Embodiment Construction

[0013] The following examples will further illustrate the present invention.

[0014] 1. Single factor experiment

[0015] 1 experimental group

[0016] 1600 tilapias of about 50g were randomly divided into 16 groups, and they were reared in a water body of 8.75m×8.13m, 0.5-0.8m. Set up 4 groups of tests simultaneously, be respectively control group, low dose (0.5g / kg) group, middle dose (1g / kg) group, high dose (2g / kg) group, each group of tests is set up 3 parallel.

[0017] 2 Experimental methods

[0018] The test site is an intelligent fish breeding system in the National (Fuqing) Modern Agriculture Demonstration Park, which was jointly established by the police and initiated by the Fujian Academy of Agricultural Sciences. Use the fish premixed feed of Fujian Tianma Technology Group Co., Ltd. to prepare the bait according to the standard, and then add the seaweed oligosaccharide in the formula amount in the experimental group to the bait.

Abstract

The invention discloses an alga oligosaccharide fish feed additive and relates to an alga oligosaccharide. Aiming at solving the problems of the prior art, the invention provides the alga oligosaccharide fish feed additive. The alga oligosaccharide fish feed additive improves a feed utilization rate, promotes growth, improves disease resistance, reduces a cost and improves fish quality. The alga oligosaccharide of the alga oligosaccharide fish feed additive is gracilaria lemaneiformis agar oligosaccharide and is a mixture which comprises tetrasccharide to octasaccharide and is obtained through co-culture of a Flammeovirga Pacifica H2 strain and gracilaria lemaneiformis so that gracilaria lemaneiformis is directly degraded through an enzyme produced through microorganism. The Flammeovirga Pacifica H2 has a preservation number of CCTCC NO: M2012229.

Description

technical field [0001] The invention relates to a seaweed oligosaccharide, in particular to an application of the seaweed oligosaccharide from asparagus in preparing fish feed additives and a method thereof. Background technique [0002] Feed additives refer to small or trace amounts of nutritive or non-nutritive substances added during feed production, processing, and use. They are used in small amounts in feed but have significant effects. Feed additives are inevitable raw materials used in the modern feed industry. They have obvious effects on strengthening the nutritional value of basic feed, improving animal production performance, ensuring animal health, saving feed cost, and improving animal product quality. Therefore, it is necessary to improve the utilization rate of fish feed through the form of feed additives, to reduce the utilization of protein sources such as fishmeal in feed, to develop and expand feed resources, so as to improve the survival rate, disease res...
