Problems solved by technology

The digestive tract of chickens not only has no corresponding enzymes, but also has a short digestive tract and a small volume, and the feed passes through the digestive tract at a faster speed. Generally, the feed is excreted 4 hours after ingestion, and the indigestible part is excreted within 24 hours, which is harmful to the digestion

Example Embodiment

[0019] Example 1:

[0020] (1) Preparation of nutritional supplements:

[0021] The nutritional fortifier used to produce DHA-ARA eggs suitable for infants and young children, in parts by weight, consists of the following components: 10 parts by weight of DHA dry microalgae powder, 40 parts by weight of ARA microalgae dry powder and 50 parts by weight Clostridium thermocellum dry powder.

[0022] The DHA microalgae dry powder is Schizochytrium dry powder, and the ARA microalgae dry powder is Mortierella dry powder. The dry powder of Clostridium thermocellum is prepared by the following method:

[0023] a. Prepare expansion culture medium 1000L, the specific ratio is (by weight): 10% corn cob powder, 1% yeast extract powder, 1% urea, 0.1% sodium sulfide, 0.7% potassium dihydrogen phosphate, the balance For water.

[0024] b. Inoculate 10L of live Clostridium thermocellum liquid into the expansion culture medium, and cultivate for 15 days under the conditions of 60°C and an oxygen conc...

Abstract

The invention provides a nutrition enhancer for producing DHA-ARA eggs applicable to infants and young children, and provides a method for preparing a nutrition-enhanced chicken feed by adopting the nutrition enhancer and producing the DHA-ARA eggs applicable to infants and young children by adopting the nutrition-enhanced chicken feed. The nutrition enhancer is composed of the following components by weight: 10 to 24 parts by weight of a DHA microalgae dry powder, 28 to 66 parts by weight of an ARA microalgae dry powder and 10 to 50 parts by weight of a Clostridium thermocellum dry powder. The nutrition enhancer provided by the invention solves the problem of incapability of simultaneously enriching DHA and ARA in eggs, fills the gap of the prior art, and has an important significance ondevelopment of chicken industry; meanwhile, the ratio of DHA to ARA reaches an optimal ratio of 1: 1.5 to 1: 2, so the nutrition enhancer provided by the invention realizes convenient and effective supplementation of DHA and ARA required for nerve and visual development of infants and young children, and has important social significance.

Description

technical field [0001] The invention belongs to the field of feed, and mainly relates to a nutrition enhancer used for producing DHA-ARA eggs suitable for infants; the invention also relates to the use of the nutrition enhancer to prepare nutrition-enhanced feed and the use of the nutrition-enhanced feed to obtain DHA -ARA egg method. Background technique [0002] Docosahexaenoic Acid (DHA) is an essential omega-3 polyunsaturated fatty acid that must be supplemented from the diet. DHA is an important structural lipid component of the central nervous system and retina. Its content is as high as 20% in the human cerebral cortex and about 50% in the eye retina. It is an essential nutrient for the development of the nerves and vision of fetuses and infants. The World Health Organization recommends that the supplementary amount of infants and young children is 20mg DHA / Kg / d, and premature infants should be supplemented with 40mg DHA per kilogram of body weight per day. As the m...
