Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with examples, but the embodiments of the present invention are not limited thereto.

[0020] (1) Experimental grouping and breeding of grouper

[0021] The experimental grouper (Epinephelus coioides) with an initial mass of 64.69±8.65g, a total of 150 fish, was randomly divided into:

[0022] Control group (feed: basal feed);

[0023] Emulsified fish oil group (feed production: base feed wrapped with 2% emulsified fish oil);

[0024] Composite additive I group of the present invention (feed making: Composite bacteria take 20% of photosynthetic bacteria bacterium liquid, 2% of Bacillus pumilus bacterium powder and 78% of Lactobacillus acidophilus bacterium liquid according to the mass percentage combination, first Bacillus pumilus bacterium powder Mix it into the Lactobacillus acidophilus liquid, then mix it with the photosynthetic bacteria liquid to make the grouper feed additive, then mix...

Abstract

The invention discloses an epinephelus coioides feed additive and an application method thereof. The epinephelus coioides feed additive is composed of a photosynthetic bacteria liquid, a bacillus pumilus powder and a lactobacillus acidophilus liquid. The bacillus pumilus powder is firstly mixed with the lactobacillus acidophilus liquid, and then the mixed bacteria is mixed with the photosynthetic bacteria liquid. The mass percentage content scope of the three compositions comprise that the photosynthetic bacteria liquid accounts for 18-22%, the bacillus pumilus powder accounts for 1-3%, and the lactobacillus acidophilus liquid accounts for 75-81%. Based on 1 Kg of base feed, 10 g-50 g of the additive is added, and the additive is uniformly mixed with the base feed, and then the mixture is wrapped by emulsified fish oil. The epinephelus coioides feed additive is suitable for healthy culture of epinephelus coioides, is capable of obviously improving the activity of SOD, AKP and lysozyme in fish body, thereby effectively promoting growth of epinephelus coioides.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a grouper feed additive and a method for using the grouper feed additive. Background technique [0002] The oblique-banded grouper (Epinephelus coioides) belongs to the genus Grouper of the family Anguidae, and is a rare marine economic fish with high edible value and health value; The fish farming industry has developed rapidly, and the grouper has become one of the important cultured species. [0003] In the process of artificial breeding of oblique grouper, it is very important to prevent and manage diseases caused by bacteria, viruses, parasites, etc., especially for cage farms in high-density or highly polluted sea areas. The increased sensitivity of pathogens makes it easier to cause the occurrence and prevalence of diseases. Fishermen often rely on antibiotics to prevent grouper diseases, but the abuse of antibiotics has led to serious food safety problems. Therefo...
