Energy has been one of the key factors that influence the welfare and performance of an animal’s farm. The whole study was performed at the Department of Animal Science, Animal Farm, College of Agricultural Engineering Sciences, Sulaimani University, Kurdistan Region-Iraq. Sixteen adult black does, 1.5-2 years old have been used and randomly divided into two classes (8 does + 8 does), and reared in single pens (1.20 x 1.10 cm). The groups were fed two levels, 300 g / day as low-level feed (0.9 Mcal ME) and 600 g / day (1.8 Mcal ME) as high-level feed for 8 weeks of mating season (4 weeks before matting and 4 weeks after matting). This study aimed to study the effect of two levels of energy on live body weight, body condition score, and some hematology parameters. The obtained results throughout all periods showed no significant variations in live body weight and body condition score of does fed either with low or high concentration levels. Moreover, in beginning the experiment HCT % and PLT were significantly increased (p<0.05) for T2 (high level) whereas an insignificant change in other parameters. After 4 weeks the white blood cell count (WBCs), L%, PLT, and PCT % were significantly increased (p<0.05), (WBCs) and L% for T1 (low level) and PLT, PCT % for T2 (high level). After 8 weeks, MO %, HCT %, and PLT were significant differences (p<0.05), MO % for T1 (low level) and HCT%, PLT for T2 (high level), while other parameters were not significant.

Key words: Doe, Live body weight, Body condition score, Energy and blood parameters.
