Journal Title: International Journal of Farming and Allied Sciences - Year 2014, Vol 3, Issue 1
Abstract
This study was conducted to investigate the effect of different levels of Azolla (Azolla pinnata) on performance and carcass characteristics of broiler chicks. one-day-old male broiler chicks (Cobb- ) with treatments and replications ( birds per replicate) were used. Experimental diets were a corn-soybean based diet with no Azolla (control) and diets containing , and % of Azolla. Results indicated that in all rearing periods between treatments, chickens fed diets containing Azolla powder significantly (p< ) had an improved daily weight gain (DWG) and feed conversion ratio (FCR) compared to other diets. So that the lowest feed intake, the highest weight gain and lowest (best) feed conversion ratio is related to diets containing Azolla. There were no mortality among the experimental groups. Supplementation of Azolla powder significantly increased of carcass efficiency percentage (p< ) and thigh relative percentage (p< ) while, the lowest its percentage is related to diets containing Azolla. There were no significant differences among treatments for abdominal fat, liver, gizzard and breast relative percentage. The lowest feed cost per kg of body weight was observed in diets containing Azolla .
