 6kg of bone meal, 4kg of shell powder and 4kg of premix are mixed uniformly to prepare the chicken feed. The weight ratio of the calcium bicarbonate, the compound vitamin, the compound trace element and the compound amino acid in the premix is 20: 0.7: 23: 6. feeding laying hens with laying rate of 90% with the chicken feed, allowing the laying hens to feed freely without limiting feed intake of the laying hens, supplementing the chicken feed in time, and continuously feeding for 3 weeks to produce eggs rich in Omega-3.

Comparative example 3

Flaxseed was normal flaxseed and premix was normal premix, and the other conditions were the same as in example 3.

The chicken feed of example 3 had ALA, DHA and Omega-3 contents of 450, 210 and 650, respectively. The chicken feed of comparative document 3 had ALA, DHA and Omega-3 contents of 300, 138 and 420, respectively. The laying performance of the laying hens in the laying middle stage was tested, and the laying rate of example 3 was 89%, and that of comparative document 3 was 79%.

As can be seen from examples 1 to 3 and comparative examples 1 to 3, the eggs of the present invention are rich in ALA, DHA and Omega-3. Compared with the common flaxseed and premix added in the chicken feed, the feed has higher Omega-3 fatty acid enrichment efficiency. The method for producing the eggs rich in Omega-3 by using the chicken feed provided by the invention does not basically reduce the production performance of the laying hens.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
