Problems solved by technology

[0003] Litopenaeus vannamei feed in the prior art is a general-purpose feed used for the entire breeding cycle. Most of the feed is formulated from a nutritional point of view, and has no selectivity and adaptability to the breeding process. Considerations for improving the disease resistance of prawns less, leading to a higher incidence of Litopenaeus vannamei in the breeding process, resulting in the failure of shrimp farming, which directly affects the economic benefits of farming

Abstract

The invention discloses a litopenaeus vannamei boone anti-disease compound feed, which is characterized by consisting of a feed composition I, a feed composition II and a feed composition III which are compounded. The invention also relates to a feeding method for the compound feed, which comprises the following steps of: at the initial culture stage, feeding the feed composition I when the length of the shrimp body is 1 to 6 centimeters; at the middle culture stage, feeding the feed composition II when the length of the shrimp body is 6 to 8 centimeters; and at the later culture stage, feeding the feed composition III when the length of the shrimp body is over 8 centimeters. The anti-disease compound feed can remarkably enhance the pathogenic tolerance of the litopenaeus vannamei boone, improve the survival rate of the bred litopenaeus vannamei boone and increase the breeding yield of the litopenaeus vannamei boone. The compound feed has the advantages of easily-obtained raw materials, simple production process, stable quality, capability of providing balanced nutrient components, good palatability and easy digestion and absorption, effectively solves the problem of easy attack of the litopenaeus vannamei boone under artificial culture conditions, and can be applied to culture production of the litopenaeus vannamei boone in large scale.

Description

technical field [0001] The invention relates to a breeding feed, in particular to a compound feed suitable for disease resistance of Litopenaeus vannamei. The invention also relates to a feeding method of the compound feed. Background technique [0002] Shrimp farming is generally divided into three stages artificially, namely the initial stage of cultivation, the middle stage of cultivation and the late stage of cultivation. Normally, in the early stage of prawn farming, prawns grow rapidly and the incidence of disease is low; while in the middle and late stages of prawn farming, especially in the middle stage of aquaculture, prawn farming areas are generally in high temperature weather, and under the dual stress of high temperature and potential pathogens, prawn Very easy to get sick. [0003] Litopenaeus vannamei feed in the prior art is a general-purpose feed used for the entire breeding cycle. Most of the feed is formulated from a nutritional point of view, and has no...
