¹ W_eggs: total weight of eggs laid; ² H_eggs: percentage of hatching of eggs laid; ³ RE: reproductive efficiency, ⁴ PE: efficiency of the product (percentage). Values with the same superscript letters within a column do not showed statistically significant differences by Tukey and Neuman-Keuls tests (p < 0.05).
