Key points of breeding commercial broilers with density and temperature feed feeding method

For commercial broilers, chicken preparation is very important, and full-in-all-out mode should be considered. When the broilers are out of the pen, the henhouse should be disinfected and the residual feces should be removed in time. After cleaning the chicken house, spray 2 times with 3% sodium hydroxide solution and 0.4% 0.5% potent solution. After disinfection, the chicken house was treated with empty house for more than a week. If the air circulation is poor, it can be extended appropriately; if there are residual feces and chicken feathers around the chicken house, it should also be cleaned in time and disinfected with lime powder after cleaning. Two days before entering the chicken, raise the temperature of the chicken house to about 33 ℃ to ensure the temperature of the brooding room.

Main points of feeding:

Control the feeding density. Most commercial broilers are raised on the Internet, and some are kept free on the ground. When entering the nursery, the density of chicks must be strictly controlled. Excessive density is easy to cause extrusion, uneven feeding, affecting the growth of chicks; too small density, waste of facilities, not conducive to heat preservation. Chicken farmers should control the density according to the breeding space.

Temperature and humidity control. The temperature and humidity of chicken house also have a great influence on the growth rate of commercial broilers. In the process of chicken growth, it is necessary to strengthen ventilation and control temperature and humidity. If the temperature is suitable, the chicks sleep quietly, evenly distributed and have a good appetite; if the temperature is low, they scream; if the temperature is high, they drink frequently. Chicken house temperature and ventilation interact and influence each other, so ventilation is very important. When the weather is fine at noon every day in winter, the chicken house will be ventilated for 10-20 minutes to ensure that the temperature of the chicken house will not be affected, and when it is hot in summer, the ventilation time will be increased. The relative humidity of the brooding room is high before and then low, and it is more appropriate to use 60%-70% in the early stage; after 10 days of age, the relative humidity is kept at 50%-60%, and the humidity is too high, which is easy to cause coccidiosis.

Feed as soon as possible. The growth rate of commercial broilers is fast. In order to improve the digestive organs and immune system of chicks as soon as possible, chicks should eat as soon as possible and obtain nutrition through the feed in the digestive tract. After coming out of the shell, the chickens need to have an adaptive process to obtain nutrients in the feed. There are still 40.7 grams of egg yolk in the chicks after coming out of the shell, which is the only nutritional supplement before eating and before adapting to the digestive tract. However, the time for egg yolk to provide nutrition is limited, if the chicks can not adapt to the nutrition in the feed as soon as possible, it will affect the future growth. Therefore, when the chicks enter the nursery, they should be fed and drunk in time.

Feed feeding method. The nutritional composition and particle size of feed for commercial broilers are different in different stages. As a commercial broiler, the maladaptation in the process of changing feed is very obvious, indigestion, green in chicken feces, serious, it will cause feed waste and disease. Therefore, the feed should be changed gradually so that the chicks have the process of adaptation. If the disease is caused by negligence, it is necessary to timely feed Jianwei Xiaoshi Powder and Pingwei Powder and other drugs to avoid unnecessary stress.
