Embodiment 1

[0014] A breeding method for laying hens, brooding period: 24h light time in the first 3 days, reduced to 18h light time on the 4th day, and reduced to 12h light time at the end of the brooding period, feeding the brooding period feed, the brooding period feed is the following raw materials Mixture: 60 parts of corn, 12 parts of wheat bran, 21 parts of soybean cake, 2 parts of calcium hydrogen phosphate, 1.8 parts of stone powder, 0.6 parts of table salt, 0.1 part of vitamin C, 0.5 parts of lysine, 0.2 parts of vitamin E, vitamin A0 .3 parts, 0.08 parts of threonine, and 0.5 parts of choline. Breeding period: adjust the stocking density during the growing period, and feed the feed during the growing period. The feed during the growing period is a mixture of the following raw materials: 100 parts of corn, 12 parts of flour, 56 parts of soybean meal, 80 parts of rice, 35 parts of rice bran, and 50 parts of palm kernel meal , 40 parts of peanut straw, 7 parts of papaya seeds, 5 p...

Embodiment 2

[0018] A raising method for laying hens, the brooding period: the first 3 days of 23h light time, the 7th day light time is reduced to 18h, the light time is reduced to 12h at the end of the brooding period, and the brooding period feed is fed, and the brooding period feed is the following raw materials Mixture: 60 parts of corn, 12 parts of wheat bran, 21 parts of soybean cake, 2 parts of calcium hydrogen phosphate, 1.8 parts of stone powder, 0.6 parts of table salt, 0.1 part of vitamin C, 0.5 parts of lysine, 0.2 parts of vitamin E, vitamin A0 .3 parts, 0.08 parts of threonine, and 0.5 parts of choline.

Abstract

The invention discloses a breeding method of laying hens. The breeding method comprises steps as follows: in the brooding period, the illumination time is 23-24 hours for the first three days, is reduced to 18 hours from the fourth day to the seventh day and is 12h when the brooding period is ended, and the hens are fed with fodder for the brooding period; in the growing period, the breeding density is adjusted, and the hens are fed with fodder for the growing period; in the egg laying period, the temperature in a hen house is kept in the range of 13 DEG C-23 DEG C, the relative humidity is 55%-60%, the illumination time is 16 hours, and daily nutrition is guaranteed. According to the breeding method of the laying hens, formulas of the fodder for the brooding period and the fodder for the growing period are improved, the immune function of the laying eggs is adjusted, the protein quality of eggs laid by the laying hens is improved, the fodder cost is low, the nutrition is rich, the nutritional requirement of the laying hens is met, and the egg production is improved.

Description

technical field [0001] The invention belongs to the field of poultry breeding, in particular to a method for raising laying hens. Background technique [0002] The first few weeks before the laying hens are laid is the transition period for the hen from the growth period to the laying period. At this stage, not only a series of tasks such as transfer to cages, selection and elimination, immunization, feed replacement, and increased light are required, which will cause great stress to the chickens. During this period, the physiological changes of the hens are severe, sensitive, and less adaptable. Weak, poor disease resistance, if not properly fed, can easily affect egg production performance. [0003] In the prior art, in the early stage of laying hens, that is, from the start of laying to the peak of laying eggs (40 weeks of age), the laying rate is greater than 80%. During this period, the nutritional content of protein and calcium in the diet should follow the egg laying...
