Problems solved by technology

However, in my country's layer hen breeding industry, no matter which growth stage the layer hens are in, they are kept in cages in the same growth environment. This intensive breeding method has the disadvantages of poor feeding environment, simple feeding facilities, single feed formula, and poor management. Defects such as low technology lead to low laying performance of laying hens, high morbidity and mortality, and poor breeding benefits, which cannot meet the requirements of high-yielding laying hens

Abstract

The invention discloses a laying hen breeding method. The growth cycle of laying hens is divided into eight stages, namely 0-3 weeks, 4-6 weeks, 7-10 weeks, 11-15 weeks, 16 weeks-80% laying rate, 80% laying rate-40 weeks, 40-60 weeks and 60 weeks-weeding out, different feed nutritive standards and feeding environments are adopted for the eight stages, and the feeding environments include temperature, humidity, illumination and air quality. According to the laying hen breeding method, proper feeding environments and feed nutritive standards are selected in a targeted mode according to the different stages of growth of the laying hens, breeding is conducted scientifically, the production time of the laying hens is 7-15 days earlier than that of an ordinary feeding method, the sum of the death rate and the elimination rate is not higher than 5%, the laying rate peak stage of 90% and above of the laying hens is as long as 12 months, the income from each laying hen in one cycle can be increased by 15-20 yuan, maximization of production performance of the laying hens is achieved, and the laying hen breeding method is worthy of application and popularization.

Description

technical field [0001] The invention relates to the technical field of poultry breeding, in particular to a method for raising laying hens. Background technique [0002] With the development of laying hen breeding technology in our country, the laying performance of laying hens has gradually improved, the body weight and feed consumption have gradually decreased, and the benefits of laying hen farming have been improved to a certain extent. However, in my country's layer hen breeding industry, no matter which growth stage the layer hens are in, they are kept in cages in the same growth environment. This intensive breeding method has the disadvantages of poor feeding environment, simple feeding facilities, single feed formula, and poor management. Defects such as low technology lead to problems such as low laying performance of laying hens, high morbidity and mortality, and poor breeding benefits, which cannot meet the requirements of high-yield laying hens. How to select the...
