Novel composite enzyme preparation for aquatic product and preparing method thereof

Abstract

A composite enzyme product as the additive of forage for aquatic animals to increase the utilization rate of forage and the resistance to diseases, promote growth, and decrease the contents of organic substances, N, P, etc in excreta is proportionally prepared from beta-glucosidase, xylanase, beta-mannase, neutral phytase, amylase, neutral proteinase, acidic proteinase, antioxidant, anti-mildew agent. Its preparing process is also disclosed.

Description

technical field [0001] The invention relates to an animal feed additive and a preparation method thereof, in particular to an aquatic compound enzyme preparation added in aquatic animal feed and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, people's demand for some special aquatic animals such as turtles is increasing, and the number of artificial breeding is also increasing. However, the main protein source in turtle feed is high-quality white fish meal, which accounts for more than 60% of the feed composition. The protein feed resources are limited, and the low utilization rate of protein feed has caused serious waste of resources, and caused a certain degree of damage to the water body breeding environment. pollute. With the continuous development of the aquaculture industry, the demand for high-quality protein resources is increasing, and the shortage of protein resources is becoming more and more serious;...

Problems solved by technology

However, the main protein source in turtle feed is high-quality white fish meal, which accounts for more than 60% of the feed composition. The protein feed resources are limited, and the low utilization rate of protein feed has caused serious waste of resources, and caused a certain degree of damage to the water body breeding environment. Pollution

With the continuous development of the aquaculture industry, the demand for high-quality protein resources is increasing, and the shortage of protein resources is becoming more and more serious; and the digestion and absorption utilization rate of plant-based protein feed resources by aquatic animals is low, so their feeding effect is poor. The proportion of application in aquatic feed is relatively low; and the phenomenon of reduced feed efficiency due to unreasonable feed structure and improper feed preparation is common, which not only wastes a lot of precious feed resources, but also causes a certain degree of damage to the ecological environment of breeding
