First, the cause of the disease due to the hot climate, due to their own physiological characteristics of laying hens, drinking water increased significantly; summer high temperature and humidity conducive to a large number of breeding bacteria breeding; raw material storage time is too long to mold, especially corn mildew, is a direct One of the reasons for this is the high salt content in feeds, the use of low-quality fishmeal, the indiscriminate use of antibiotics, the high calcium content in the diet, and the high crude fibre content that are responsible for the development of intractable watery diarrhoea in chickens.
