Abstract: The consumer of lamb meat relates the potential development of animals to use of growth promoters however, now-a-days the alternative nonantibiotic feed additives have improved the animal performance and health. The objective of the present trial was to evaluate the use of the herbal natural growth promoter in lamb production. Assessment was based on the performance of the animal when fed a commercial diet and the use of the herbal natural growth promoter. With the herbal, lamb weight and average daily gain were 0.270 g (p<0.05) however, the feed intake was not affected (p>0.05). The level of the herbal promoter had no effect on the back fat (p>0.05). Based on the results of the study, it could be concluded that with the herbal growth promoter, performance of the lambs can be improved.
