Example Embodiment

[0009] Example one

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

Example Embodiment

[0011] Example two

[0012] A feed rich in DHA, which is characterized in that the basic feed is uniformly mixed in the following weight percentages: corn 61.4%, soybean meal 28.4%, calcium hydrogen phosphate 1.4%, stone powder 7.9%, table salt 0.3%, multivitamin 0.3%, lysine 0.3%, and DHA-containing algal meal is 9.8% of the basic diet.

Example Embodiment

[0013] Example three

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

[0015] A total of 180 healthy laying hens of the same age, good physical condition and similar weight were selected and randomly divided into 6 groups, three groups were experimental groups, and the other three groups were control groups. The feed of the test group adopts the formulas of Examples 1, 2 and 3 above, and the DHA-containing algae meal of the control group defaults. The experimental laying hens were reared in a semi-open hen house with 3 layers of three-dimensional cages, artificially fed, fed twice a day, with free intake and drinking water, other feeding conditions and management systems were the same, ...

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 ...
