In a mare, ovulation usually occurs at which stage of the oestrous cycle?
Correct answer: C. Near the end of oestrus
- A. During the middle of anoestrus
- B. At the start of dioestrus
- C. Near the end of oestrus
- D. Immediately before pro-oestrus
Explanation
Mares commonly ovulate about one to two days before the end of behavioural oestrus. Ovulation is therefore associated with late oestrus rather than the non-receptive dioestrus or anoestrus phases.
