Abstract
The aim of the paper was to evaluate the effect of season on milk yield and quality. Researches were carried out at the Research and Development Station for Bovine Raising Arad, on milk collected daily in the farm from around 350 cows, between years 2009 and 2011. The following traits were studied: total milk yield, average milk yield per cows per day, milk fat percentage and milk protein percentage from the bulk tank. The evolution per month and season (spring, winter, summer and autumn) of these traits was studied using statistical inference. Results showed that milk production was lower in the winter and spring seasons than in summer and autumn.

Key words: milk, quality, yield, season
