expression of saturation or intensity of the colour
attained and is expressed by the equation,
Cab = (a*2 + b*2)1/2 (Hunt 1977). Data were
analysed statistically using analysis of variance
(ANOVA) for feeding type (Steel & Torrie 1980). Significant
differences among means (P 0.05)
were ranked using Duncan’s new multiple range
tests. The results were presented as means SD
and significance was indicated when P 0.05.
