The aim of the study was to investigate and assess integration and logistic activities in dairy farms operating in the FADN regions of Mazovia and Podlasie. The study used primary data from studies conducted by the author in 2013 on a target group of 100 households. The investigated population of farms was divided in terms of the number of cows in the following groups of up to 10 cows (9 households), 11–20 cows (27 households), 21–30 cows (31 households), 31–40 cows (14 households) and above 40 cows (19 households). The study used the survey method using questionnaire interviews. The research shows that farmers most frequently collaborated on the joint use of equipment and supplies of agricultural inputs. In contrast, farmers in the study frequently sold products to processing companies or intermediaries.
