Abstract
Eight ~ucks (1.5-2.5 years old) of each B~ladi. Gabali and their crossbred werel exposed to water deprivation during winter and summer seasons at Maryout Research Station, which belongs to the Desert Research Center and located 35 km southwest of Alexandria. Exposure of Baladi. Gabali and their crossbred goats to four days wate~rl deprivation in both summer and winter seasons reduced body weight, free wate intake and feed intake. The reduction in body w6lght was the highest in crossbre (16.6 %) fol/owed by Baladi (14.2%) and Gabali (9.7%) and it was higher in summe (15.40/.) than in winter (11.6%). Likewise. total dry matter Intake decreased by 29.4 27.6 and 25.5% in crossbred. Gabsli and Baladi goats, respectively and wa pronounced in summer (29.7%) compared to winter (25.3%). After rehydration animals returned to consume more feed. Water deprivation resulted in an increase 0 RT and a decrease of both RR and PRo These effects were obvious during summer. Blood and plasma volumes were decreased (P<O.01) in dehydrated animals indicating hemoconcentration particularly in Gaball bucks compared to the other two breeds1 Meanwhile. PCV percentage was the highest in the crossbred bucks. Blood glucose decreased (P<O.01) due to dehydration in 8aladl followed by Gaball and crOssbred bucks.
