The present study was aimed to define the factors affecting the adoption of innovations in dairy cattle farms in Balıkesir and Çanakkale provinces in TR22 South Marmara Region, Turkey. The data were collected from 221 farms by a stratified random sampling method. The study was performed between March and November 2019. This study was used the ordered probit model to evaluate the data. The results revealed that the age of the farmers, household size, dairy cattle experience, household income, the number of dairy cattle, frequency of the internet use, meeting frequency with other farmers and contact frequency with agricultural extension personnel had a positive impact on farmers' adoption of innovations; whereas farmers' contact frequency with veterinaries had a negative impact. As a result, farmers' adoption of innovations in dairy farming activity can be increased with farmers who are open to innovations regarding animal husbandry and knowledgeable about the importance and the necessity of innovations adoption.
