Diarrhea in goats can be classified into several types based on the underlying cause. It can be infectious, nutritional, or environmental. Infectious causes often include bacterial infections (such as E. coli and Salmonella), viral infections (such as coronavirus), or parasitic infestations (such as coccidia and worms). Nutritional causes can arise from sudden diet changes or the consumption of moldy or poor-quality feed. Environmental factors, including stress from transport, changes in weather, or overcrowding, can also contribute to the onset of diarrhea.
