ARIF, M. et al. Impacts of supplementing broiler diets with a powder mixture of black cumin, Moringa and chicory seeds. S. Afr. j. anim. sci. [online]. 2019, vol.49, n.3, pp.564-572. ISSN 2221-4062.  http://dx.doi.org/10.4314/sajas.v49i3.17.

The present study aimed at evaluating the effect of a phytogenic mixture in the diet on broiler production. A total of 400 day-old unsexed Cobb broiler chicks were randomly allotted to four treatment groups of 10 replications in a randomised design experiment. The phytogenic feed mixture (BMC) contained equal ratios of black cumin, Moringa oleifera and chicory seeds. The treatment groups were as follows: T1 was fed the basal diet, while T2, T3 and T4 were fed the basal diet supplemented with 0.2%, 0.4% or 0.6% of three BMC mixture, respectively. Results showed that increasing the dietary BMC level could be associated with a gradual but significant increase in body weight and improvement in the feed conversion ratio when compared with the control group. Broiler diets enriched with 0.4% to 0.6% of the BMC mixture reduced gut microbial count of coliforms, E. coli and C. perfringens as well as gut pH, compared to the control group. Increasing the dietary BMC mixture level was associated with gradual but significant decrease in serum total cholesterol, low density lipoprotein concentrations and liver enzymes concentrations. However, there was an increase in the high density lipoprotein concentration, and glutathione peroxidase and superoxide dismutase activity in serum. In conclusion, the BMC mixture could be deemed an effective growth promoter, but further research is needed to evaluate it as a viable alternative to antibiotics.
