Or the nutritional functional bag comprises the following components in parts by weight: 0-40 parts of grape seeds, 40-90 parts of flaxseeds and 10-60 parts of algae powder, preferably, the algae powder comprises 9-50 parts of DHA algae powder and 1-10 parts of EPA algae powder.
Preferably, the DHA content in the DHA algae powder is more than or equal to 5; the EPA content in the EPA algae powder is more than or equal to 2 percent.
According to another aspect of the present invention, there is provided a feed comprising the nutritional functional packet.
Preferably, the nutritional functional bag is added in an amount of 1-10% based on the total weight of the feed.
According to a further aspect of the present invention there is provided the use of a nutritional functional pack as described above for increasing the content of unsaturated fatty acid components in milk.
The nutritional functional bag provided by the invention can promote the anabolism of omega-3 unsaturated fatty acid and main components thereof in milk and reduce the influence on the health and production performance of the cow body through the combination of the vegetable oil or the vegetable oil seeds and the algae powder, thereby increasing the content of the omega-3 unsaturated fatty acid and the main components thereof in the milk.
Detailed Description
Technical features, objects and advantages of the present invention will be more clearly understood and appreciated by those skilled in the art. It should be understood that the following detailed description is merely exemplary, and the technical aspects of the present invention are not limited to the specific embodiments listed below.
The invention provides a nutrition regulation and control method for increasing contents of omega-3 unsaturated fatty acid and main components thereof in milk through a nutrition function package, wherein the nutrition function package comprises the following components: one, two or three of algae powder, vegetable oil seeds and vegetable oil.
The algae powder usable in the present invention may include one or both of DHA algae powder and EPA algae powder. Wherein the DHA algae powder has a fat content of more than 10% of the total fatty acids of the algae powder, the DHA content of more than or equal to 5%, the EPA algae powder has a fat content of more than 10% of the total fatty acids of the algae powder, and the EPA content of more than or equal to 2%.
The algae powder can be in the form of powder formed by coating and processing algae.
The vegetable oil can be one or two of linseed oil and grape seed oil, and is preferably linseed oil or grape seed oil. The vegetable oil can be microcapsule powder formed by coating, and the content of fat is more than 55% of the raw material.
The vegetable oil seed can be one or more of flaxseed, hemp seed and grape seed, and preferably two of the flaxseed, hemp seed and grape seed are compounded. The vegetable oil seed can be processed by parching and baking, or processed by pulverizing to obtain powder, or processed by coating to obtain microcapsule powder.
In order to improve the anti-oxidative stress capability of the dairy cows, the nutritional functional bag can also comprise one or two of vitamin E and organic selenium. The addition amount of the compounds in the daily ration of the dairy cow can be 1 g-5 g/day. The organic selenium can be organic selenium of the type commonly used in feed, such as selenium yeast.
According to a specific embodiment of the present invention, the nutritional functional bag comprises the following components in parts by weight: 15-75 parts of grape seed oil, 22-80 parts of linseed oil and 5-50 parts of algae powder, preferably 5-50 parts of DHA algae powder.
