The increase in the total serum protein and albumin in this experiment is in agreement with NASSER ET AL., (1998), who reported that total serum protein as well as albumin was higher significantly when broiler chicks fed rations contains 2% and 3% of BCS in hot climate. BCS adding affected significantly the serum glucose level when compared with groups received different levels and that of the control group. These results do not agree with TOGHYANI ET AL., (2010) who recorded non significant effect for BCS on glucose level and also disagree with El- DAKHAKHNY ET AL., (2002), ZAOUI ET AL., (2002) and MERAL ET AL., (2004), who recorded hypoglycemic effect for BCS addition. Addition of BCS in the diet led to decreasing (P<0.05) serum cholesterol level when compared to control. Results agree with those obtained byTOLLBA AND AND HASSAN (2003), HASSAN ET AL., (2007) and AL-BEITAWI ET AL., (2009) who recorded that BCS significantly decreased serum levels of total cholesterol, while TOGHYANI ET AL., (2010) found that serum cholesterol concentrations were not significantly affected by supplementation of BCS. The decrease in cholesterol level may be attributed to the high content of Blak cumin from unsaturated fatty acids which may stimulate the cholesterol excretioninto the intestine and the oxidation (KHODARY ET AL., 1996). It can be concluded that feeding low levels of BCS improved performance characteristics in terms of LBW and feed intake. More studies required in this field to confirm the mechanism and mode of action of active ingredients of black cumin seed.
