It was aimed to determine the structural condition of the barns in 220 randomly selected dairy cattle enterprises in Konya and Aydın provinces. The material of the study consisted of data from 117 enterprises from Konya province and 103 enterprises from Aydın province. Between January and March 2024, a face-to-face questionnaire was applied to the breeders. It was found that 57.27% of the shelters were semi-open, 76.21% used concrete floors, 71.82% had foot diseases, 36.36% cleaned feces mechanically and 51.82% had less than 50 animals. As a result of regression analysis, while the effect of number of milkings, type of barn and the presence of a brusher on average daily yield was found to be significant (p<0.05), the effect of stall litter material, presence of ventilation chimney, stool cleaning method, hoof care frequency, milking method, drinker type and ventilation system was found to be insignificant (p>0.05). According to the chi-square test, there was a relationship between the cities (Konya and Aydın) and the breed, shelter type, barn and stall floor, stall litter material, wall construction material (p<0.05). Structural conditions of barns directly affect animal welfare. In Konya and Aydın provinces, the structural conditions of the barns should be improved, and welfare should be given importance. The necessary feasibility studies for the improvement of the barns should be carried out during the establishment phase of the enterprises and the benefit/loss ratio should be evaluated. Since the good structural condition of the barns is related to animal welfare, the goal should be to achieve the best. For this purpose, it is suggested that training should be organized to inform breeders and these trainings should include topics such as: designing shelters that meet the needs and allow for changes, animal behavior and welfare, and breed-specific characteristics.
