[0002] At present, there are various breeding methods and models of laying hens, but they are difficult to meet the current economic development needs of our country. It is also gradually in line with international standards, but there is still a huge gap (Table 1). In order to improve the breeding efficiency and narrow the gap with the international advanced level, it is urgent to promote a high-efficiency laying hen breeding model.

Embodiment 1
[0120] A laying hen breeding method, which divides the breeding stages of laying hens into six stages and sets the basic nutritional requirements in each stage, specifically including:
[0121] (1) With the age of 0 to 15 days as the opening stage, feed a complete nutritional feed with a mass fraction of protein of 20%, energy of 2900 kcal / kg, a mass fraction of methionine of 0.45%, and a mass fraction of lysine 1.1%, the mass fraction of calcium is 0.9%, the mass fraction of available phosphorus is 0.45%, and the mass fraction of salt is 0.3%. Choose more high-quality raw materials with high nutrition, easy digestion and absorption, and less anti-nutritional factors, such as puffed corn, puffed soybeans, soybean milk powder, imported fish meal, immunoglobulin, etc. At this stage, the daily feed intake is about 10 grams / bird / day.
[0122] (2) Taking 16-70 days as the brooding stage, 16-35 days-old full-price nutritious feed, wherein the mass fraction of protein is 18.5%, the ...
Embodiment 2
[0136] The full-price nutrient feed in stage (4) in Example 1 was replaced with the following formula, and the others were the same as in Example 1. The formula includes the following components by weight:

Abstract
The invention discloses a high-efficiency laying hen breeding method, in particular to a technical scheme of laying hens breeding goals, nutritional levels and key control points in different breeding stages throughout the whole process. 16-70 days is the brooding period, (3) 71-112 days is the rearing period, (4) 113-220 days is the expected laying period, (5) 221-580 days is the egg production peak In the initial stage, after the applicant's long-term practice and experience, the whole breeding stage of laying hens is reasonably divided into at least five stages. Wherein, aiming at the growth characteristics and nutritional requirements of laying hens in each stage, the present invention designs reasonable nutritional requirements and stipulates the key points of operation in each stage, so as to improve breeding benefits.
Description
technical field [0001] The invention relates to the technical field of poultry breeding, in particular to a method for breeding laying hens. Background technique [0002] At present, there are various breeding methods and models of laying hens, but they are difficult to meet the current economic development needs of our country. It is also gradually in line with international standards, but there is still a huge gap (Table 1). In order to improve the breeding efficiency and narrow the gap with the international advanced level, it is urgent to promote a high-efficiency laying hen breeding model. This requires us to constantly explore and adjust the breeding mode or method in the process of laying hen breeding. [0003] Table 1: Differences between my country's laying hen breeding and foreign countries (species: Hailan brown; breeding days 500 days old) [0004] different regions and levels Chinese public foreign advanced Egg production (catties) ...
