Abstract

This experiment was carried out to investigate of the early pregnancy diagnosis by finger pressure method, mucus smear method and rectal palpation method in 169 heads of pregnant dairy cow. 1. Pregnancy diagnostic rate of previous, middle and late period of pregnancy by finger pressure methods were 87.3%, 82.0% and 70% respectively. 2. Pregnancy diagnostic rate of previous, middle and late period of pregnancy by mucus smear methods were 83.1%. 94.9% and 95.0% respectively. 3. Pregnancy diagnostic rate of previous, middle and later period of pregnancy by rectal palpation methods were 83.1%, 96.1% and 100% respectively. 4. Pregnancy diagnostic rate of early pregnancy by finger pressure method, mucus smear method and rectal palpation method were 86.7%, 86.8% and 66% respectively. 5. Accordingly, finger pressure method in pregnancy diagnosis is thought to be recommendable because this early diagnostic means are simple with accurate results.
