Abstract

With a view to study the disappearance of central luteal cavities of corpora lutea and its relation with conception rate in pregnant and non-pregnant animals, ultrasonographic studies were conducted in 16 crossbred dairy cows; 8 to 30 days post insemination. In both the groups, the luteal cavities were present on day 8 in all the animals at the commencement of the study except in three animals where luteal cavity was not found throughout the study. The study concluded that the luteal cavity disappearance was similar in both pregnant and non-pregnant animals and the mean day of disappearance in pregnant and non-pregnant animals were 16.44 and 15.55 days, respectively. The study also concluded that luteal cavities had no effect on conception rate of the animals

Keywords: Luteal cavity, disappearance, pregnant and non-pregnant, conception rate
