The paper focused on the evaluation of a fatty acid profile and mineral component contents in milk obtained from cows of 5 breeds maintained in Poland. The studies covered 147 milk samples collected from cows of Polish Holstein-Friesian black-white (42) and red-white (26) varieties, Simental (31), Whitebacks (15) and Polish Red (33). Milk was sampled at the spring-summer season when dietary units included green forage. It was found that the milk gained from the cows of 3 breeds (in that two native), i.e. Whitebacks, Polish Red and Simental, had the fatty acid ratio most beneficial for human nutrition. Significantly higher proved to be a conjugated linoleic acid (CLA) level. The milk also contained more essential macro- (K, Ca, Na, Mg) and some microelements (Zn, Fe). A vital effect (beside the breed) was likely to have a feeding system of animals supplied mainly with pasture fodder.
