The duck production period of fire ducks can be divided into three stages: the initial stage of laying (21 to 26 weeks of age), the peak period of egg production (27 to 60 weeks of age), and the late stage of laying (61 to 70 years of age). Weekly age). If you neglect to manage or improperly manage the egg production period, it will not only affect the egg production of fire ducks, but also cause some diseases. The egg production of fire ducks in the early stage of the production of eggs increases day by day, and the breeding density, feed and feeding methods of fire ducks should be kept stable, and avoid shortening the light time. Weak light was given in the evening and the fire duck could see the nests, troughs and sinks as the standard. The breeding density should be 4 to 5 per square meter. Feeding methods can be selected for free feeding and manual feeding (4 times a day). The protein content in the feed should be above 18%, and the energy should be above 11.5 megajoules per kilogram, so that the duck group can reach the peak of egg production as soon as possible. During the peak period of egg production, the fire duck has large egg production intensity, consumes much, and is very sensitive to environmental changes and feed changes. Feeding methods should be free to eat. Daylight hours are stable at 16.5 hours. The breeding density is 4 to 5 per square meter. This stage requires dietary crude protein content of more than 19%. In the daily management, we must keep abreast of the health status of the ducks, observe whether the eggshell quality has changed significantly, whether the egg production time is concentrated, and whether the feathers are clean and tidy. The egg production rate of ducks in the fire ducks at this stage of the late stage of laying is reduced. If the breeding and management are properly conducted, the average egg production rate of duck groups can still be maintained at 75% to 80%. The feeding amount should be adjusted according to the weight of the duck group and the change in the egg production rate. The lighting time is appropriately extended and is stable at 17 hours per day. It is forbidden to shorten the lighting time.
