The aim of this study was to compare the composition and properties of goat, ewe and cow milk. Bulk milk samples were collected from White short-haired goats (G, n=60), Tsigai ewes (E, n=60), Holstein cows (H, n=36) and Czech Pied cows (C, n=93). The herds were kept in different conditions with regard to altitude, environmental temperature and precipitation. Milk composition of the species studied differed significantly. Sheep milk was characterized by high concentrations of fat, crude protein and casein (7.58%, 6.32% and 4.96%, respectively), and the best curd quality. The worst curd quality was observed in goat milk. Significant differences were also found out in some undesirable metabolites such as acetone (8.06 mg/L in E, 4.82 mg/L in C, 3.2 mg/L in G and 1.6 mg/L in H) and urea (63.6 mg/100 mL in E, 50.6 mg/100 mL in G, 40.4 mg/100 mL in H and 26.7 mg/100 mL in C). High values of these metabolites indicated that the health state of the animals was not good in some of the herds studied.
