The following is a feed store training tutorial with sample test questions and a short test.
Disease - A disease, by definition is a deviation from normal health. The effects of disease can range from reduced production, loss of energy, to death. Disease can be infectious or non-infectious. Infectious diseases are caused by germs (microscopic organisms). In poultry, there are four main classes of disease causing agents: bacteria and viruses (germs) and fungi and parasites. Parasites can be internal, as with worms and protozoa or external such as mites and lice.
