Pine needle soft feed capable of increasing fish culturing yield and preparation method of pine needle soft feed

Abstract

The invention discloses a pine needle soft feed capable of increasing the fish culturing yield and a preparation method of the pine needle soft feed. The pine needle soft feed consists of the following raw materials in parts by weight: 50-70 parts of fresh pine needles, 18-22 parts of cotton seed meal, 1-2 parts of semen cuscutae powder, 1-2 parts of fleeceflower root powder, 0.3-0.5 part of aspergillus glaucus bacterial liquid, 3-5 parts of puffing sesamol, 2-3 parts of yam flour, 0.5-0.8 part of candida utilis lodd. et v. rij bacterial liquid, 0.2-0.3 part of chicken powder, 0.1-0.2 part of ox bone meal, and 0.3-0.5 part of edible gelatine. The feed disclosed by the invention is soft in nature and good in palatability, has full-bodied aromatic odor, can promote the rapid growth and weight increment of fish, shortens the culture cycle, reduces the disease of the fish, increases the survival rate of the fish, and improves the nutrition and the quality of fish; the utilization rate of the feed is increased, and finally, the breeding yield is increased.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a pine-leaf soft feed for improving fish farming output 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 f...

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 a
