Technical points of raising broilers in net frame

1. The construction of chicken coop. The chicken house had better be located far away from the village, with slightly higher terrain and good ventilation. No matter the asbestos house or bungalow is built, the house should not be too low. The house that is too low is poor in thermal insulation in winter and poor in summer. The roof is equipped with skylights, the wall root leaves vents, the doors and windows should not be too small, and the span of the house had better be more than 5 meters.

2. Heating. Temperature is the key to improve the survival rate of broilers. After the chicken coop is built, the heating equipment had better use the floor Kang. The fire of the Kang should be built near the gable on one side of the door. after entering the house, the fire dragon is divided into left and right forks, converge to the other side of the gable and discharge from the chimney outside the wall. The distance between the fire dragon and the walls on the left and right sides is about 0.75 to 1.50 meters.

3. The construction of the grid. Chicken nets are generally built from the ground about 1 to 1.2 meters, on both sides of the house, directly above the fire dragon, leaving a corridor of about 0.5 meters and 0.75 meters in the middle, in order to clean up dung, add food and water, and so on. The shelf is made of bamboo poles or sticks with a diameter of 2 to 2.5 cm, which is suitable to withstand the weight of adult chickens.

4. Preparation before entering the baby. To build a new chicken house, you only need to spray it once with disinfectant. For example, spray with Baidu, Disinfection King and so on. If it is an old chicken coop, scrub the equipment carefully before spraying with 2%NaOH solution. Then, fumigate with potassium permanganate and formaldehyde, and finally use Baidu spray. After all the disinfection was completed, the preheating of ignition was started, and the temperature in the range of brooding reached 32-35 ℃. The warm-up time depends on the season and the outside temperature. Generally preheat 2-3 days in winter, 2 days in spring and autumn, and 1 day in summer. Check the thermometer at any time to see if the temperature meets the requirements. Preheating the stove should prevent gas poisoning.

5. Management after brooding. After entering the chick, you should first give the chicken drinking water, and add electrolytic multi-dimensional and glucose to the drinking water to reduce the stress during transportation. The best standard for the temperature after brooding is that the chickens feel comfortable. If the flock is far away from the heat source and has the phenomenon of breathing with open mouth, it indicates that the temperature is on the high side. If the flock is close to the heat source and crowded together, it indicates that the temperature is on the low side. The chickens lying evenly on the edge of the heat source indicate that the temperature is moderate. Generally, the temperature in the previous week was 32-35 ℃, then decreased by about 3 ℃ per week, and finally 21 ℃ was more suitable. Broilers in the suitable temperature range, the ideal humidity is about 40-72%, the humidity is too high, it will cause a variety of diseases such as coccidiosis, the humidity is too low, the dust in the air is increased, and respiratory diseases are easy to occur. Broilers generally use 24-hour light, if given one hour of dark time every day, the chicken can adapt to the dark environment, once the power outage, will not be crowded and suffocated. The principle of light intensity of broilers is from strong to weak, and there should be 2.7 watts of light per square meter in 1 week or 2 weeks. This can help chicks familiarize themselves with the environment and fully eat and drink water. At the beginning of the third week, it was changed to 0.7 to 1.3 watts per square meter. Strong light is harmful to chickens and hinders their growth. Weak light can quiet chickens and help them grow and fatten. Fresh air and proper ventilation in the chicken house are prerequisites for raising broilers. Enough oxygen can keep the chickens in good health. In general, the oxygen content of the chicken house should be kept above 18%. To avoid excessive ammonia, inhaling too much ammonia will stimulate the trachea, cause tracheitis, conjunctivitis, ascites, etc., and increase the chance of infection of coccidiosis, thus reducing the conversion rate of feed. causing slow growth. Regular epidemic prevention can effectively prevent the occurrence of infectious diseases. For example, chicken Newcastle disease, infectious bursa of Fabricius, bronchitis and so on, broilers generally use 4 times vaccine. H120 was used for nasal dripping in the first week, Fabricius vaccine in the second week, H52 in the third week, and Fabricius vaccine again in the fourth week. Observe the chicken flock, you can know the health status of the chicken flock at any time. Healthy chickens have a good spirit, quick response, exuberant appetite, unhealthy chickens are in low spirits, slow to move, shrink their necks and close their eyes, slow to respond, stand apart from the group, droop wings, and have poor spirits. Under normal circumstances, feces have a certain shape, showing grayish brown, with a certain amount of white substance on the surface. If the stool is abnormal, it means that the disease has been infected, it is necessary to make timely diagnosis and treatment, so as not to cause economic losses.
