1, chicken feeding management
(1) Preparation before brooding
A. Preparation of brooding room: choose heat preservation and heating mode, build brooding facilities and heat preservation facilities, and spread sterilized bedding (chaff and chopped straw) on the flat ground.
B. Preheating and temperature test before chicks are transported: debug the heat preservation facilities to make the temperature of the brooding room meet the requirements, and transport chicks only after reaching the specified temperature.
C, prepare enough feed and drinking fountains (every 100 chickens 1 feed trough and drinking fountains).
D disinfection: see the technical specification for epidemic prevention for disinfection methods of brooding rooms and utensils.
E, rainy season and cold should prepare rain-proof and cold-proof equipment to prevent chicks from getting wet and blowing.
F, selecting healthy chickens and eliminating sick chickens and weak chickens.
(2) Feeding and management of chicks
Usually 0-6 weeks old is the chick stage, which is called the brooding period.
(1) temperature management: temperature is the first condition for brooding. Even in summer, it is necessary to keep warm because of the large temperature difference between day and night. The quality of heat preservation is the key to the success of brooding, because newborn chicks have poor temperature regulation ability and are particularly sensitive to temperature changes. If the temperature of brooding is too low, the chicks will gather, scream, close their eyes and tremble because they are afraid of the cold, which will affect their eating and exercise. In severe cases, they will squeeze each other to death, and some will catch a cold, diarrhea or even die. Excessive temperature will affect normal metabolism, loss of appetite, increased drinking water, weak body, slow development, and prone to respiratory diseases and pecking addiction. When the temperature is suitable, the chickens are lively, energetic and quiet, and evenly distributed in the brooding room. So the temperature must be controlled. The general brooding temperature is 65438+35-36℃, 0-2 days, 35-32℃, 3-7 days, 32-28℃ in the second week, 29-27℃ in the third week and 27-25℃ in the fourth week. After one month, the temperature was removed and the room temperature was kept at about 22℃. The thermometer for measuring temperature should be hung at the same height as the chicken's back.
(2) Temperature management: The water content of chicks in the same shell is above 70%. The growth and development of chicks need suitable humidity. When the humidity is too low, the chicks lose too much water, the yolk in the abdomen is poorly absorbed, the fluff is dry and fragile, and the chicks are prone to respiratory diseases. The humidity can be adjusted by the steam emitted by indoor boiling water. Excessive humidity is conducive to the reproduction of germs and eggs, and chicks are prone to gastrointestinal diseases, aspergillosis, coccidiosis and so on. Therefore, we should pay attention to ventilation, change the padding frequently and prevent water leakage. In summer, the temperature is high and the humidity is high, so the heat in chicks is not easy to dissipate, which is characterized by decreased appetite and slow growth. Therefore, measures should be taken to reduce the temperature and pay attention to ventilation, ventilation or density reduction. Humidity can be measured by a dry hygrometer. The suitable relative humidity in the brooding room is 65-70% at 0-2 weeks old and 55-60% after 3 weeks old.
(3) Density: The density of chickens directly affects the feeding, activities, drinking water, growth and health of chickens. Too high density, wet padding, air pollution, poor feather growth, prone to pecking and parasitic diseases, high morbidity and mortality. The density is too small, the utilization rate of chicken house is low and the cost is high. Therefore, the proper density should be arranged according to the area of henhouse, the season and scale of brooding, the age of chicks and other factors. Usually 1-7 years old has 50 animals per square meter, 8- 14 years old has 35-40 animals per square meter, and 15-28 years old has 25 animals per square meter. From now on, according to the size of the chicken, it is 8-65438 per square meter.
