Poultry feed additive, feed containing the same and application thereof

Abstract

The invention provides a poultry feed additive for increasing the content of polyunsaturated fatty acids (PUFA) in poultry meat and eggs. The poultry feed additive contains an algae component, and one or more of the following: agricultural product processing leftovers, an antioxidant or a microecological preparation, wherein the algae component is algae powder and its derivative product. The invention also provides poultry feed containing the additive, and a method for feeding poultry with the additive or feed to increase the content of PUFA in poultry meat and eggs.

Description

technical field [0001] The present invention provides a feed additive for increasing the content of polyunsaturated fatty acid (PUFA) in poultry meat and poultry eggs, provides feed containing the additive, and uses the additive or feed to feed poultry to improve poultry meat and poultry eggs. method for polyunsaturated fatty acid (PUFA) content. Background technique [0002] Microalgae are aquatic photoautotrophic microorganisms that use light energy to produce CO 2 and H 2 O is used as a substrate to grow cells, synthesize proteins, polyunsaturated fatty acids (PUFA), essential amino acids, etc., rich in essential amino acids, vitamins, pigments, minerals, etc., and has important application value in food, medicine, feed and other fields . [0003] In recent years, with the improvement of social living standards and changes in people's lifestyles, the incidence of cardiovascular and cerebrovascular diseases such as atherosclerosis, coronary heart disease, hypertension, ...

Problems solved by technology

[0009] The purpose of the invention patent application CN200910193736.4 is to provide the source of protein raw materials, without explicitly mentioning its function in application; the invention patent application CN98809331 is to prepare protein peptide feed with algae dregs; Phaffia yeast is mixed and used for eel farming; US patent applications US20090864399 and US2011138682A1 are aimed at the cultivation, harvesting and processing of a Scenedesmus, and its application is only briefly mentioned in the background description without explicitly mentioning its function

The patent CN98809331.6 has the following deficiencies: 1. The patent focuses on the protection of the feeding system, and the key technologies such as feed formula, processing, and storage are not clear; 2. The range of raw materials containing Ω-3 HUFA is too large and vague, and the discussion Plants, animals, and microorganisms containing omega-3 HUFA are covered, but only the raw materials used in the examples are specified to be Schizochytrium sp, and some raw materials that can be converted into DHA precursor substances are also excluded; 3. The raw materials are based on DHA , the results are based on Ω-3HUFA, and there are deviations; 4. The dosage of raw materials used in the test is vague, and only shows the content of DHA in the raw materials; 5. This patent is for the feeding process of broiler chickens, and does not emphasize the laying hens

Moreover, when the patent mentions the part of microbial bacteria (algae), it only emphasizes that it is a raw material containing omega-3 HUFA, and makes a unified introduction from the aspects of use timing and use effect, and does not focus on its use and processing methods, proportioning, attention issues, etc., and argues that while microalgae provide a stable source of naturally entrapped omega-3 HUFAs, they are rather expensive to grow in artificially controlled conditions such as fermenters
