Description
Lawrence O Barros and colleagues published a 2026 study of egg follicle cycles in plains zebras. Follicles are the small sacs in the ovary where eggs mature. Breeding plans for this declining species need such detail, yet no ultrasound study had tracked zebra cycles day by day.
Staff scanned four mares daily through natural cycles with no added hormones. Cycles ran long, at about thirty-eight days between egg releases. Few follicles grew at once, growth was slow at about one millimeter a day, and no wave pattern appeared. Womb lining patterns matched those of horses near egg release. Two mares also responded well to drugs that sync cycles. The data can guide zebra breeding work.
