Artificial compound feed for improving vibrio resistance of penaeus vannamei boone as well as preparation method and application of artificial compound feed

Abstract

The invention discloses an artificial compound feed for improving vibrio resistance of penaeus vannamei boone as well as a preparation method and an application of the artificial compound feed. The artificial compound feed comprises the following components: fish meal, blood cell powder, squid paste, shrimp shell powder, soybean meal, peanut kernel cakes, cottonseed meal, flour, phospholipid oil,a multi-vitamin multi-mineral premix, monocalcium phosphate, an antioxidant, a mildew preventive, choline chloride and chitosan quaternary ammonium salt. The preparation method comprises the followingsteps: weighing the components, crushing the components except the phospholipid oil, sieving with a 80-100-mesh sieve to obtain a solid crushed material, uniformly mixing the solid crushed material with the phospholipid oil, granulating, cutting, cooling, and sieving to remove powder, thereby obtaining the artificial compound feed capable of improving the vibrio resistance of penaeus vannamei boone. According to the invention, the loss caused by high disease incidence of the penaeus vannamei boone due to vibrio infection can be reduced, and the yield and success rate of the penaeus vannamei boone culture industry are improved.

Description

technical field [0001] The invention relates to the technical field of aquatic feed, in particular to an artificial compound feed for improving the anti-vibrio ability of Penaeus vannamei, a preparation method and an application thereof. Background technique [0002] During the breeding process of Penaeus vannamei, the phenomenon of draining ponds caused by Vibrio infection occurs frequently, which affects the harvest of many farmers. Take the shrimp body or shrimp pond water for culture medium detection, and found that the yellow colonies are Vibrio harveyi and Vibrio alginolyticus, and the blue-green ones are Vibrio parahaemolyticus. In the research on the diseases of prawns, it was found that the main pathogenic bacteria causing bacteremia of prawn larvae, red body disease and white spot disease of prawns were Vibrio alginolyticus and Vibrio parahaemolyticus. Most of the pathogenic Vibrio have a strong ability to invade, adapt to the host's internal environment and grow ...

AI Technical Summary

Problems solved by technology

In the breeding process, if encountering eutrophic water body, rainy weather, water temperature, salinity, transparency, PH and dissolved oxygen mutations caused by alternating cold and hot, the Vibrio in the shrimp body and the water body will reproduce and replicate in large numbers, thus Accelerate the spread and prevalence of Vibrio, posing a serious threat to farming

[0003] At present, due to the deterioration of the breeding environment, the degradation of Penaeus vannamei germplasm resources, the increased competition pressure of feed companies and the use of a large number of alternative raw materials, etc., the diseases of Penaeus vannamei are frequent during the breeding process, so it is necessary to develop a method that can improve Artificial Compound Feed for Anti-Vibrio Ability of Penaeus vannamei
