This handbook highlights some of the most common infectious and non-infectious diseases affecting goat herds in Mongolia. We have focused on the diseases seen during the kidding season and those that affect the fertility of the breeding males and females. Cashmere breeding bucks and does and their offspring are very aluable animals. Measures should be taken to prevent disease outbreaks and ensure the health of the herd. This section of the herder manual is designed as an aid to herders in the prevention, diagnosis and treatment of some common diseases but is by no means complete and does not replace a good relationship with the local veterinarian. It is important that the herder establish a relationship with the local veterinarian to design a herd health program, treat common diseases and obtain an accurate diagnosis and effective treatment of unusual disease outbreaks.
