With the development of the breeding industry, the broiler cages are also increasing, but the problems encountered in the cage raising process are also more and more. The following are the management points of caged broilers.
First, grouping
Three-dimensional cultured broiler chickens use the whole sports chicks. When the chicks are too dense, they should be grouped in time to ensure that the chicks have uniform body weight. In summer, due to high temperature, they can be properly caged in advance. In winter, due to the large temperature difference between the upper and lower layers of the cage, the cage time can be appropriately postponed. Place one more in the lower cage to reduce the temperature difference between the upper and lower layers.
Second, disinfection
The chicks are thoroughly cleaned and disinfected 5 days before entering the site to avoid corrosive disinfectant, prevent equipment damage, seal the doors and windows, and open the window after 24 hours. At this time, the personnel entering and leaving the house must be strictly disinfected to avoid destroying the disinfection effect. Cleaning and disinfecting the trough and drinking fountain. After the chicks arrive, clean the ground every day to reduce the stimulation of the respiratory tract by dust and chicken fluff. After every other day, the whole site should be disinfected with chicken. Several disinfectants can be used alternately to disinfect. Avoid vaccination for more than 24 hours.
Third, the temperature
There is a temperature difference between the three-layer chicken cages in the upper, middle and lower layers, and the lower the outdoor temperature, the greater the temperature difference. Brooding is generally at the highest level, because the highest temperature is the highest, which is conducive to saving heat. The chicks enter the field on the first day, the temperature is controlled at 33 ~ 34 ° C, but also according to the state of the chicks to adjust the temperature. When the temperature is suitable, the flocks are evenly distributed, lively and active, and have a strong appetite; when the temperature is low, concentrate on the heat source. Squeeze each other, the body trembles; when the temperature is too high, the amount of water increases, the appetite decreases, the breathing speeds up, and the neck feathers are soaked. In the first week, the temperature dropped to 30~C, and then decreased by 2°C every week. The density of three-dimensional culture was large, which was 1~2~C lower than the flattening temperature. It should avoid the heat stress and the food intake decreased.
Fourth, ventilation
The key to successful aquaculture is ventilation, reasonable ventilation, elimination of harmful gases, temperature control, and disease occurrence. Therefore, ventilation is very important. Adjust the position and size of the air inlet, day, night, cloudy, sunny, spring, summer, autumn and winter. It is necessary to constantly adjust and adjust to the air in the house without odor, glare, no oxygen deficiency, more comfortable feeling, create a good growth space for the chicken, enhance the body’s disease resistance and reduce the occurrence of the disease.
Fifth. Stereo aquaculture chicken house adopts artificial illumination to control the illumination time. Seven days before brooding, 24 hours of light is used, and then 22 hours later. The purpose is to let the chicks get used to the dark environment and not cause panic caused by sudden blackout. Squeeze casualties, and then gradually increase to 24 hours of light a week before going out.
Sixth. Drinking water and feeding. After the chicks enter the chicken house, they should be fed with boiling water. After feeding the water, feed the water for 2 to 3 hours, then put the feed into the opening tray for the chicks to forage in automatic poultry farming .
