Energy and mineral nutrition and water intake in the captive Indian rhinoceros (Rhinoceros unicornis)

Abstract: In the captive Indian rhinoceros (Rhinoceros unicornis), two disease complexes with a high incidence-chronic foot problems and uterine leiomyomas-may be linked to excess body weight (BW). In this study, intake and digestion trials were conducted (by means of 7-day weigh-backs, and 5-day total fecal collections, respectively) with I I Indian rhinoceroses at four zoological institutions in Europe and the United States to quantify energy and mineral nutrition on conventional or roughage-only diets.

“…Concentrate feeds usually contain more available P as compared to roughages feeds (Clauss et al., 2005). As a result, intake of P was higher on rations with concentrates.…”

“…In addition, concentrate supplementation may improve the supply of minerals which otherwise deficient in forage‐based diets. Mineral deficiency/imbalances have been widely reported in livestock and wild animals (Clauss et al., 2005; Sharma and Joshi, 2005). However, excessive feeding of concentrates may adversely affect rumen function leading to acidosis and may also cause obesity (Clauss et al., 2005) and imbalance/excess of one or more minerals.…”

“…Energy requirement of elephant is not known. However, based on review of literature (Meyer & Coenen 2002;Clauss et al 2005), DE requirements have been set at 144 kcal DE/kg BW 0.75 for maintenance, beyond which obesity was suspected. Further, 1.25 times maintenance DE has been recommended for working horses (NRC 1989).…”

“…Linking these to published energy densities of potential foodstuffs, the amount of food necessary to meet these requirements can be estimated. In the absence of measured values for either urinary energy losses or methane production and the apparent lack of a heat increment of feeding (Gallivan and Best 1986), ME was assumed to be 90% of digestible energy (Robbins 1993;Clauss et al 2005). Standard metabolic rate (SMR) was calculated using the Kleiber (1975) equation (SMR p 3.4 mass 0.75 ) and converting to megajoules per day.…”
