Embodiment Construction

[0014] Below in conjunction with specific embodiment the present invention is described in further detail:

[0015] A feeding method for laying hens, in the feeding process, feed amount, feed nutrition and light conditions are respectively controlled as follows:

[0016] Feed amount: Chicks before 8 weeks are fed throughout the day and can eat freely; from 9 weeks to 19 weeks, they are fed every other day, and the feed amount is increased week by week. The feed amount increases from 35 grams per day. up to 60 grams per bird; from 20 weeks to 30 weeks, daily feeding was used, and the feeding amount was increased week by week to 106 grams per day; from 31 weeks to 36 weeks, daily feeding was used, and the first two weeks were kept The feeding amount was 106 grams per day, and then reduced to 98 grams per day every week; the daily feeding amount was maintained at 98 grams per day from 37 weeks to 66 weeks.

[0017] Feed nutrition: The crude protein content of the diet for chicks...

Abstract

The invention discloses a breeding method of laying hens, and relates to the field of a cultivation technique. The feeding volume, fodder nutrition and light condition are respectively controlled in a breeding process. The peak period of egg laying can be stabilized to improve production performance by keeping the weights of the laying hens in a proper scope by limit feeding; furthermore, the nutrient contents of crude protein, metabolic energy and calcium can be adjusted in the all week daily rations to ensure the nutrient balance of the laying hens; in addition, the illumination time and illumination intensity of the laying hens are controlled to enable the body maturation to be synchronous to sexual maturity of the laying hens, the time of duration of egg laying peak period can be prolonged, the egg production can be improved, and the annual average egg production of 66 weeks old can reach up to 120 eggs per laying hen.

Description

technical field [0001] The invention relates to the field of breeding technology, in particular to a method for raising laying hens. Background technique [0002] Nandan County, Guangxi is located on the edge of the Yunnan-Guizhou plateau. It is a middle-alpine region with an average altitude of 800 meters. The temperature difference between day and night is large and the rainfall is humid. There is a better preserved local chicken breed, Nandan Yao chicken, which is small in size. Thin skin, less subcutaneous fat, crisp and tender meat, delicious taste, is a popular food; but its production performance is poor, the average annual egg production at 66 weeks old is only 105 eggs per egg, low egg production, affecting It has promoted the development of Nandan Yao chicken breeding industry. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for raising laying hens to solve the problem of low egg production of...
