assessment of blood factors in flower horn fishes fed cow skin hydrolyze

the present study was designed to evaluate blood factors in the flower horn fishes that were fed with different levels of hydrolyzed cow skin. 216 fishes with average weight and length, respectively, 0.95 ± 0.2 (g) and 3.7 ± 0.2 (cm) during the 100-days period of experiment were fed. results showed that in the treatments fed diets containing 40% hydrolyzed cow skin, number of rbc with mean (2.5 ± 0.33) ×106 , percent of htc (25 ±1.72) and hemoglobin (8.5 ±1.66) grams per deciliter, was increased compared to controls (p0.05). the highest values of mcv factor with average (1.04 ±0.32) was related to treatment %100 (p< 0.05) and the lowest values of it with average (0.96 ±0.52) was related to treatment %60 (p< 0.05). about mch, the highest measured values with average (3.45 ±0.72), was related to the control diet and the lowest values of it with average (3.36 ±0.24) was related to treatment %20 (p
