Statistical analysis were based on anova and Tukey tests.

Alphabetic superindices (a, b, c) indicate statistically significant inter-group differences, when comparing treatment kind; numeric superindices (1, 2, 3) indicate statistically differences inter-group differences, when comparing stages of post-treatment period. Significant P ≤ 0.05. Comparisons among different postnatal ages where not executed.
