This study was conducted to investigate the effect of using different levels of dried Azolla (DA) on some economic evaluation parameters of broiler chickens. A total of 200 healthy unsexed one-day-old broiler chicks (Cobb type) were allocated randomly in to four groups (50 chicks/each group). Each group consists of three replicates. DA was chemically analyzed and used as 0%, 4%, 8% and 12% to formulate 4 balanced experimental diets (Control, T4, T8, and T12, respectively). Results revealed high positive and negative correlation among the different studied productive and economic variables. Total production function among the experimental groups, showed a significant positive effect of the changes in total feed intake (TFI), and feed cost on body weight (BW). Broiler group fed 4% DA revealed a significant positive effect of the changes in TFI, and feed cost on BW. And a significant effect of changes in total cost (TC) on total return (TR). |
