Nutritional evaluation of the principal forages / feed consumed by Indian rhino (Rhinoceros unicornis) in Pobitora Wildlife Sanctuary and Assam State Zoo-cum-Botanical Garden, Assam

Abstract

Rhinos in Pobitora Wildlife Sanctuary principally feed on 22 species of grasses and plants, considering the seasonal variation on the availability of food sources. The proximate analysis of food revealed that they contain moisture (80-85%), crude protein (6-15%) and ash (10-15%). The rhinos in Assam State Zoo-cum-Botanical Garden are being maintained on a daily ration of green grasses (100kg), concentrate feed (7kg) and monthly supplements of minerals (500g). The chemical analysis of grass and feed mixture revealed that they contain moisture 11-80%, crude protein 7-18% and ash 5-14%.
