Personnel management: Intensify the training of staff skills and responsibility before entering the chicken. In the first four weeks, it is generally required to close broods, implement basic biological safety measures, and strictly prevent epidemics and sanitization. Temperature management: Pay attention to control the temperature of the brooding house, especially the temperature of the chicken back under the brooding umbrella (32-35°C for the first three days) and the temperature of the litter (generally between 28-31°C) and the temperature of the drinking water (generally Requirements 26-28 °C suitable), humidity (60-70%) and ventilation work, timely feeding of chickens and water, and give sufficient time and intensity of light. Brooding Brooding It is recommended to use a brooding umbrella for temperature brooding, and the results will be better. Feed Management: From the very first day of the Rohman brown breeder chicken, it is necessary to provide chicks with high-energy (2900-2950 kcal/kg), high-protein (21%), high-quality, and balanced nutritional materials (can also be used The broiler chicks were prepared until four weeks ago with the purpose of having a good skeleton development. Less feed Tim, stimulate appetite, so that it can reach the standard weight as soon as possible. A clean tray is provided for every 50 chicks and a small number of feedings are used in the first few days. To allow chicks to learn to use common feeding equipment as soon as possible, after 3 days of coccidia immunization, change to a small barrel. Male and female feed separately, due to the smaller size of the male and female, if polyculture is started at the beginning, the body size of the male chick will not be properly developed within 4 weeks of age, affecting the subsequent fertilization rate. Developmental characteristics and requirements suggest better brooding. Drinking water management: Before feeding, let the chicken drink cold water for 2-3 hours first. To relieve the stress of long-distance transportation on the chicks, add 3% white sugar and electrolytic cubes to the drinking water, but the drinking time should not be too long. , Generally about 6 hours, the time will appear too long paste anal phenomenon. After the chicks enter the house, the weak chicks that do not drink water will be singled out and taken care of. This will greatly help improve the survival rate of broodstock. After 7-10 days of age, it can be transferred to the automatic drinking water system. It must be determined that the chick has learned to use the new drinking water equipment before it can be removed. Lighting management: The first three days of brooding, 24 hours of light, the light is getting brighter and better, so that the chicks can adapt to the new environment as soon as possible. Changed to 22 hours on the fourth day, the light intensity can be reduced to 20 luxes, it can be reduced to 20 hours after one week and 18 hours from the second week. This declining light program is used during the brooding period in order to have more time for drinking water in order to reach the target weight early and establish a good body shape. Defective Management: Due to the small body weight and slow growth of Roman egg breeders, we generally require 7-10 days of age for correct deafness, which is less stressful for chicks. Pay attention to the fact that professional technicians must operate during the break to ensure quality. After 3-5 days after the larvae were cut off, the brooding temperature was appropriately increased, and the amount of feed was increased. Two days before and after the break, VK was added to the drinking water to heal the burns as soon as possible. Pay attention to the prevention of coccidiosis and chronic respiratory diseases: prevention of coccidiosis, raising broods generally use 3 days of coccidiosis vaccine spray immunization, but should pay attention to immunization should strengthen the litter management of chicken coops, timely expansion of the column , Reduce the density of chickens, diligent in observation of feces, understanding of the development of coccidial oocysts, in order to promptly carry out drug prevention of aminopropriod, to ensure the success of immunization. In short, whether the chickens can grow and develop as required before 5 weeks of age is the key to the profitability of the entire batch of chickens.
