Water deprivation and its effect on some blood constituents in Idmi Gazelle, Gazella gazella

Water deprivation and its effect on some blood constituents was studied in the Idmi Gazelle, Gazella gazella. Animals were deprived of water for 8 d in winter and 3 d in summer. Blood was collected and analysed during three phases of experimentation; hydrated, dehydrated and rehydrated. The gazelle's dehydration led to an increase in many of blood parameters such as RBCs, WBCs, PCV, Hb, serum Na+, Cl−, BUN and serum osmolality. The gazelles seem to be well-adapted physiologically to live in harsh desert extremes. Possible implications obtained from the results would be useful in captive breeding of this species.
