Pine needle soft feed for reducing fish dermatopathy and preparation method thereof

Abstract

The invention discloses pine needle soft feed for reducing fish dermatopathy and a preparation method thereof. The pine needle soft feed comprises, by weight, 50-70 parts of fresh pine needle, 14-17 parts of tofu residue, 9-11 parts of corn flour, 0.4-0.6 parts of calamus leaf, 0.3-0.5 parts of aspergillus glaucus liquid, 0.2-0.3 parts of radix sophorae flavescentis extract, 3-5 parts of molasses, 0.5-0.8 parts of a candida utilis liquid, 0.3-0.5 parts of fermented soya bean, 0.1-0.2 parts of ginger oil and 0.3-0.5 parts of edible gelatin. The pine needle soft feed is soft, has good palatability and a thick fragrance, can improve fish immunity and bacterium, fungus and protozoon resistance, can reduce fish saprolegniasis, white skin disease, red skin disease, gill rot and leprnorthsis and improves a fish culture survival rate and income.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a pine leaf soft feed for reducing fish skin diseases and a preparation method thereof. Background technique [0002] Pine leaves, bitter in taste, warm in nature, have the effects of supplementing nutrition, invigorating the spleen and regulating qi, expelling wind and dampness, killing insects and relieving itching. Modern studies have shown that pine leaves contain a variety of amino acids, macro and trace elements, vitamins, fungicides, especially carotene. In foreign countries, the use of pine leaves to feed animals has a history of many years, and the production has been industrialized. However, this technology started relatively late in my country. Most of the pine leaf raw materials in our country are treated as firewood or waste, which not only wastes resources but also creates habitats and breeding places for various forest pests, and it is easy to cause forest fir...

AI Technical Summary

Problems solved by technology

Because the processing and utilization technology of pine leaves in our country is not mature enough at this stage, the domestically developed pine leaf feed for fish still has shortcomings such as poor palatability, weak food attraction, slow growth, and long breeding cycle. Reasonable utilization of pine leaves, in order to improve the benefits of aquaculture fish farming, it is necessary to carry out in-depth research and development on pine leaves
