Granular premixed feed for laying hens and production process of granular premixed feed for laying hens

Abstract

The invention relates to a granular premixed feed for laying hens and a production process of the granular premixed feed for the laying hens. The granular premixed feed is prepared from, by weight, 0.25-2.5% of microencapsulated vitamins, 0.5-5% of controlled-release trace elements, 0-30% of mono-dicalcium phosphate, 0.05-0.5% of granular phytase, 0-15% of sodium chloride, 1.2-12% of methionine, 0.1-1% of glucose oxidase, 13-70% of nucleotide residues and 20-50% of gravels. The premixed feed is granular, the 8-mesh screen passing rate is 100%, and the 100-mesh standard screen passing rate is not higher than 10%. The feed is granular, dust, nutritional component scattering and environment pollution in a production and utilization process are avoided, and environmental friendliness and scientific proportioning are realized; by mutual promotion of functional materials, the component utilization rate is increased, the egg laying rate and egg weight are increased, and the death and cullingrate is decreased.

Description

technical field [0001] The invention relates to the field of feed production, in particular to a granular premixed feed for laying hens and a production process thereof. Background technique [0002] Eggs are a protein source food that people often eat in daily life, and the quality and yield of eggs are the most concerned issues for layer hen farmers. Premixed feed is an important part of complete feed, which is a uniformly stirred mixture of various additive raw materials and carriers. The important indicators for evaluating the premixed feed are the absorption utilization rate and functional potency, and the factors affecting the absorption utilization rate and functional potency mainly include the ingredient formula and the form of the premixed feed. At present, there have been many reports on the premixed feed for laying hens disclosed in the prior art, most of which are researches on the ratio of ingredients, such as CN103947843A, CN1927028A, CN107149050A, CN108740548...

Problems solved by technology

At present, there have been many reports on the premixed feed for laying hens disclosed in the prior art, most of which are researches on the ratio of ingredients, such as CN103947843A, CN1927028A, CN107149050A, CN108740548A, etc. The feed is used to improve the anti-stress function or intestinal function of laying hens, so as to improve the production performance of laying hens, but the above reports on the premix have the following defects: 1. It will generate dust during use, resulting in nutrient loss And pollute the environment; 2. The choline chloride and trace elements used in the premixed feed for laying hens have a destructive effect on vitamins; 3. The powdered premixed feed for laying hens is easy to grade during the mixing process with other raw materials, and the mixing uniformity Poor; 4. The use of Chinese herbal medicine needs to be strictly controlled
