Embodiment 1

[0010] A feed rich in DHA, characterized in that: the feed basic diet is uniformly stirred according to the following weight percentages: 61.6% corn, 28.6% soybean meal, 1.5% calcium hydrogen phosphate, 7.9% stone powder, 0.3% salt, multidimensional 0.1%, lysine 0.1%, and the amount of algae meal containing DHA is 4.9% of the basic diet.

Embodiment 2

[0012] A feed rich in DHA, characterized in that: the feed basic diet is uniformly stirred according to the following weight percentages: 61.4% corn, 28.4% soybean meal, 1.4% calcium hydrogen phosphate, 7.9% stone powder, 0.3% salt, multidimensional 0.3% lysine, 0.3% lysine, and 9.8% of the basal diet with algae meal containing DHA.

Embodiment 3

[0014] A feed rich in DHA, characterized in that: the feed basic diet is uniformly stirred according to the following weight percentages: 61.4% corn, 28.4% soybean meal, 1.5% calcium hydrogen phosphate, 7.9% stone powder, 0.4% salt, multidimensional 0.1%, 0.3% lysine, and 14.7% of the basal diet with algae meal containing DHA.

[0015] Select 180 healthy laying hens with the same age, good health and similar body weight, and randomly divide them into 6 groups, three groups are the test group, and the other three groups are the control group. Wherein the feed of the test group adopts the formulas of the above-mentioned examples 1, 2 and 3, and the algae meal containing DHA of the control group is default. The experimental layer hens were reared in three-layer three-layer cages in a semi-open chicken house, artificially fed, fed twice a day, and had free access to food and water. Other feeding conditions and management systems were the same, and they were reared and managed by s...

Abstract

The present invention provides a feed rich in docosahexaenoic acid (DHA). The feed is formed by uniformly stirring base feed and algal meal containing DHA according to a certain proportion, wherein the base feed comprises corn, soybean meal, dicalcium phosphate, stone powder, salt, multi-vitamin premix and lysine, and the algal meal is formed by subjecting by-products in micro-organism oil production process to drying and grinding. The resources of the feed are wide, the cost is low, the preparation method is easy and convenient to operate, the feed does not contain harmful components, the content of DHA in livestock and poultry products is increased, and the feed is suitable for large-scale production and application.

Description

technical field [0001] The invention belongs to the technical field of livestock and poultry feed preparation, and in particular relates to a feed rich in docosahexaenoic acid. Background technique [0002] Docosahexaenoic acid (DHA) is an omega-3 essential fatty acid, commonly known as "brain gold", which is the main element for the growth and maintenance of human nervous system cells, and an important component of the brain and retina. The content of human cerebral cortex is as high as 20%, and it accounts for about 50% in the retina of the eye. It is very important for the development of intelligence and vision of infants. It also has the functions of protecting the cardiovascular and cerebrovascular system and enhancing immunity. DHA cannot be synthesized by the human body, and can only be supplemented and absorbed from the outside world. Therefore, foods rich in DHA, such as eggs, milk, and meat, have broad market prospects. [0003] Schizochytrium (SL), also known as ...
