Fecal nitrogen and dietary quality relationships in Fallow deer
Fecal nitrogen of free ranging and captive herbivores is correlated with dietary nitrogen, as well as other dietary chemical characteristics. Besides, only few experimental studies examined in depth the precision of these relationships. This study investigates the correlation between fecal and dieta...
