Problems solved by technology

However, in the grass carp breeding process, there are many diseases and poor stress resistance, resulting in low survival rate of grass carp, especially juvenile fish, the general survival rate is only 40%.
[0003] In order to improve the survival rate of grass carp seedlings, farmers usually use the method of adding some antibiotics to the feed, but excessive use of antibiotics will not only pollute the water body, produce drug residues, affect human health, but also cause grass carp to develop drug resistance The disease prevention effect is getting worse and worse, or even ineffective, which makes the incidence of disease in fish schools higher and higher, and seriously reduces the breeding efficiency of grass carp

Abstract

The invention belongs to the technical field of aquaculture, and specifically discloses a feed capable of improving survival rate of juvenile grass carps. The feed capable of improving the survival rate of the juvenile grass carps disclosed by the invention is mainly composed of the following ingredients in certain parts by weight: a basal feed, a first additive, a second additive and a microbialagent; and the feed is prepared by the following steps of carrying out mixed fermentation, regulating, and granulation. The first additive comprises the following raw materials in certain parts by weight: vitamin C, calcium dihydrogen phosphate, and chitosan; and the second additive comprises the following raw materials in certain parts by weight: herba houttuyniae, liquorice roots, coix seeds, dianthus superbus, lygodium japonicum, and so on. The feed capable of improving the survival rate of the juvenile grass carps disclosed by the invention is full and comprehensive in nutrition, good in environment protection properties, and low in cost, and capable of effectively improving body immunity and anti-stress ability of the grass carps; and thus, survival rate of the juvenile grass carps iseffectively improved so as to facilitate culture benefits of the grass carps.

Description

【Technical field】 [0001] The invention relates to the technical field of aquatic feed, in particular to a feed for improving the survival rate of juvenile grass carp and a preparation method thereof. 【Background technique】 [0002] Grass carp is one of the four major fish species in China. It is rich in nutrition and has high economic value. It is one of the most widely farmed freshwater species in China, with an annual output of more than 4 million tons. However, there are many diseases and poor stress resistance in the grass carp breeding process, resulting in a low survival rate of grass carp, especially juveniles, whose survival rate generally only reaches 40%. [0003] In order to improve the survival rate of grass carp seedlings, farmers usually use the method of adding some antibiotics to the feed, but excessive use of antibiotics will not only pollute the water body, produce drug residues, affect human health, but also cause grass carp to develop drug resistance Sex...
