The temperature required for the pigs at each stage is different, which requires the production manager to keep abreast of the temperature and control the temperature so as to minimize the stress caused by improper temperature and the impact on production. The temperature is summarized as follows:
Optimum temperature range for boars: 17-21°C; optimum temperature range for pregnant sows: 18-21°C; optimum temperature for sows: 20-22°C; optimum temperature for suckling piglets: 29- 33°C; optimal temperature for nursery piglets: 22-25°C; optimum temperature for finishing pigs: 19-22°C.
Combining with actual production conditions, how to grasp the temperature of different herds is the key. From a production manager's point of view, managers should be aware of the temperature range required by the herd at each stage, and think of ways to provide operable conditions, such as summer ventilation, cooling equipment, winter heating, heating equipment, and require rearing. The staff can register the temperature of the pig house and pig herd each day, and keep records of archival records. From the point of view of the breeder, it is necessary to control the temperature of her own herd, which is the most critical factor in raising pigs. How to effectively control the temperature of the herd is as follows:
(1) Keep the manure as dry as possible, avoid using water as much as possible without water, and prevent the stress of high temperature, high humidity and low temperature and high humidity on the pigs; (2) observe the specific conditions of the herd, such as sleeping position and feed intake; (3) do a good job Ventilation, warming and other work; (4) to prevent the thieves wind and summer heat.
The thermometer is an important basis for measuring the temperature in the livestock house. However, we cannot rely too much on the thermometer. We must be pig-oriented and the pigs have the final say. This requires the breeder to have a high degree of responsibility and dedication. If the temperature of the delivery room is 21-25°C, and the temperature of the incubator is 29-32°C, the breeder can't just look at the thermometer within this range and everything will be fine. He must carefully observe the sleeping position and sow of the sow and suckling pig. Food, health and other conditions to adjust the temperature, so that the pigs in the most appropriate state. After weaning piglets, usually need to warm up, the range is 29-31 °C, but in our actual operation, we can not just look at the thermometer is this range on the line, need to observe the pig's sleeping position and feed intake, the temperature is high, the piglets do not feed Drink plenty of water, sleep dispersedly or do not sleep. The temperature was low and the piglets huddled together. The keeper should adjust the temperature in time according to these conditions to ensure the optimum temperature of the piglet.
Temperature is the basic guarantee for the health of pigs and it is one of the important factors that can build internal immunity of pigs. At the same time, temperature is also the best barrier to control pathogens. Therefore, grasping the temperature of pigs is the magic weapon for winning pigs.
