Soft pine needle feed capable of accelerating protein accumulation of fries and preparation method of soft pine needle feed

Abstract

The invention discloses a soft pine needle feed capable of accelerating the protein accumulation of fries and a preparation method of the soft pine needle feed. The soft pine needle feed consists of the following raw materials in parts by weight: 50-70 parts of fresh pine needles, 18-24 parts of soybean meal, 4-8 parts of blood powder, 0.5-0.6 part of cinnamomi cortex pulveratus, 0.3-0.5 part of aspergillus glaucus liquid, 2-3 parts of common curculigo leaf meal, 2-3 parts of soy sauce, 0.5-0.8 part of candida utilis liquid, 0.3-0.5 part of a pork extract, 0.2-0.3 part of chili sauce, and 0.3-0.5 part of edible gelatine. The feed disclosed by the invention is soft, is good in palatability, has full-bodied aromatic odor, can improve the utilization efficiency of the proteins by the fries, and accelerates the absorption, the transformation and the accumulation of the proteins in bodies, promotes the fries to rapidly grow and rapidly gain weight, and increases the survival rate of the fries.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a pine leaf soft feed which accelerates protein accumulation 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 ca...

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
