Pine needle soft feed for removing fish intestinal tract heavy metal ions, and preparation method thereof

Abstract

The present invention discloses a pine needle soft feed for removing fish intestinal tract heavy metal ions, and a preparation method thereof, wherein the raw materials comprise, by weight, 50-70 parts of fresh pine needle, 17-20 parts of perilla frutescens seed meal, 2-3 parts of green tea residue, 1-2 parts of aloe leaf powder, 0.3-0.5 part of a Aspergillus glaucus liquid, 2-3 parts of oat bran, 0.4-0.6 part of active white clay, 0.2-0.3 part of common vladimiria root powder, 0.5-0.8 part of a Candida utilis liquid, 0.2-0.3 part of bamboo charcoal powder, 0.04-0.08 part of old vinegar, and 0.3-0.5 part of edible gelatin. According to the present invention, the feed has characteristics of softness, excellent palatability, rich aroma, strong disease resistance, fish immunity enhancing, fish bacterial infection reducing, detoxification and toxin elimination effects on heavy metal ions, heavy metal ion accumulation reducing, and fresh fish meat nutrition maintaining.

Description

Technical field [0001] The invention relates to the technical field of aquaculture, in particular to a loose leaf soft feed for removing heavy metal ions from fish intestines and a preparation method thereof. Background technique [0002] Pine leaves, bitter in taste, warm in nature, have the effects of supplementing nutrition, strengthening the spleen and regulating qi, dispelling wind and dampness, killing insects and relieving itching. Modern research shows that pine leaves contain a variety of amino acids, macro and trace elements, vitamins, and fungicides, especially carotene. In foreign countries, pine leaves have been used to feed animals for many years, and production has been industrialized. However, this technology started relatively late in my country. Most of the raw materials of pine leaves in our country are treated as firewood or waste, which wastes resources and creates habitats and breeding places for various forest pests. It is also easy to cause forest fires. ...

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
