The purpose of this study was to investigate the prevalence of mastitis and dynamics of different mastitis forms in goats during lactation and the dry period .The prevalence of mastitis was analyzed in 250 goats. Parallel traced 52 dairy halves with different mastitis forms during lactation and 56 halves during the dry period. Express diagnosis was made on the farm with rapid mastitis test CMT-Test (Kruuse, Denmark) and test Porta SCC (Porta Check, USA). For precise determination of the health condition of all dairy halves was conducted laboratory analysis including determining the number of somatic cells by Fossomatic (Foss, Denmark) and microbiological testing for isolation of pathogenic microorganisms. Prevalence of mastitis was found within 45.8 % and results indicated that 41.67 % of the cases diagnosed with subclinical mastitis in early lactation, persisted at the end of the lactation period. At the same time the latent infection persisted in 15.38 % while secretory disorder was in 26.67 %. During the dry period the highest percentage of persisting indicated subclinical mastitis - 71.43 % and only 14.29 % were found healing, compared with secretory disorder that persisted in 42.86 % as they were healed halves. The latent infection persisted also in 42.86 %, but healing again was found only in 14.29 %. Non-clinical mastitis in the absence of the treatment are stored in 76.19%
