Faecal nitrogen as an indicator of the nutritional status of kudu in a semi-arid savanna : research article

Faecal samples from eight confined kudu populations were collected from May 1999 to December 1999. Samples were analysed for nitrogen concentration. Faecal nitrogen concentration (N f ) reached a low during the dry-hot season (August to the end of October) and peaked in November. Nlsubgfl/subg was negatively correlated with kudu density for samples collected during June, August and September. Populations where animals in poor physical condition were observed and for which mortalities were reported had significantly lower ( P < 
0.05) dry season Nlsubgfl/subg values compared to populations in apparently good condition. The results suggest that Nlsubgfl/subg was a useful indicator of the nutritional status of kudu under the study conditions.
