This study examined the effect of adding cumin powder to the diets of growing Karadi male lambs on growth performance, blood traits, growth hormone (GH), and insulin-like growth factor-1 (IGF-1). Twenty lambs with an average starting weight of 24.7 ± 1.6 kg were divided randomly into four groups for 90 days. The first group received a basal diet without cumin powder, while the other groups received diets containing 1%, 2%, or 3% cumin powder.

Body weight, feed intake, and feed conversion ratio (FCR) were recorded during the experiment. At the end of the trial, blood samples were taken to measure blood parameters and serum levels of GH and IGF-1.

The results showed that cumin powder improved several blood traits, including red blood cell count, hemoglobin level, packed cell volume, and white blood cell count compared with the control group (P < 0.05). The lambs fed 3% cumin powder showed the highest values in most cases. However, mean corpuscular volume, mean corpuscular hemoglobin, and platelet count were not affected significantly by the treatments.

Cumin supplementation also improved growth performance. Lambs fed cumin powder had greater final body weight, higher daily weight gain, and better feed conversion efficiency than the control group. The best results were found in the lambs fed 2% cumin powder. In addition, serum GH and IGF-1 concentrations increased significantly in the supplemented groups, especially in the 2% cumin group. Feed intake was similar among all groups.

Therefor, this study was conducted to evaluate the effect of different dietary level of Cumin powder on growth performance, hematological parameters and growth-related hormones in karadi lambs.

In conclusion, adding cumin powder to the diets of Karadi lambs, particularly at the 2% level, improved growth performance and increased hormones related to growth.
