The effect of air temperature and relative humidity in climatic chamber, in Corriedale sheeps

Abstract

The pattern of chromium oxide (Cr 203) excretion was studied in ten Corriedale wethers maintaining one lot in climatic chamber at constant air temperature — 80,6°F (27°C) — and other lot maintained outside as control. In the Experiment I, the sheep were dosed twice daily with chromium  oxide in gelatine capsules form at fixed times and, in the Experiment II,  the animals consumed the marker mixed in the ration. The fluctuations in chromium oxide excretion, expressed in per cent, obtained in the two Experiments and in both environments, showed differences no significant, statistically. It was concluded that the constant air temperature of 80,6"F (27°C)  and relative humidity mean of 72 per cent held at the climatic chamber did not exert any influence on the concentrations of the chromium oxide in the faeces. In all cases, individuals large differences were observed in the diurnal pattern of chromium oxide excretion in the faeces.
