Special dace feed as well as preparation method and application thereof

Abstract

The invention discloses a special dace feed as well as a preparation method and application thereof. The special dace feed comprises the following raw materials in parts by weight: 5-12 parts of cuttlefish internal organ paste, 1-5 parts of fish oil, 18-26 parts of fish meal, 11-19 parts of areca peel and 23-31 parts of hibiscus mutabilis. The raw materials used for the special dace feed are environmental-friendly, free from toxic and harmful effects, broad in sources, low in price and easy to obtain; the preparation method is simple and is easy in industrialized production; when the special dace feed is used for raising parent daces, the effects of being free form residues, free from enrichment and free from pollution to breeding water bodies are achieved. In addition, the special dace feed also has the functions of promoting growth and enhancing immunity, and has higher social benefits and higher economic benefits. The special dace feed disclosed by the invention can strengthen the combination of sex hormones with target organs, so that the propagation capacity of parent daces is improved, the egg diameter and the sexual gland index of the parent daces can be enlarged, and the fertilization rate and the fry emergence rate of the parent daces can be substantially increased.

Description

technical field [0001] The invention relates to the field of feed, in particular to a special feed for dace and its preparation method and application. Background technique [0002] Dace is suitable for people with weak constitution, insufficient energy and blood, and malnutrition; it is suitable for people with hot bladder, dysuria, liver cirrhosis, ascites, and malnutrition edema. Although the reproductive technology of dace in my country is relatively mature, it mainly relies on the use of hormones or hormone analogs to induce labor. These hormones and hormone analogs such as gonadotropin-releasing hormone, dopamine antagonists, and dopamine depleting agents are chemical drugs. The long-term use of these chemicals not only leads to the decline of broodstock reproductive ability, seed degradation, environmental pollution and other problems, but also their residue and enrichment in seed will affect human health. When broodstock induce labor, the injection dose of these horm...

AI Technical Summary

Problems solved by technology

Although the reproductive technology of dace in my country is relatively mature, it mainly relies on the use of hormones or hormone analogs to induce labor. These hormones and hormone analogs such as gonadotropin-releasing hormone, dopamine antagonists, and dopamine depleting agents are chemical drugs. The long-term use of these chemicals not only leads to the decline of broodstock reproductive ability, seed degradation, environmental pollution and other problems, but also their residue and enrichment in seed will affect human health

When broodstock induce labor, the injection dose of these hormones and hormone analogues is too large or insufficient, which will easily lead to increased mortality of broodstock, lower fertilization rate and induced labor rate

In terms of use time, too early or too late will lead to failure of induced labor

In addition, inadvertent operation in the process of induced spawning will lead to broodstock damage and broodstock shock stress, resulting in non-production or dystocia, and even death of broodstock, which will bring serious economic losses to farmers.
