The aim of this study was to investigate the effect of 50 % water restriction on blood hormones, minerals and metabolite in baladi goats during summer months (June – August). Ten non-pregnant and non-lactating balididoes (1.5-2 years old and average BW = 23.4 ± 1.3 kg), divided equally into two groups of 5 does each. The first group (treated) received 50% of water requirements (G1) while the other assumed as control (G2) (ad libitum water). Temperature – humidity index (THI) was calculated. Body weight (BW) and thermoregulatory response, rectal temperature (RT) andrespiration rate (RR) were recorded. Blood serum metabolites and mineral (total protein (TP), albumin (Alb), globulin (Glb), triglycerides (TG), cholesterol (Chol), glucose (Glu), Na+, CL- and K+) were determined. Kidney (creatinine and urea) and liver (ALT, AST) function and serum hormones (Triiodothyronine (T3), thyroxin (T4), aldosterone (Ald), progesterone (P4) and estradiol E2) were measured and Haematological parameters (CBC) were assayed.Blood biochemical analysis indicated that the blood serum albumin, cholesterol, triglycerides, Na+, K+, Cl-, ALT, AST, Create and urea were not affected by water restriction. It was also, no changes in serum hormones were observed in water restricted does. Although, serum total protein and globulin were higher (P<0.05), serum glucose was significantly reduced (P<0.05) in treated goats. Blood picture as affected by treatment showed an increase (P<0.05) in MCHC and decrease in HT, MCV and Platelets while Hb, MCH, WBCs and RBCs were not affected. It is concluded that baladi goats can easily survive under semi-arid areas.
