Preparation for preventing and treating prawn enterocytozoon hepatopenaei disease as well as preparation method and application thereof

Abstract

The invention discloses a preparation for preventing and treating prawn enterocytozoon hepatopenaei disease as well as a preparation method and application thereof. The preparation is prepared from the following raw materials: rosemary oil, anise oil, talcum powder and auxiliary materials. The preparation comprises following components in percentage by mass: 3.0 to 3.5 percent of rosemary oil, 1.0 to 2.0 percent of anise oil, 15.0 to 18.0 percent of talcum powder and 78.0 to 80.0 percent of auxiliary materials. The talcum powder is feed-grade talcum powder, and the auxiliary material is corn starch. The invention also provides a preparation method and application of the preparation. The preparation is added into a prawn feed for use, which is mixed with the feed and is orally taken for feeding, 2-3g of the preparation is added into per kilogram of the prawn feed, and the preparation is continuously used for 5-7 days. The compound preparation prepared by the invention is safe to target animals, can effectively inhibit the growth of the enterocytozoon hepatopenaei and kill the enterocytozoon hepatopenaei, and is simple in preparation process, convenient to use, non-toxic and free of drug residue risk.

Description

technical field [0001] The present invention relates to a compound preparation for preventing and treating enterococcidiosis of Litopenaeus vannamei and its preparation and use method, in particular, to a preparation for preventing and treating enterozoatosis of prawns and its preparation method and application . Background technique [0002] Prawns belong to Arthropoda, Crustacea, Decapod, and Penaeidae. Because of their delicious meat, rich protein, and high nutritional value, they are popular delicacies. The prawns cultured in my country mainly include Litopenaeus vannamei, Penaeus monodon, Penaeus chinensis and Penaeus japonica. Litopenaeus vannamei has strong adaptability to salinity, can be cultured in sea and fresh water, and has relatively low requirements for feed protein. It is currently the species with the largest scale and output in my country's prawn farming, accounting for more than 70% of the total domestic prawn farming. In recent years, the output of prawn...

Problems solved by technology

Enterocytozoon hepatopenaei, newly discovered in Litopenaeus vannamei in recent years, has gradually threatened the healthy development of the shrimp farming industry. It was detected for the first time in China; the growth of prawns infected with E. hepatica slowed down, and individual sizes appeared in the affected ponds, which seriously affected the growth cycle, feed return rate and market price of prawns, and caused large economic losses to the aquaculture industry.
