In the autumn and winter, the external temperature gradually turns from warm to cold, the temperature difference between day and night is large, the air is dry, and respiratory diseases are more frequent. Therefore, the demonstration households should master the following points in the feeding management of broilers in autumn and winter.
1. Do a good job in the maintenance of the chicken house. After the autumn, the weather will become cold. The maintenance of the house should be done in advance. Check whether the house is leaking, leaking, whether the doors and windows are sealed, heating facilities, ventilation equipment, etc. .
2. Do a good job of disinfection. The main thing is to disinfect the inside and outside of the house and the utensils, as well as disinfection of drinking water. In the disinfection of chicken with disinfectant, special attention should be paid to the use of disinfectant drugs that are not irritating to chickens. The external environment of the house should be disinfected at least once a week to kill the pathogens outside the body. The utensils should be cleaned before disinfection. The corrosive disinfectant can be soaked for about 1 hour and then dried. Regularly add disinfectant to the drinking water for the chicken to increase the ability of the chicken to resist disease.
Note: Pay attention to the protection and cleaning of the chicken battery cages to avoid bacterial growth and virus infection.
3. Do a good job of ventilation. In autumn and winter, the contradiction between heat preservation and ventilation should be properly handled. When opening the air, do not open the doors and windows or the ventilation equipment for a long time to prevent the chicken from getting cold. When the weather is cold, the air window can be opened smaller. When the air is warmer, the air window will be larger, the leeward side can be opened larger, and the night will be smaller and open during the day. Pipes are used for ventilation when heating in a coal stove to prevent carbon monoxide poisoning.
