Feed capable of promoting growth of freshwater aquaculture fish

Abstract

The invention discloses a feed capable of promoting growth of freshwater aquaculture fish. The feed comprises the following components in parts by weight: 90-100 parts of an organic fertilizer, 50-60parts of modified soybean meal powder, 40-45 parts of modified bran, 5-10 parts of liposome, 40-50 parts of fish internal organ oil, 20-30 parts of fish protein hydrolyzate, 14-18 parts of alpha-starch, 3-4 parts of yeast cell walls, 2-3 parts of dried orange peel powder, 0.5-0.8 part of functional polypeptide, 2-3 parts of multiple vitamins, 3-4 parts of multiple minerals, 5-6 parts of a growth promoting agent and 0.08-0.1 part of a preservative. The feed has the beneficial effects that the feed is comprehensive and balanced in nutrients, is rich in nutrient elements necessary for growth anddevelopment of the freshwater fish, can attract the fish to enable the fish to surround the feed, and can promote the fish to eat. The endocrine system of the fish can also be stimulated, the utilization efficiency of the feed is improved, and the production performance of the fish can be improved. The feed is a comprehensive, efficient and safe feed capable of promoting the growth of the freshwater aquaculture fish.

Description

technical field [0001] The invention relates to the field of fish feed, in particular to a feed for promoting the growth of freshwater cultured fish. technical background [0002] Primary freshwater fish: fish that can only live in freshwater for a lifetime. It accounts for 33.1% of the total global fish, about 8600 species. Secondary freshwater fish: Fishes that live in freshwater for most of their life, occasionally move or live in brackish water or sea water. It accounts for 8.1% of the total global fish, about 2100 species. Peripheral freshwater fish: fish that live in seawater or brackish water, and whose life history will also live in freshwater, or enter brackish water. Including anadromous fish, marine fish and marine fish that occasionally enter rivers to live. Accounting for 0.6% of the total global fish, about 160 species. Most freshwater fish have special colors and markings, or body colors consistent with the surrounding environment, which can hide themselv...

[0005] The Chinese invention patent of CN 103340334 B discloses a freshwater fish feed and its preparation method. The invention method uses imported fish meal, flour, potato starch, brewer's yeast, soybean meal, peanut meal, rapeseed cake, corn meal, cooked Egg protein, meat floss powder, liquid phytase, non-starch polysaccharide enzyme, glutamine, probiotics and immune polysaccharides are pulverized and compounded to prepare freshwater fish feed, which can meet the nutritional needs of freshwater fish, improve the immunity of freshwater fish, and promote Intestinal absorption improves the production performance of freshwater fish, but the imported fish meal in the inventive method is expensive, and soybean meal and peanut meal are added to the feed without fermentation, urease, trypsin inhibitor, water in soybean meal and peanut meal Anti-nutritional factors such as threose and raffinose will reduce the nutritional content of raw materials, and even cause indigestion and allergic reactions in fish, so their promotion value is not great
