Reproductive biology

All members of the Cephalophinae subfamily are monogamous, generally producing one litter per year. Females are sexually mature at approximately nine months of age, males between 12 and 18 months. Cephalophinae are non-seasonal breeders, but in some species such as the bush duiker (Sylvi-capra grimmia), calf births may peak during the summer months. Gestation among the Cephalophinae can be as short

as four months or as long as nine months. Single births are the norm, but it is not unheard of for bush duikers to bear twins. Male duikers do not participate in rearing apart from delivering warnings about nearby predators and defending the trio's territory. Most calves are weaned from their mothers between five and nine months of age.
