Effect of feeding black cumin combined with vitamin C was summarized in Table 2. Addition of
vitamin C combined with black cumin at whatever levels did not affect blood LDL as compared to the diet with
vitamin C alone. Feeding black cumin at 0.5 to 0.75% tended to results lower blood LDL, although statistically
it did not significantly different. The results suggest that active substance especially phytosterol of black cumin
has the minor ability to lowering LDL (bad lipoprotein) in the blood of the chicken. The chicken with slightly
low blood lipoprotein indicated that those birds were able to produce healthy productivity.
No significant effect of feeding black cumin in reducing LDL can be caused by difference effectiveness
of active substance which is also closely related to the condition of the individual broiler. This is in accordance
with the report of Al - Jawfi (2008) that the difference levels of cumin origin and condition of the broiler
brought about the difference effectiveness of active substances of cumin. In addition to differences of active
substances content of black cumin, can be possibly caused by the lower use of black cumin with the level not
more than 1%. This result agreed with Sohail (2012) who reported that supplementation of 4% or 5% black
cumin significantly decreased serum LDL cholesterol.
In contrast to the present results, previous research has shown that black cumin can reduce cholesterol,
as black cumin contain oleic acid (Omega 9), which is an important substance of the omega family in a form of
monounsaturated fatty acids or mono unsaturated fatty acid (MUFA), it also has an efficacy to reduce LDL
cholesterol (bad lipoprotein). An active substance of black cumin content phytosterol, have the ability to
compete with cholesterol absorption in the intestine and finally resulted in reducing the absorption of cholesterol
(Richard, 2011).
