The epidemic prevention and transfer in production can all cause pig stress. Therefore, each time you take any action that will cause stress in your pigs, consider using a method that can reduce stress to complete the job.
Most pigs develop pneumonia in bad air conditions. Pigs raised outdoors rarely develop pneumonia, because a large amount of fresh air plays a role. Since the size and feeding density of each pig house are different, the type of air flow required is different. Do a good job of ventilation so that fans and vents can be controlled at will. We must do everything possible to prevent the thief, because the thief is more likely to cause stress. In addition to considering the ventilation of the entire building, the local wind strength must be considered. High-speed local air flow can cause pigs to feel cold and cause stress. The standard is that the wind speed at the level of the pig should not exceed 0.3 meters per second. If the position of the air inlet is improper, the door is not closed, the doors and windows are broken, or there is a hole in the wall and the curtain, and the wind speed will increase, so that the pig will develop respiratory diseases. Even in the hottest weather, wind speed must be controlled.
Under ideal temperature conditions, pigs feel comfortable at any time. Both heat and cold can cause stress, reduce the immunity of the pig and increase the chance of attack. New weaning pig houses should be guaranteed to be warm enough. If necessary, the pighouse should be warmed up 24 hours to 49 hours before entering the pig. The demand of pigs for temperature decreases with age, and farmers need to formulate plans or measures for gradual cooling, and they must implement strict regulations.
Pigs also have certain requirements on the humidity in the house. Relative humidity below 50% is too dry and 75% is too wet. If the humidity in the house is too low, pigs can easily cause respiratory diseases. The thermal conductivity of moist air is 10 times that of dry air. If the humidity in the house is too high in winter, the amount of heat emitted by the pig will increase, making the pigs more cold. If the humidity in the summer is too high, the pig will breathe when breathing. The moisture released into the air is limited.
Pigs are contaminated, germs multiply, and they can easily cause various diseases, increase the cost of raising pigs, and reduce pig-raising efficiency. In the production, it is possible to reduce the humidity in the house by means of enhanced ventilation and the placement of quicklime blocks in the room.
Whether the breeding density is reasonable is not only related to the pig's development status, but also has a close relationship with the pig's pneumonia; the density varies according to the climate, the summer should be as small as possible, and the winter can be slightly larger, but there should be a total area in each shed. 2/3 dry ground is used for lying and resting pigs. Whether on the concrete floor or bare ground, the sleeping area must be kept clean, dry and comfortable, thereby reducing the pig's stress. It is critical to reduce the rearing density of weaned pigs. The experts recommended the following stocking densities: weaned pigs: 3 heads per square meter, growing/finishing pigs: 0.75 square meters per head.
Drinking water disinfection can reduce the stress caused by pathogens in pigs, reduce the incidence of pigs, and improve the health of pigs. It is best to use groundwater or water that does not contain harmful substances and microorganisms, and at the same time pay attention to the supply of clean drinking water at all times to meet the needs of pigs.
Pig feed intake decreased at high temperatures, resulting in insufficient energy supply. In order to relieve the pigs from the effects of high temperature environment, pigs should generally be given higher nutrient-concentration diets in the hot season to compensate for the lack of energy intake due to high temperatures.
