Anti-stress enhancer for macrobrachium rosenbergii and application thereof

Abstract

The invention discloses an anti-stress enhancer for macrobrachium rosenbergii and application thereof. The anti-stress enhancer is characterized by being prepared from the following components in parts by weight: 5-10 parts of yeast nucleotide, 5-10 parts of astaxanthin, 5-10 parts of chitosan, 15-20 parts of fructooligosaccharide, 15-20 parts of mannan oligosaccharide, 10-15 parts of chitosan-zinc, 5-10 parts of vitamin C, 10-15 parts of saccharicterpenin, 5-10 parts of uncaria rhynchophylla and 5-10 parts of rhizoma corydalis. 0.03-0.05 percent by mass of the anti-stress enhancer is added in formula feed. The anti-stress enhancer has the advantages that only 0.03-0.05 percent by mass of the anti-stress enhancer is added into formula feed, the survival rate of macrobrachium rosenbergii can be increased by 10.83-30.13 percent, the weight gain rate can be increased by 168.32-357.89 percent, and the survival rate is increased by about 30 percent under an environmental stress condition.

Description

technical field [0001] The invention relates to a feed additive for Macrobrachium rosenbergii, in particular to an anti-stress enhancer for Macrobrachium rosenbergii and its application. Background technique [0002] Macrobrachium rosenbergii belongs to Arthropada, Crustacea, Decapoda, Palaemonidae, Macrobrachium, also known as Malaysian prawn. It has the advantages of wide food, good meat quality and short breeding cycle, etc. It is known as the "freshwater shrimp king" and is a relatively large tropical economic shrimp. The second leg of Macrobrachium rosenbergii is pincer-shaped and thicker than other legs. It is called a claw foot, especially the male claw leg is particularly developed, which is mainly used for attack and defense behaviors. Under intensive high-density breeding conditions, its attack behavior More obvious. In addition, rapid changes in environmental conditions such as water temperature changes (low temperature, high temperature), transportation, shock, ...
