Egg-laying group "six to"
The process of changing laying hens from laying to laying hens is called turning. A good grasp of the group can allow the laying hens to open early and produce more eggs. First, the time should be appropriate. Laying hens usually start production around the age of 20 weeks. In order to become familiar with the environment as soon as possible and make them a harmonious group, they usually need to be transferred at the age of 18 weeks. Otherwise, the egg production will be affected. Second, the chicken coop environment should be done well. In winter, 2 to 3 days before the laying hens enter the house, the hen house should be warmed up in advance so that it is basically the same temperature as the original broiler house. The field is sterilized with 40% formaldehyde solution or 50% sulphate solution. Third, prevent stress. The transfer work is carried out during the warm noon in winter and in the cool morning in summer. Bring the chicken to an empty stomach before switching to the group. Add appropriate amount of antibiotics to the feed 3 to 5 days after the transfer, so as to prevent the chicken from adapting to the environment. Fourth, we must rationally group. Chickens should be inspected before the swarm and grouped according to the size of the chickens in order to take relative management measures. Fifth, good management of feeding and management. When the chicken production rate reaches 5%, it is necessary to timely feed the layer chicken feed. Changing feeding requires gradual addition of layer chicken feed during the rearing period, all of which is replaced with layer chicken feed after 1 week. From the age of 19 weeks, the light is kept for 10 hours every day; from 20 weeks of age, the light is increased every day for 30 minutes until it reaches the light for 17 hours per day. Six, add vitamins. After 3 to 5 days after the laying hens are transferred, appropriate amounts of multivitamins are added to the layer chicken feed to increase the disease resistance of the chickens.
