Within the Bovidae Family the information about composition and characteristics ofcolostrum and milk belong almost exclusively to two sub-families: Caprinae andBovinae. About Hippotraginae sub-family, there is a lack of information concerningthese subjects; only few data about gross composition from few species can beachieved. Previously we reported electrophoretic similarity between milk proteins ofsable antelope and goat. The aim of this work is to expand the information on thisspecies to identify similarities and differences among members of Bovidae Family, toimprove the management works in zoos and reserves. For that, we determined activityof amylase, lysozyme (Lz) and lactoperoxidase system components (LPO) in colostrumof a H. niger female at the end of gestation. The results shows: a) presence of lesseramylase activity than those present in Perissodactyla species, but similar to thatobserved in cattle, where it is relatively small; b) a low bacteriolytic activity due to Lz,which was similar to that found in goats; c) LPO activity of . 8U/L, and a SCNconcentration. 17 ppm. Although these results should be considered as indicative,they contribute to consolidate the concept of similarities within milk componentfunctions in members of bovid´s family.
