Data represent mean ± SD, n = 10 (C, control; L, low enzyme concentration; H, high enzyme concentration; LA, low enzyme concentration with citric acid; HA, high enzyme concentration with citric acid). RBC, red blood cells; Hb, haemoglobin; PCV, packed cell volume; MCV, mean cell volume; MCHC, mean corpuscular haemoglobin concentration; MCH, mean cell haemoglobin; WBC, number of leukocytes. Significant differences (hierarchical ANOVA) are indicated by different indices, the same index (a) across all experimental diets indicating an overall significant effect of the treatment without the possibility of distinguishing between diets.
