Problems solved by technology

However, there are mixed feed compound enzyme products for laying hens on the market, most of which are formulated to solve the anti-nutritional effect of non-starch polysaccharides in laying hen diets, often ignoring the physiological characteristics of the digestive tract of laying hens and corn, The digestion and utilization rate of conventional nutrients in soybean meal raw materials. Therefore, the current use of enzyme preparations is not ideal, and it cannot achieve the effect of improving the egg production performance of laying hens and reducing feed production costs and use costs.

Abstract

The invention discloses a compound enzyme preparation for a hen feed as well as a production method and an application thereof. The enzyme activity composition of the compound enzyme preparation comprises 12000-15000 U / g of xylanase, 1000-1200 U / g of beta-glucanase, 500-600 U / g of cellulose, 500-750 U / g of beta-mannanase, 500-750 U / g of pectinase, 3000-4000 U / g of acid protease, 1000-1200 U / g of neutral protease, 750-1000 U / g of mesophilic alpha-amylase, 1500-2000 U / g of fungal alpha-amylase and 2000-2500 U / g of glucoamylase. The compound enzyme preparation is diluted by using a mixture of equal mass parts of corn flour and calcium sulphate; and the addition amount of the product of the invention is 150-200 g per ton of complete formula feed.

Description

technical field [0001] The invention relates to a feed compound enzyme preparation for laying hens, a production method and application thereof. Background technique [0002] At present, the total egg production and the number of laying hens in my country rank first in the world, and have maintained a rapid growth trend in the past 30 years. With the development of the laying hen industry, the traditional concept of simply pursuing high yield of laying hens is high efficiency is changing to the concept of not only reducing production costs, but also improving feeding management and disease prevention, paying attention to the feed-to-egg ratio, and pursuing high efficiency in an all-round way. change. How to reduce the cost of feed use, feed manufacturers adjust the feed formula in an all-round way, and use a large number of unconventional raw materials (feed materials other than corn and soybean meal) such as cotton meal, rapeseed meal, corn processing by-products, fiber fe...
