The chicks hatched by the spring chicks from March to April each year are spring chicks. During this period, the climate in the north gradually warms up, which is very beneficial to the growth of chicks, and the survival rate of brooders is high. The new chickens were put into production in August-September of the same year. This is the season in which the eggs were laid down by the old chickens. This can make up for the shortage of fresh eggs in the off-season market, and the egg production period can be continued until the end of the second year of the fall. Higher economic efficiency.
In late spring, the chicks hatched in late April-May each year are late spring chicks. At this time, the climate is warmer, the management is easier, the insulation cost is reduced, and the survival rate of brooding is higher. The new chicken was opened in the late fall and early winter of the year, and the peak price was higher before the Spring Festival. The price of eggs was higher and better economic returns were achieved.
High-temperature brooding Because the yolk is not absorbed well after the hatching of the chicks, the physique is weak and the resistance is poor. The use of high-temperature brooding can promote the absorption of yolk and reduce the mortality rate. 35-36°C in the first week and 2°C lower each week.
Maintaining a certain humidity Due to the high temperature during the brooding period, the humidity in the house is low, and it is easy to dry, causing dust to fly, and easily causing foreign body bronchitis. Therefore, we should regularly increase the humidity, can be sterilized with chicken spray, can also put an iron pot on the stove, regular chlorine disinfectant, to achieve disinfection and increase the humidity for two purposes. Humidity during the brooding period is 65-70%.
The purpose of deterrence and deterrence is to prevent the occurrence of delirium, which is usually the first time in the 6-10 days, the second time in the 14-16 weeks of age, with a special tool to cut off the upper 1/2-2/3, Squat off 1/3. Some fish farmers are afraid of the occurrence of paralysis. Once they are cut off too much, they become sarcomas, severely affecting feeding and growth, and others are reluctant to break. Occurrences occur when laying eggs.
Ventilation is mainly 1-2 weeks, but don't forget to ventilate. The amount of ventilation should be increased in the 3rd week. With the acceleration of chicken growth speed in the later period of feeding, chickens need to have relatively increased oxygen. Ventilation and ventilation of dragons at this stage are important. In the spring, the ventilation should be performed at the same time as the insulation to reduce the concentration of harmful gases such as dust, carbon dioxide, and ammonia, reduce the humidity in the house, and keep the air fresh, so as to reduce the occurrence of respiratory and intestinal diseases.
Diseases prone to brooding diseases include chicken psoriasis, omphalitis, enteritis, bursal disease, and coccidiosis. Drugs should be regularly administered and vaccination work should be done at the same time.
