Abstract
In super ovulated cows, maximum value of serum progesterone was recorded after PMSG injection, or on the day of second injection of PGF₂ alpha. The super ovulatory response was judged on the basis of palpable corpora lutea on the ovaries upon rectal palpation as good ( 12 corpora lutea), moderate (6-12 corpora lutea) and poor (1-5 corpora lutea). The serum progesterone values were observed to fluctuate consider ably. Whereas, the fluctuations were not so marked in one poorly responding cow.
