The analysis of the cell population present in the milk and colostrum of goats represents basic morphological characteristics of milk, through which the health of mammary gland and of the milk intended for the consumers can be determined. The purpose and the goals of these determinations consisted in comparative, quantitative and qualitative evaluation of the cellular content from raw milk and colostrum of goat from two lots of goats, clinically healthy, the breeds being French Alpine (n = 10) and Romanian Carpathian (n = 10). Morpho-physiological investigations were conducted during March-July 2015, on samples of raw milk and colostrum, using Squash technique, panoptic colored (Dia-Quik-Panoptic), and milk cytogram method. Microscopic examination revealed that the milk cytogram of both breeds’ colostrum shows a higher frequency of epithelial cells, lactocytes in various forms of activity, lymphocytes, macrophages. The highest frequency was for neutrophils. The milk cytogram in raw mixture milk indicates that the cell population is very similar for both races, with same increase or decrease in those studied months. The neutrophils reached an average of 45.7% for the Alpines, respectively 46.17% for the Carpathians. There were no significant differences of interest regarding cell population of raw milk and colostrum of both races. In conclusion, the results support the need for correlation between quantitative and qualitative microscopic cytological tests on smears because there are no standards in automated system for goat milk in terms of health assessment of the mammary gland and of safety of the milk meant for consumers.
