To provide a more stimulating captive environment and to illicit species-specific behaviours, a review of the enrichment techniques used for two browsing ruminants, (the giraffe (Giraffa camelopardalis) and the Mhorr gazelle (Gazella dama mhorr), held at Twycross Zoo was undertaken. It is well known that the majority of giraffe in captivity will develop some form of abnormal behaviour (EAZA, 2006) and hence enrichment protocols are vital in keeping animals occupied and stress-free.
