“…Table (4) showed that the addition of Azolla (4.5,9,13.5)% did not have a significant (P≤0.05) effect on the average body weight compared to control during the breeding weeks as well as in the sixth week, and it reached (3216.67.2993.33, 3110.00) gm, respectively, compared with (3033.33) gm, and this confirms the fact that Replacing the protein obtained from Azolla with the protein of the standard diet gave the same performance of the chicks, which was translated into body weight, and this was in line with the weight gain (Table 4), the relative growth of the chicks(Table 6), and the feed conversion factor (Table 8). These results were supported by the researcher and also [11,3,12,13], while it disagreed with [5,14,1,15,16,17,18], the researcher noted [19,4] . Table (5) showed that the addition of Azolla(4.5,9,13.5)% did not significantly affect the rate of weight gain compared to control during the different breeding period, as well as the total weight gain, which respectively amounted to (3169.17, 2935.67, 3062.33, 2987.33) g for the treatments, respectively, and this is in line with the performance of birds in the rate Body weight (Table 3), relative growth (Table 4) and conversion factor (Table 7) with an improvement in economic indicators (Index, production coefficient and productivity per square meter, Table 9).…”
