Pine needle soft forage for improving fry survival rate and preparation method thereof

Abstract

The invention discloses pine needle soft forage for improving a fry survival rate and a preparation method thereof. The pine needle soft forage is prepared from 50-70 parts by weight of fresh pine needles, 15-18 parts by weight of cotton seed meal, 0.6-0.8 parts by weight of Sedum sarmentosum Bunge powder, 0.4-0.6 parts by weight of rhizoma atractylodis powder, 0.3-0.5 parts by weight of aspergillus glaucus liquid, 0.1-0.2 parts by weight of Chinese prickly ash seed powder, 1-2 parts by weight of mung bean flour, 1-2 parts by weight of a candida utilis liquid, 3-4 parts by weight of expanded rice bran, 0.2-0.3 parts by weight of an onion juice and 0.3-0.5 parts by weight of edible gelatin. The pine needle soft forage is soft, has a good taste and a thick fragrance, can improve fry immunity, can reduce fish diseases, can improve a fry survival rate, can promote fry growth and weight increasing, can promote fry growth and weight increasing, can shorten a culture period and can improve a culture yield.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a pine leaf soft feed which improves the survival rate 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 fo...

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
