Laying hen breeding method

Abstract

The invention discloses a laying hen breeding method, which comprises the following steps of (1) chicken culture: lively and healthy chickens with regular size are selected, and the chickens are cultured at 36 to 37 DEG C; (2) growing period breeding: after one month, the chickens are moved out from a chicken culture room, and are bred at 21 to 24 DEG C, the breeding density is 20 to 25 chickens per square meter, the relative humidity is 55 to 60 percent, the illumination time is 8 to 10h / d, and the illumination intensity is 1 to 1.3w / m<2>; (3) egg laying period culture: the breeding density is 15 to 20 chickens per square meter, the temperature is 15 to 23 DEG C, the humidity is 60 to 70 percent, starting from 20 week old, the illumination is increased by 0.5h per week until the illumination time is 14 to 16h / d, in addition, the illumination intensity is increased to 4 to 5w / m<2>, and in four weeks before the hen elimination, the illumination time is gradually prolonged to 17h until the elimination, eggs are picked in time for creating egg-free environment; (4) hygiene and disease control: ventilation and air exchange are carried out in a henhouse in time, and air in the henhouse keeps fresh. The invention provides the healthy and scientific laying hen breeding method capable of improving the laying hen rate.

Description

technical field [0001] The invention relates to the field of breeding technology, in particular to a method for breeding laying hens. Background technique [0002] The current layer feed products are divided into premix, full-price feed and concentrated feed. Generally, only one recommended formula for premix products is designed. In different seasons, due to the different feed intake, the nutrition eaten by laying hens does not meet the nutritional requirements of laying hens. In summer, nutritional deficiencies (especially protein, calcium, and amino acids) are prone to occur, resulting in a decrease in egg production rate and poor eggshell quality. Overnutrition tends to occur in winter, resulting in overweight eggs, rectal prolapse, and increased mortality. For this reason, while improving the feeding and management level of laying hens, it is necessary to design different suggested formulas according to different seasons, so as to make laying hens nutritionally balanc...
