  1. At the end of the 5th and 10th week of the trial, 6–8 birds from each treatment were selected to obtain wing vein blood and harvest serum. The levels of E2, P, LH, and FSH in the serum were measured. The data in Table 6 different superscript letters indicate significant difference (P < 0.05); same superscript letters indicate no difference (P > 0.1), the same below
