The survey of material briefly describes the brecds an the number of animals uscd in this investigation (Table I).
500 cows were testcd in this study. Rectal examinations and vaginal inspections for advancing pregnancies were carricd out every
month. The cows were chosen from the State Farms (Çifteler, Konya,
Lalahan). The limits of pregnancies in these cows were between 32
days and 292 days.
