This experiment was conducted to determine and compare the effects of Russian Comfrey meal and Acacia leaf meal on the growth of chicks. The results obtained were summarized as follows; 1) In body weight gain, the significant difference (p$lt;0.01) was observed between the treatments. The control lot (Vitamin supplemented) was highest (p$lt;0.01), and Acacia leaf meal and Russian Comfrey meal lots were higher(p$lt;0.01) than non-Vitamin supplemented lot(NC). Among the treatments Acacia leaf meal was supperior than Russian Comfrey meal in order of Acacia 10% (T6), Acacia 5% (T5), Russian Comfrey 5% (T2), Russian Comfrey 10% (T3), Acacia 2.5% (T4), and Russian Comfrey 2.5% (T1) lots. 2) In feed intake, the significant difference (p$lt;0.01) was observed between the treatments. Control ration lot (C) showed higher than the other ration lots and non-Vitamin supplemented lot (NC) showed the lowest feed intake (p$lt;0.01). Acacia ration lots were higher than Russian Comfrey ration in order of 10%, 5% and 2.5% level. 3) The feed efficiency was the highest with the control lot, followed by the Acacia leaf-meal, and non-Vitamin supplemented ration had the lowest feed efficiency. Increasing level of Acacia leaf meal or Comfrey meal, gradually decreased the feed efficiency. 4) In economical analysis, Control lot was supperior than the other lots. Acacia leaf meal and Russian Comfrey meal lots were more beneficial than non-Vitamin lot (NC). Acacia supplemented lots showed supperio than all Russian Comfrey supplemented lots in order of 5%, 10%, 2.5% level.
