  1. Treatments whose mean ± SD are followed by distinct lower case letters at the same column differ significantly (p < 0.0001). Days whose mean ± SD are followed by distinct upper case letters at the same line differ significantly (p < 0.0001). There was interaction between the factors (p < 0.0001).
