Special complex enzyme preparation for turtle and eel feeds

Abstract

The invention relates to the field of feed additives, and particularly relates to a special complex enzyme preparation for turtle and eel feeds. The special complex enzyme preparation for turtle and eel feeds contains 5000-8000 U / g of acid protease, 3000-6000 U / g of neutral protease, 1000-1000 U / g of xylanase, 15000-18000 U / g of cellulase, and 500-800 U / g of pectinase. The complex enzyme preparation disclosed by the invention does not contain alpha-amylase and glucoamylase, so that the influence on the viscoelasticity of feeds is avoided or reduced; the digestibility of turtles and eels on feed proteins is improved, the growth of turtles and eels is promoted, the weight gain rate is improved, the feed coefficient is reduced, the economic benefit is increased, the discharge of fecal nitrogen and fecal phosphorus is reduced, and energy conservation and environmental protection are achieved; and due to the balanced proportioning of several non-starch polysaccharide enzymes, plant cell walls and various anti-nutritional factors are effectively degraded.

Description

technical field [0001] The invention relates to the field of feed additives, in particular to a special compound enzyme preparation for soft-shelled turtle eel feed. Background technique [0002] Soft-shelled turtles and eels have a very high demand for feed protein, generally around 44%, which is 2-3 times that of livestock and poultry animals. Although soft-shelled turtle eels are aquatic animals with a stomach, their digestive system is inferior to that of livestock and poultry, and the endogenous enzymes are not enough to degrade all the protein in the feed. Proteins that cannot be digested and utilized are excreted with feces, resulting in waste of resources and environmental pollution. In addition, with the decline of white fishmeal resources and the rise in prices in recent years, China has carried out research on the substitution of red fishmeal, domestic fishmeal for white fishmeal and imported fishmeal, and has begun to gradually increase the use of plant-based ra...

AI Technical Summary

Problems solved by technology

Existing enzyme preparations may degrade α-starch and gluten, reduce the viscoelasticity of the feed, and affect the stability of the feed in water

In addition, the feed protein of soft-shelled turtle eel is higher than that of livestock and poultry and general fish, but the plant raw materials are less, the existing enzyme spectrum and enzyme activity are not suitable, and the best effect cannot be achieved
