Growth, size and the timing of births in an individually identified population of oribi

摘要: Summary This paper describes observations on body size, growth, and the timing of births in an individually identified population oribi (Ourebia ourebi, Zimmermann 1783) Serengeti National Park, Tanzania. Females tended to be larger approximately 2 kg heavier than males. Young grew rapidly, attaining near-adult size about 7 months. Horns appeared male at 4½ months age rapidly up 20 age. Births occurred all year but were most common between March June. The results provide observational means estimating sub-adult by adult oribi, age, horn length.
