As the transportation route becomes longer, the adverse effects of hot and humid environment will become more and more serious during the vehicle-mounted process. In livestock transportation, mortality has always been a worrying problem. As long as the country produces edible poultry, there will be such episodes (occasional deaths). Therefore, Warriss et al. 2005 (an article published by Warriss in 2005) described that the mortality of broilers during transportation or in barns has a great relationship with the highest daily environmental temperature. This paper argues that when the outside temperature is higher than 65438 07 degrees Celsius, corresponding measures should be taken to improve the adverse effects on poultry. On the contrary, Ritz et al. (2005) pointed out that when the temperature rises in hot weather, if the broiler keeps moving, the high temperature increases the risk of being slaughtered in advance when the broiler is waiting for slaughter in the slaughterhouse compared with the death during transportation. It means that it is easy to die when the temperature is high, so you should kill it quickly. )
