Mastitis is a disease of the mammary gland that negatively influences the quantitative and qualitative parameters of milk. At the same time the milk from a mastitic gland is a source of infection to both other animals and the consumer and therefore a direct threat to human and animal health. This determines the importance of an early and accurate diagnosis of the various forms of inflammation of the mammary gland in goats. Clinical signs, measurement of somatic cells in milk and bacteriological examination are standard methods for diagnosis of mastitis. Bacteriology is not suitable as a routine first line test to identify subclinical mastitis. Therefore, indirect tests for the diagnosis of mastitis are more suitable for application in practice, and based on their results, samples can be selected for further examination. The purpose of this article is to look at the different test available for the diagnosis of subclinical mastitis in goats, based on various indicators of inflammation in the mammary gland.
