Effect of Air flow on Pig growth
The effect of air flow on pig body is mainly to affect the heat dissipation of pig body. Under general environmental conditions, as long as there is air flow, it can promote the convection and evaporation heat dissipation of the body. When the ambient temperature is lower than the suitable temperature limit of the pig, the heat dissipation of the pig is increased due to the action of air flow, which makes the pig feel cold. at this time, more energy is needed to maintain the body temperature. On the contrary, when the ambient temperature is higher than the upper limit of the suitable temperature for pigs, because the air flow contributes to the heat dissipation of pigs, and when the air flow is large, the heat dissipation is more, so the wind speed is increased.

Effect of airflow on pigs
The motion of air molecules is called air flow, and the air flow that moves horizontally is called wind. The air flow in the atmosphere is caused by the uneven temperature distribution on the earth's surface, and the air molecules flow from the region of low temperature and high pressure to the region of high temperature and low pressure. In weather, the wind speed and direction are often described. The wind speed is the distance of the wind movement per unit time (m); the wind direction is the direction of the wind, expressed in 8 or 16 directions, and the wind direction frequency chart (wind direction rose chart) is drawn according to the probability of the wind appearing in each direction.
