RSS, ratio of sum of spots areas on the whole eggshell to sum area of the whole eggshell.
RSS1 are initial value; RSS2 are conversed values and the formula: Y Arc sin ((Sqrt)X) Where X are values of RSS1, and Y are values of RSS2.; P1 and P2 are calculated by Shapiro-Wilk test, where P>0.05 suggesting it conforms to the normally distributed and P < 0.05 is not.
a,b,c,d
Among 10 groups mean without a common superscript differ (P < 0.05).
