Embodiment Construction

[0027] In order to make the technical means, creative features, goals and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0028] Table 1 formula (by weight parts)

[0029] Proportion

[0030] Formulation of the present invention is shown in Table 1.

[0031] In 2009, in Zhejiang Aohua Feed and Feed Co., Ltd. (Zhejiang, Jiaxing) indoor aquaculture water system, the inventor completed the experiment on the survival rate and growth of adult shrimp in Penaeus vannamei (Penaeus vannamei). Good experimental results were obtained. The specific experiment is as follows:

[0032] 1. Experimental design

[0033] Based on Penaeus vannamei No. 2 feed (produced by Zhejiang Aohua, particle diameter 1.6mm) as the basic feed formula (crude protein ≥ 41%), 0‰, 1‰, 2‰, 4‰ and 8‰ of food-inducing and stimulating substances were added respectively. Long dose (choose formula 2). ...

Abstract

The invention discloses a feeding attraction and growth promoting agent for medium-growing shrimps, the formula of which is as follows in parts by weight: 40-70 parts of taurine, 10-30 parts of betaine hydrochloride and 15-35 parts of composite yeast powder. The active ingredients of taurine and betaine hydrochloride respectively account for 95-99% and 98-100%. The composite yeast powder is formed by spray drying the broken wall of active dry yeast, and the main functional components of the composite yeast powder are respectively yeast nucleotide, yeast cellwall polysaccharide and small peptide. The invention further discloses a production method of the feeding attraction and growth promoting agent for the medium-growing shrimps, which comprises the following steps: weighing raw materialsin parts by weight: 40-70 parts of taurine, 10-30 parts of betaine hydrochloride and 15-35 parts of composite yeast powder, removing impurities and ultra-finely grinding; mixing; screening by a sieveof 30 meshes; and packaging.

Description

technical field [0001] The invention relates to a growth-promoting agent for shrimp, in particular to a food-inducing and growth-promoting agent for medium-grown shrimp and a production method thereof. Background technique [0002] With the increasing development of the aquaculture industry today, natural bait can no longer meet the production needs. A large number of artificial compound feeds are used, additives are added to the compound feed, and the palatability of the feed and the feeding speed of farmed animals are improved by adding attractants. Reducing the dissolution and loss of feed in water and increasing the proportion of unconventional feed raw materials have become one of the main directions of compound feed research. However, the selection of food attractants should not only consider factors such as the physiological characteristics of farmed animals, feeding inhibitors in feed ingredients, but also their own functional characteristics, cost performance, sourc...
