Embodiment 1

[0037] 1. A fish feed that improves breeding efficiency, comprising the following components in parts by weight: 35 parts of fish meal, 16 parts of soybean meal, 12 parts of starch, 1 part of vegetable oil, 0.8 part of calcium dihydrogen phosphate, 1 part of mineral matter, and 0.8 part of choline , 80 parts of water and 3 parts of konjac glucomannan.

[0038] Wherein, the preparation method of konjac glucomannan is as follows:

[0039] S1. Weigh 100g konjac flour and dissolve it in 25ml 50% ethanol solution configured in advance and stir evenly to form mixture A;

[0040] S2. Seal the container containing the mixture A with a plastic wrap, then stir the mixture A for 35 minutes with a magnetic stirrer, and add 30% H 2 o 2 7ml, 7ml, 3.5ml, add 30% H 2 o 2 It is necessary to uncover the plastic wrap when adding, cover it after adding, and add a total of 17.5ml30%H 2 o 2 , to obtain mixture B;

[0041] S3. Put the mixture B together with the container into a constant temp...

Embodiment 2

[0059] This embodiment refers to Example 1. The difference is that the fish feed includes the following components in parts by weight: 45 parts of fish meal, 24 parts of soybean meal, 10 parts of starch, 4 parts of rapeseed oil, 1.5 parts of calcium dihydrogen phosphate, mineral 2 parts, 1.2 parts of choline, 100 parts of water and 1 part of konjac glucomannan.

Embodiment 3

[0061] This embodiment refers to Example 1, and the difference is that it includes the following components in parts by weight: 40 parts of fish meal, 22 parts of soybean meal, 10 parts of starch, 2 parts of rapeseed oil, 1.0 parts of calcium dihydrogen phosphate, 2 parts of minerals, gallbladder 1.2 parts of alkali, 100 parts of water and 3 parts of konjac glucomannan.

Abstract

The invention relates to fish feed with a function of improving the aquaculture efficiency, a method for preparing the fish feed and a method for feeding schizothorax prenati with the fish feed. The fish feed with the function of improving the aquaculture efficiency comprises, by weight, 35-45 parts of fish meal, 16-24 parts of bean pulp, 10-12 parts of starch, 1-4 parts of rapeseed oil, 0.8-1.5 parts of calcium dihydrogen phosphate, 1-2 parts of minerals, 0.8-1.2 parts of choline, 80-100 parts of water and 1-3 parts of konjac glucomannan. The fish feed and the methods have the advantages thatthe konjac glucomannan is added into the fish feed, the immune performance of the schizothorax prenati can be obviously enhanced after the schizothorax prenati is fed with the fish feed, the survivalrate can be obviously increased, the economic benefit can be effectively increased, and the aquaculture cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of biological feed, in particular to a fish feed for improving breeding efficiency, a preparation method and a feeding method thereof. Background technique [0002] Schizothorax has low immunity and is more sensitive to external stimuli. In recent years, due to environmental pollution and other reasons, the amount of fish resources has decreased sharply, resulting in economic damage to fishermen and a sharp rise in fish market prices. Therefore, there is an urgent need to develop a feed that can improve the immune performance of schizothoracids. [0003] Konjac glucomannan, also known as konjac polysaccharide, is composed of D~mannose and D~glucose in a ratio of 1.6:1 connected by β-1,4 glycosidic bonds. It is a natural polymer heteropolysaccharide with the highest viscosity known. Konjac glucomannan is an immunomodulator, which has the effect of improving immunity, mainly through the following two ways: on...
