Abstract
The invention discloses an anti-stress additive for crayfishes. The additive consists of the following raw materials in parts by weight: 30-45 parts of citric acid, 15-25 parts of vitamin C palmitate,10-25 parts of raw ginger extract, 7-20 parts of yeast cell wall polysaccharide, and 5-15 parts of Hengxing compound trace mineral element "Life support element". The preparation method is as follows: respectively crushing the raw materials, performing uniform mixing according to a certain proportion, and performing drying. The addition mass percentage of the anti-stress additive in the crayfishfeed is 5-10%; According to the invention, under the synergistic effect of the components, the addition of the anti-stress additive in the feed is only 5-10%, the average final weight of the crayfishes is improved by 11-18.6%, and the survival rate is improved by 9.33-34.67%.
Description
technical field [0001] The invention relates to an anti-stress additive for freshwater shrimps, in particular to an anti-stress additive for crayfish and its application. Background technique [0002] Crayfish, the scientific name Procambarus clarkii (Procambarus clarkii), also known as red crayfish, freshwater crayfish, etc., belongs to the class Crustacea, subclass Mollusca, decapod, crayfish family, and the genus Procambarus. Because of its delicious meat, rich nutrition and high protein content, it is very popular among people and has a huge market potential. However, in the process of artificial breeding, there are more and more stress factors, such as water pollution, water temperature changes, fright, malnutrition of bait, invasion of harmful substances, and improper management of fishing, transportation, and feeding, etc. Stress response can not only directly affect the normal growth, development and reproduction of crayfish, but also lead to the decline of immunity...
