The study included 120 randomly selected lactating goats of the Bulgarian breed dairy and local cross. The animals were housed in two licensed farms in Bulgaria, under the same technological systems. Goats are grouped in to treatment groups according to age and number of lactation periods. The study aims to clarify the impact of the number of lactation and age as a factor in the spread of subclinical mastitis. Sterile milk samples have been taken of all the animals for bacteriological status and for the performance of physical and chemical analysis. The results show a clear trend of increasing intramammary infection with age and raise in number of lactation, while caprine animals aged 2-3 years, the affected dairy halves are 20%, while those age dover 8 years affected halves are 56.7 %. Isolated pathogens are mainly from the group of coagulase-negative staphylococci.
