Micro-ecological pollution-free compound feed suitable for young ricefield eels, and preparation method of compound feed

Abstract

The invention relates to a micro-ecological pollution-free compound feed suitable for young ricefield eels, and a preparation method of the compound feed. The micro-ecological pollution-free compound feed is prepared from the following raw materials: fish meal, wheat, bean pulp, extruded soybeans, fish oil, spray-dried animal blood cells, lecithin oil, calcium dihydrogenphosphate, 50% choline chloride, 35% Vc phosphate, enzymic preparation specially used for aquatic products, glossy privet fruit, micro-ecological preparation for aquatic products and compound premix specially used for alepidote fishes. The micro-ecological pollution-free compound feed is prepared by strictly screening the raw materials by a reasonable preparation method, is high in pertinence, is especially suitable for feeding the young eels, and is balanced and complete in nutrition; after the compound feed is adopted, the immunity, the disease resistance and the anti-stress capability of the young eels can be improved, the nutrition needed by the growth and development of the young eels can be fully guaranteed, the young eels can rapidly and healthily grow, and the limited growth speed is greatly increased; furthermore, in a preparation process, the nutrient substances are protected from damage by high temperature to the utmost extent; the micro-ecological pollution-free compound feed is low in product cost, high in efficiency, stable in quality, convenient to store and free from adverse effect.

Description

technical field [0001] The invention relates to an aquaculture feed, in particular to a pollution-free microecological rice field eel compound feed suitable for juvenile eels, and also relates to a preparation method of the feed. Background technique [0002] Rice field eel is a scaleless aquatic animal with long feeding cycle and slow growth rate. Due to the high density of artificial breeding and the change of water quality, diseases often occur. After a market survey, it was found that most households feed rice field eels with pig blood, mussel meat, small miscellaneous fish and shrimp, etc. This feeding method is not comprehensive in nutrition, the feed conversion rate is low, and the degree of deterioration of water quality is increased, resulting in frequent disease of rice field eels. , the growth rate is slow, and the feeding cost is high, so that the economic benefits of the farmers are seriously damaged. [0003] In recent years, aquaculture workers in our country...

[0002] Rice field eel is a scaleless aquatic animal with long feeding cycle and slow growth rate. Due to the high density of artificial breeding and the change of water quality, diseases often occur

After a market survey, it was found that most households feed rice field eels with pig blood, mussel meat, small miscellaneous fish and shrimp, etc. This feeding method is not comprehensive in nutrition, the feed conversion rate is low, and the degree of deterioration of water quality is increased, resulting in frequent disease of rice field eels. , the growth rate is slow, and the feeding cost is high, which seriously damages the economic benefits of farmers

[0003] In recent years, aquaculture workers in our country have carried out a large number of popularization and use of eel compound feed, and have also done a large number of experiments on feed conversion rate, and have made great progress. However, due to the breeding conditions, water quality conditions and geographical climate conditions in different regions , its applicability is not strong
