A brief introduction to the main points of prevention and treatment of duck heatstroke
Duck heatstroke, also known as heat stress, is an acute disease caused by disturbance of heat dissipation mechanism and destruction of heat balance in ducks under the condition of high temperature and high humidity. If the disease is not dealt with in time and effectively, a large number of ducks will die, thus causing greater economic losses to breeding. The main causes are as follows: 1.
