Özet
The relationships of udder and teat morphology, parity, and lactation stage with subclinical mastitis were investigated in cows raised in herds registered with the Izmir Holstein Breeders Association. Data from 887 cows in 21 herds were used. The udder and teat morphology of the cows was scored. Detection of subclinical mastitis was performed by a hand-held device measuring the electrical conductivity of the milk. It was found that 55.9% of cows had trough-shaped udders, 25.9% had ball-shaped udders, 11.5% had rear-heavy udders, and 6.7% had pendulous udders. Teats were cylindrical in 73.3%, funnel-shaped in 18.8%, pear-shaped in 3.2%, and long and thick in 4.7% of cows. Teats were located squarely in 54.1% of cows, and rear teats were closer to each other compared with the front teats in 45.9%.
