Increase the amount of sunstroke-preventing cooling facilities 1. Within 3-5 meters from the house, use tall evergreen trees for greening, use outer trees for evergreen shrubs, shade and regulate air, and 2 use foam or straw as the roof of the house. Insulation, the roof can be painted white with polyvinyl chloride paint to reduce solar radiation. 3. Longitudinal ventilation is used in the house. 4, design curtain cooling facilities. Install the curtain at the air inlet. Use it at high temperatures from 8am to 6pm daily. 5. Install high-pressure fog rotating sprinkler on the roof. At high temperatures, spray every 2-3 hours.
Strengthen day-to-day management to reduce the amount of chicken per unit area, raise 5-6 eggs per square meter on the ground, raise 6-7 eggs per square meter on the Internet, ensure sufficient cool drinking water, increase the number of drinking troughs, and ensure that every chicken can Drink water in a timely manner; keep the litter dry. Reduce the release of harmful gases such as ammonia and use absorbent material (such as sawdust, chaff, etc.). A certain amount of superphosphate is added to the litter to absorb harmful gases such as ammonia and hydrogen sulfide.
Adjust the diet formula to reduce the amount of metabolic energy in the feed, change the animal protein to vegetable protein, do not add fat-based feed ingredients, and reduce the energy-protein ratio in the feed. In the feed properly increase the content of multivitamins, if conditions are available, try to use some melon peel and vegetable or multi-leaf forage green feed during the day.
In the proper selection of additives for raising chickens, nicarbazin (coccidial or net) is commonly used to prevent multiple coccidiosis. However, because it can aggravate the heat stress response, it cannot be used to prevent coccidiosis in the summer. Adding 0.5% sodium bicarbonate and 1% ammonium chloride to the diet can reduce the occurrence of heat stress syndrome. Adding 200 mg of vitamin C and 50 mg of potassium chloride per kilogram of feed can also reduce chicken mortality.
The prevention of disease prevention work must not be taken lightly: 1. It is necessary to do a good job of vaccination in a timely and correct manner. 2. Do a good job of disinfecting the venues and utensils, and clean the drinking water, food troughs, cleaning tools, etc. in a timely manner so that it can be cleaned once every two days. The site is sprayed with a non-corrosive broad-spectrum disinfectant spray once every 2-3 days. 3, reduce the breeding of mosquitoes and flies, to maintain environmental hygiene, chicken manure to be timely fermentation, sewage should be promptly discharged. 4. Disinfecting chickens with highly effective and low-toxic drugs can, on one hand, reduce the number of germs in the environment, and on the other hand, can reduce the temperature in the small environment. 5, to do a good job in the deep-buried work of dead chickens, to reduce the environmental pollution of pathogens, to prevent the presence or reproduction of pathogens in the small environment.
