aFor each variable, no difference between divisions was observed; therefore, data was averaged across divisions.
bTP: plasma total protein; LAC: plasma lactate; CORT: cortisol; AST: plasma aspartate aminotransferase; TOC: plasma alpha-tocopherol; RET: plasma retinol; BC: plasma beta-carotene; GPx: erythrocyte glutathione peroxidase.
x,y,zWithin row, means with unlike superscripts differ (P < 0.05).
