(a) repair and reinforce the chicken house. For the timely repair and repair of broiler houses damaged by the disaster, check the maintenance circuit, prevent the damage of the wires, dig and reinforce the drainage ditch around the house, and choose a flat or slightly sloped area on the south side, away from the traffic arteries and Residential area.
(b) choose good breeds. According to the local production conditions and market demand, from the breeder farms with complete licenses, high production management levels, and good after-sales service, the varieties were introduced, and the stocks were timely restocked to restore the poultry production capacity.
(c) Strengthen biosecurity measures. Timely immunization, close monitoring of antibody levels and flock dynamics, effective prevention of infectious bronchitis, bird flu, Newcastle disease, laryngotracheitis and other diseases. Dispose of the injured chickens in time. Dead chickens can be treated in a timely manner by sprinkling lime pits or incinerating them to prevent the spread of disease.
(D) timely adjustment of ration composition. Because of the typhoon, the temperatures decrease, and the basal metabolism of chickens increases greatly. For broiler breeders and broilers not reaching the market age, their dietary energy concentration should be increased and the amount of feeds should be increased. For example, corn can be increased by 10%-20% and maize is in short supply. Areas can be temporarily replaced with rice. For those who have reached the age of listed broilers but the traffic is still poor, dietary nutrient concentrations should be appropriately adjusted to meet the basic purpose of basal metabolism and to minimize losses. 100-200g of vitamin C supplemented per ton of feed and 200-500g/ton of feed complex enzyme preparation. Vitamin C supplementation can improve the disease resistance and survival rate of chickens under low temperature stress conditions. The addition of compound enzyme preparations can improve the utilization of non-starch polysaccharide components in feeds and improve energy efficiency. Drinking water or feed supplement multidimensional, electrolyte and other health, anti-stress drugs. Strengthen feeding management. Strengthen the insulation measures, especially the local insulation, to prevent the chickens from crushed; the chicks need to increase the heat lamps; minimize the outdoor exercise of the broiler chickens; strengthen the sealing measures of the chickens, and pay attention to adequate ventilation and fire safety. If chickens are found to be crowded, crowded, or trembled, the ambient temperature is too low, try to increase the temperature inside the house, and lay dry bedding in the house (thickness of 5cm or more), especially to keep The litter is dry. In the low-temperature environment of typhoon storms, the doors and windows of chicken coops and curtains are tightly closed and the air circulation is poor. However, ammonia, carbon dioxide, hydrogen sulfide, and other gases produced during the fermentation of chicken exhaust gas and chicken excrement are easily induced in the respiratory tract of chickens. disease. Therefore, it is necessary to regularly or when the weather is good at noon, open the window or roller blind for ventilation, timely removal of manure and debris in the chicken house, and effectively handle the relationship between the ventilation and warmth of the chicken house. Pay attention to ventilation and keep the air fresh.
