Chicken feed additive for increasing the DHA content of eggs

Abstract

The invention provides a chicken feed additive for increasing the DHA content of eggs, characterized in that, the additive is prepared by fish oil, algae powder, flax seed, each of 27.5-60%, 22-24.5% and 45.5-48.5% by weight. The feed additive to feed chicken is prepared by mixing the fish oil, algae powder, flax seed with the weight ratios above well. While using, the prepared additive is added in the normal feeds, and the adding amount thereof is 4-8% of the total weight of the normal feeds, namely, 40-80kg added in the normal feeds per ton, most suitably, 60kg. The feed additive of proper amount added in the normal feeds to feed the chicken is capable of increasing the DHA content in the eggs by 5-6 times, and is high in nutrition, suitable for health of consumers, low cost and easy operation.

Description

technical field [0001] The invention relates to a poultry feed additive, in particular to a chicken feed additive for increasing the DHA (brain gold) content of eggs. Background technique [0002] The so-called "brain gold" in this study is a fashionable term for the unsaturated fatty acid docosahexaenoic acid, and its English abbreviation is DHA. The first to reveal the mystery of DHA was Professor Croft of the British Institute of Brain Nutrition and Professor Oyu Zhanmei, a famous Japanese nutritionist. Their research shows that: DHA is one of the important substances for brain development and growth. There are more than 14 billion neurons in the human brain, and DHA exists in large quantities in brain cells and cell synapses. Necessary substances for development. Deficiency can cause a range of symptoms, including stunted growth, abnormal scaling of the skin, infertility, and intellectual disability. [0003] It is known from the research results that besides water, ...

Problems solved by technology

[0004] At present, concentrated DHA oil products have been launched in the international market, but DHA is a higher polyene fatty acid with high biological activity, and it is also prone to oxidative deterioration

In order to prevent its oxidation, researchers have thought of many methods, such as adding antioxidants, wrapping it in soft capsules, making it into "powdered" products with complex membrane materials such as cyclodextrin or zein, etc., but Its effect is not ideal, and increase the production cost
