The aim of this experiment was to study the influence of field beans (FB) and also birds age on some production performances of commercial layers. Raw Faba Bean (RFB) 10%, 20% and 30% were compared with Roasted Faba Bean (RoFB) 10%, 20% and 30%, and both groups were compared with control C. The experiment was performed in a seven-group laying test with 3 repetitions, with a total number of 630 birds aged 43 weeks. Body weight (BW), egg production (EP), feed consumption (FC), and feed conversion ratio (FCR) were studied. BW was not essentially affected by treatments. A significantly higher EP was observed in T4 (10% RoFB). The lowest EP was registered in T2 (20% RFB) and T3 (30% RFB), but values in T1, T5 (20% RoFB) and T6 (30% RoFB) groups were insignificantly higher than C. In the group T2 there was a significant reduction in FC, and a significant increase in the group T4 was observed. A significantly higher value of FCR was observed in T4, while significantly lower values were obtained in T2 and T3. An increase of the birds age had not essential effects on the BW of hens, but other values were significant and fluctuated in our experiment. EP decreased insignificantly from the week 44 of birds age. FC increased significantly and progressively with advanced ages. FCR was lowered gradually and significantly as the age of the birds increased.
