Pine needle soft feed for promoting fry growth and preparation method thereof

Abstract

The invention discloses pine needle soft feed for promoting fry growth and a preparation method thereof. The pine needle soft feed comprises, by weight, 50-70 parts of fresh pine needle, 15-20 parts of soybean meal, 5-8 parts of shrimp meal, 0.2-0.3 parts of table salt, 0.3-0.5 parts of an aspergillus glaucus bacterial liquid, 0.4-0.8 parts of haw powder, 1.2-1.6 parts of powder of root of kudzu vine, 0.5-0.8 parts of a candida utilis liquid, 0.1-0.2 parts of cream, 0.1-0.2 parts of carrot extract and 0.3-0.5 parts of edible gelatin. The pine needle soft feed is soft, has good palatability and a thick fragrant smell, can promote fry growth and weight increasing, can improve a fry survival rate, can reduce fry diseases and death, can improve a feed utilization rate and can reduce a feed coefficient.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a pine leaf soft feed for promoting the growth of fry 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
