The study were carried out to evaluate the effect of supplying the diets with some medicinal herbs powders of thyme (Thyme Vulgaris) and red pepper (Capsicum Annum) as well as the probiotic on some productive performance of broilers (Arboracer) in a duration of 42 days.

A total of 160 one day old unsexed chicks were used allocated to four treatments (two replicates/ treatment , of 20 chick/replicate).

The first treatment as control, The second and third treatment were supplied by 0.5 % thyme and red pepper powder respectively and the forth treatment supplied by 0.1% probiotic.

The results showed that the bird fed the diet contained red pepper had significantly (p≤0.05) better weight, weight gain، feed conversion ratio, feed efficiency production index and the lowest mortality when compared to control group.

No significant difference (p≤0.05) were found between diets added thyme، probiotic as compared to control group in body weight، weight gain، feed intake، feed conversion ratio although the production index value was improved for these two treatments.
