Název v původním jazyce

Estimating of the red (Cervus elaphus) and roe deer (Capreolus capreolus) diet quality by near-infrared reflectance spectroscopy

Popis výsledku v původním jazyce

Faecal nitrogen (FN) content was analysed in 168 pellet groups from red and roe deer in the growing season and in winter both by standard Kjeldahl method and by NIRS analysis. Estimates of nitrogen content obtained by the two methods did not differ (P >0.1) and the correlation between FN values was significant (P < 0.001). FN content ranged from 1.10 to 4.58% of dry matter and, as anticipated, it was higher in the growing season than in winter in both species (P < 0.01). Faecal nitrogen values were also higher for roe deer than for red deer, although the difference was only significant in the growing season (P = 0.007). This study confirmed that faecal nitrogen of free-living ruminants can be accurately determined with NIRS analysis. NIRS represents alow-costs analytical technique, which could replace conventional laborious methods and is highly promising for analyses of diet quality in free-living ruminants.
