ULTRASONOGRAPHIC EVALUATION OF LUTEAL GROWTH AND REGRESSION CHARACTERISTICS IN CROSSBRED CATTLE
With view to study the luteal growth and regression pattern, ultrasonographic studies were carried out in 10 apparently healthy crossbred dairy cattle at 24 hour interval from the day of ovulation to next oestrus. In all the animals the span of corpus luteum (CL) was completed in three phases like...

| description | With view to study the luteal growth and regression pattern, ultrasonographic studies were carried out in 10 apparently healthy crossbred dairy cattle at 24 hour interval from the day of ovulation to next oestrus. In all the animals the span of corpus luteum (CL) was
completed in three phases like growth, stationary and regression phase. First appearance of CL by transrectal ultrasonography (TRUS) was
detected on third day of ovulation and was imaged as poorly defined, uneven, greyishblack structure with echogenic spots within the ovary. An increased growth rate of CL was noticed up to day 8 post ovulation, formed the growth phase. Mean maximum diameter of CL was observed on day11.From day 8 to day 16 of ovulation the luteal growth rate is in a stationary phase and the luteal regression observed from day 16 or 17 post ovulation. |
