N2  - Thirty-two pregnant Barki ewes (last 4-6 weeks of gestation period) 2nd to 3rd seasons were divided into four similar groups (8 ewes each). The first group (control group) (T₁) was fed a basal diet contain 700g concentrate feed mixture (CFM), 2kg berseem and 250 g wheat straw. The other three groups T₂, T₃ and T₄ were fed the same ration of T₁ plus 75, 100 or 125 mg/kg live body weight (LBW) Euclyptus globulus leaves (EGL), respectively. Performance of newborn lambs and ewes were taken in addition to some blood parameters. Results obtained could be summarized as follows. Lamb performance indicated that gain and average daily gain (ADG) of suckling lambs significantly improved (P≤0.05) by adding of EGL with low supplementation level, but the difference between groups of the other supplementation levels and control group were not significant (P≥0.05). Milk production from ewes indicated that 4% fat corrected milk was significantly increased (P≤0.05) with low supplementation level and significantly decreased (P≤0.05) with medium and high supplementation levels when compared with control group. Also, Feed efficiency as g DMI / g milk yield was improved by 25% with low supplementation level. Results of milk composition cleared that supplementation of EGL significantly increased (P≤0.05) Fat%, CP%, TS% and ash%. Blood analysis indicated that adding EGL significantly increased total protein of blood serum, but the difference between T₁ and T₂ was not significant, also, GPT was significantly increased with T₃ and T₄ but the difference between T₁ and T₂ was not significant. Also, results of A/G ratio for T₁, T₂ and T₃ were not significant, but the result of T₄ was significantly decreased. The same result was obtained for serum blood urea. Other blood parameters like albumin, globulin, GOT and triiodothyronin activity were not significantly difference. Also, results indicated that serum total protein and albumin were higher in lactation period than in late gestation period, but the parameter of A/G ratio was significantly higher in late gestation and first two weeks of lactation period than other period during lactation period. Moreover, Triiodothyromine was significantly higher (P>0.05) in late gestation than lactation period
