Pine needle soft feed for improving the nutritional quality of fish and preparation method thereof

Abstract

The invention discloses a pine needle soft feed for improving the nutritional quality of fish and a preparation method thereof. The soft feed is prepared from the following raw materials in parts by weight: 50-70 parts of fresh pine needles, 16-20 parts of barley flour, 7-9 parts of chicken blood powder, 2-3 parts of apple leaf powder, 0.3-0.5 part of aspergillus glaucus bacterial liquid, 2-3 parts of spinach leaf powder, 1-2 parts of molasses, 0.5-0.8 part of candida utilis bacterial liquid, 0.1-0.2 part of patchouli oil, 0.2-0.3 part of duck bone extract and 0.3-0.5 part of edible gelatin. The feed has soft texture, excellent palatability and rich fragrant smell, and can be used for reducing oxygenolysis of amino acid and fat in a fish body, reducing accumulation of harmful substances in the body, accelerating discharge of metabolic waste, improving the nutritional quality of fish and improving the tasty degree of fish and fish soup.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a pine leaf soft feed for improving the nutritional quality of fish meat 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 ...

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
