Abstract

The invention discloses a composite preparation for killing prawn enterocytozoon hepatopenaei and an application method of the composite preparation. The composite preparation is prepared from the following raw materials by mass percent: 4.5 to 6.0 percent of albendazole, 5.0 to 8.0 percent of betel nut extract, and 86.0 to 90.5 percent of corn starch auxiliary materials. The betel nut extract is extracted in a laboratory and obtained by virtue of boiling, concentrating and freeze-drying, and one kilogram of betel nuts can be prepared into 100 grams of extract. The composite preparation has the beneficial effects that the composite preparation is safe to a target animal; by using the composite preparation, the prawn enterocytozoon hepatopenaei can be effectively killed, and the requirement for preventing the enterocytozoon hepatopenaei in the cultivation process of prawns can be met; and the preparation process is simple, the use is convenient, and the application prospect is good.

Description

technical field [0001] The invention relates to a compound preparation, in particular to a compound preparation for killing prawn enterococci, and a method for using the compound preparation. 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 largest species of shrimp farming in my country and accounts for more than 70% of the total domestic shrimp farming. In recent years, the output of prawn farming in my country is about 1.5 million tons, and the aquaculture area is about 240,000 hectares. The prawn farming industry has become an im...
