Winter Broiler Breeding Notes
First, heat and cold, can not forget the ventilation In winter, the climate is cold, and the temperature required inside the home is very different from the outside air temperature. It is necessary to ventilate the air and keep the temperature inside. The chicken house requires good cold resistance and meets the winter insulation requirements. Prevention of chilling caused by chilling caused by chicks. While ventilating and ventilating, be careful not to cause the temperature in the house to be ups and downs, and to prevent the stress caused by the excessive temperature difference from causing the disease. It is advisable to use the ventilation outlet more than 1.5 meters above the back of the chicken. When the temperature drops sharply and the cold and heat insulation work cannot keep up, it is easy to make the broiler exogenously cold and develop respiratory diseases characterized by cough, sneezing, tracheal rales, and dyspnea. Therefore, the breeder must master the changes in the climate and do a good job in cold insulation. The hen house should be maintained to prevent thieves and drafts from invading the flock. The broilers raised on the plains must be thickened with litter and use litter to increase the room temperature. Always change the litter, open the window ventilation at noon. In general, ventilation is started at 6 days of age, and as the age increases, ventilation is increased so that the birds have enough oxygen. Second, keep dry and do not forget to drain ammonia In winter, the climate is cold. It is not possible to neglect the ventilation and ventilation in order to keep the chicken house warm. The excrement of feces and damp litter from the chickens is not cleared in time, resulting in the accumulation of ammonia gas in the house and the increase in the concentration, resulting in broiler ammonia poisoning or Cause other diseases. In order to prevent the adverse effects of ammonia on broilers, it is recommended that the chicken farm (household) do a good job of the following feeding and management work: minimize watering during operation to prevent the water tank from leaking; if the humidity in the house is too high, the house waste should be promptly removed. And damp litter. In addition, ammonia absorption and deodorizing agent can be used to reduce the ammonia concentration of the house. Commonly used are ferrous sulfate, superphosphoric acid, copper sulfate, hydrated lime and the like. Third, strengthen feeding, can not forget to prevent disease According to the different growth stages of broilers, diets are formulated according to feeding standards. Due to the low temperature in winter, the calories consumed by broilers are relatively large. When formulating diets, the standard of metabolic energy in feeds can be appropriately increased, and the proportion of protein in feeds should be properly reduced. At the same time, special attention should be paid to the vitamin content in diets to meet their needs. . The raw grain of the formulated feed must be free of mildew and impurities to prevent respiratory diseases. In order to prevent viral diseases and bacterial diseases, when broilers have weak physique and decreased resistance, some diseases can also induce respiratory diseases. Therefore, while improving the body's resistance, we must do a good job in the prevention and control of diseases. Vaccination against vaccination must be conducted in strict accordance with immunization procedures. Regularly use some medicines to prevent diseases and regularly disinfect the sheds. Fourth, strengthen management, can not forget the routine Before hatching, youngsters shall be scoured, sterilized, fumigated, and utensils, clothes and hats, and premises thoroughly cleaned. To control drinking water, drinking water is generally 2-3 times the amount of material consumed, but it is not appropriate to provide more water, because the water will increase the humidity of the litter and prevent running water when using a water pipe. Broiler flocks are prone to non-infectious respiratory diseases, especially when broilers of about 25 days of age are prone to develop in the winter. The disease is the result of poor husbandry and management. It is mainly due to air drying and excessive dust in the house. In case of poor ventilation, the disease is inhaled and accumulated for a long time. Prevention and control measures are to maintain the temperature within the premises, increase ventilation, in order to guarantee the oxygen content in the house, is the chicken is not the incidence or the incidence of disease, as soon as possible after the onset of the basic conditions for recovery. Fifth, environmental control, can not forget health First of all, chickens should be introduced from healthy chicken farms to prevent vertical transmission of pathogens. Second, we should create a good breeding environment. Keeping utensils and sterilizers are strictly differentiated and regularly sterilized to prevent horizontal transmission of diseases. At the same time, the occurrence of disease outbreaks in neighboring chicken farms and in the area are regularly monitored and preventive measures are taken. Regularly monitor the health condition of the flocks in this farm and handle the epidemic in time. Third, adhere to the principle of sterilizing chickens, eradicating rodents, preventing rodent-transmitted diseases, burying dead chickens, and isolating chickens from healthy chickens.
