Cows on high and low feeding levels were submitted to palpation of the ovaries and recording of the presence and size of follicles at various days of the cycle. A mid-cycle rise in follicular activity was apparent and for which the nonovulating ovary was responsible. High level feeding stimulated ovarian activity in each of the 2 ovaries throughout the cycle and follicular activity commenced earlier in the ovulating ovary on high level feeding than on low level feeding. A larger number of inseminations per conception was required by cows on high level feeding on low level feeding. The effect of ovarian activity on fertility is discussed.
