ترجمه مقاله ارزیابی گیاهان مختلف دارویی به عنوان تقویت کننده رشد جوجه های گوشتی

This study was conducted to determine the comparative efficacy of six medicinal plants including Nigella sativa, Boerhavia diffusa, Withania somnifera, Ipomea digitata, Azadirachta indica and Corylus avellena @ 4 g/kg of feed as growth promoter and their subsequent influence on the performance of broilers. 210 day old chicks were randomly divided into 21 experimental units of 10 chicks each. These experimental units were randomly allotted to 7 treatments comprising of 3 replicates each. Commercially formulated broiler starter and finisher rations were offered ad libitum from 0-4 and 4-6 weeks of age. Authenticated samples of the plant materials were dried in shade, pulverized and mixed each @ 4g kg-1 of feed and offered to the chicks of the respective treatment groups. Maximum gain in weight was observed with the Withania somnifera (1.819 kg) followed by Nigella sativa (1.805 kg) and Azadirachta indica (1.800 kg). The best cumulative FCR at the end of 6th week of age was for that of Withania somnifera (2.038) followed by Nigella sativa (2.054) and Azadirachta indica (2.083). The lowest results as regards FCR were recorded for Ipomea digitata (2.394) and Boerhavia diffusa (2.396). The results of the Corylus avellena (2.209) and control (2.235) were statistically similar. The maximum profit per bird was obtained from Azadirachta indica treated birds followed by Nigella sativa and Withania somnifera treated chickens as compared to control. It was concluded from this study that medicinal plants especially Withania somnifera, Nigella sativa and Azadirachta indica can be used as growth promoters in the poultry diets with better production performance.
