Commercial broiler chicken breeding technology
Commercial broilers have the characteristics of short feeding cycle and fast growing speed. The key to raising good broiler chickens lies in feeding management and environmental control. In the breeding process, we must pay attention to meticulous operations, and do a good job of disinfection of all facilities in the chicken house. Using a scientific feeding management model, the best breeding advantages can be achieved.
Prepare for chicken
For commercial broilers, preparations before entering the chicken are very important. The best way to raise should consider all-in and all-out modes. Whenever a batch of broilers are slaughtered, the chicken house must be completely disinfected to remove the remaining feces in time. After cleaning the chicken house, 3% sodium hydroxide solution and 0.4% to 0.5% of the power-kill solution can be sprayed and disinfected 2 to 3 times. After the disinfection, the house should be left empty and the empty time should be more than one week. If the air circulation is poor, the time for emptying can be appropriately extended. If there are residual feces and chicken feathers around the house, clean it in time and clean it before disinfecting it with lime powder. Two days before entering the chicken, the temperature inside the henhouse should be raised to about 33°C, mainly to ensure the temperature of the brooding room.
Feeding points
Control breeding density. In most regions, broiler chickens are raised on the Internet, while some are on the ground. However, the hatching density of chicks must be strictly controlled when entering the brooding room. If the density is too large, extrusion is likely to occur, and feeding is uneven, which affects the growth and development of the chicks. If the density is too small, the facility is wasted, and it is also not conducive to heat preservation. Farmers need to control the density according to the breeding space, because controlling the breeding density is an essential means to increase the healthy growth of commercial broilers.
Temperature and humidity control. The temperature and humidity of the broiler house also have a great influence on the growth rate of commercial broilers. During the whole growth process of chickens, it is necessary to strengthen the ventilation and strictly control the temperature and humidity. If the temperature is appropriate, the chicks sleep quietly, evenly distributed, and have good appetite. The temperature is low and the crowd screams. When the temperature is high, the chicks frequently drink water. The temperature and ventilation of the chicken house are originally interacting and affecting each other. Ventilation is very critical during the breeding process. According to the author's breeding experience, it is recommended that the house be ventilated in fine weather at noon every winter to guarantee the house's The temperature is not affected. Generally, the ventilation time should be maintained between 10 minutes and 20 minutes. During the summer, the ventilation time needs to be increased. The relative humidity in the brooding room is high before and low, and it is suitable for 60%~70% in the early stage; it is maintained at 50%~60% after 10 days of age, and excessive humidity can easily cause coccidiosis.
Feed as early as possible. Commercial broilers grow fast. In order to develop the digestive organs of the chicks, the immune system should be improved as soon as possible. The chicks should be allowed to eat as soon as possible and obtain nutrition through the feed in the digestive tract. After hatching, the chicks need to adapt to the nutrition in the feed. There are 4 to 7 grams of egg yolk remaining in the body of the chicks after hatching. Their role is to serve as the only nutritional supplement before eating and before adapting to the digestive tract. However, the time to provide nutrition is limited, if the chick can not adapt to the nutrition contained in the feed in the shortest time, will inevitably affect the future growth. Therefore, when the chicks enter the brooding room, they should be fed in time to drink water in time.
Feed feeding method. Different broiler chickens need different feeds for different stages of development, and the nutrients and particle size requirements in the feed are different. As a commodity broiler, the incompatibility exhibited in the process of changing the feed is very obvious, and indigestion or the like may occur, or the stool may be green, and in serious cases, it may also result in waste of feed and cause disease. Therefore, great care must be taken when changing the feed. The feed should be changed gradually so that the chicks have an adaptive process. If negligence can easily lead to symptoms, timely control of drugs such as Jianweixiaoshisan and Pingweisan should be conducted to avoid unnecessary stress.
