In a population of free-ranging Cape mountain zebra, median age at first foaling was 67 months (range 38-105 months), median foaling interval was 25 months (range 13-69 months) and annual foaling rate was 32%. Foaling rates of younger and older mares were similar. Foals were born all year round with a peak corresponding to the rainy season (summer). Conception occurred later in the season when the spring was dry.
