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 of nutrients. incomplete absorption
Therefore, cellulose is difficult to be digested and absorbed in the chicken body, which affects the absorption and transformation of other nutrients in the feed, thereby reducing the absorption efficiency of nutrient-enhanced feed, affecting the use effect of the enhanced feed, and causing waste of feed

Embodiment 1

[0020] (1) Preparation of nutrition enhancer:

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

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

[0023] a. prepare expansion medium 1000L, concrete proportioning is (by weight fraction): corncob powder 10%, yeast extract powder 1%, urea 1%, sodium sulfide 0.1%, potassium dihydrogen phosphate 0.7%, balance for water.

[0024] b. Inoculate 10 L of active Clostridium thermocellum bacteria liquid into the expansion culture medium, and culture it for 15 days under the conditions of 60° C. and an oxygen concentration of less...

Embodiment 2

[0031] Embodiment 2: Different from Embodiment 1,

Abstract

The present invention provides a nutritional enhancer for producing DHA-ARA eggs suitable for infants, and provides the preparation of nutritionally enhanced chicken feed by using the nutritional enhancer and the production of DHA-ARA suitable for infants by using the nutritionally enhanced chicken feed The egg method. The nutrition enhancer is composed of the following components in parts by weight: 10-24 parts by weight of DHA microalgae dry powder, 28-66 parts by weight of ARA microalgae dry powder and 10-50 parts by weight of Clostridium thermocellum dry powder. The nutritional fortifier of the present invention not only solves the problem of not being able to enrich DHA and ARA in eggs at the same time, but also fills the gap in the prior art, and is of great significance to the development of the chicken industry; moreover, the ratio of DHA:ARA reaches the highest level. The optimal ratio of 1:1.5-1:2 realizes the convenient and effective supplementation of DHA and ARA needed for the neurological and visual development of infants and young children, which 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...
