Effect of garlic peel on haematological, biochemical and digestive enzyme activity in beluga juvenile (Huso huso)

Our study was concentrated on the effect of garlic peel on haematological parameters, biochemistry and digestive enzymes on beluga juvenile (Huso huso) with mean body weight of 18. 41 ± 0. 89 g after the feeding trial for 90 days. Garlic peel powder added with 0%, %0.5, %1, %1.5 and %2 of feed to basic sturgeon diet (49% protein and 14% lipid). ultimately, haematological parameters, biochemistry, digestive enzyme activity were evaluated. Results showed that the hemoglobin (Hb) was remarkably greater in the treatment fed garlic peel diet in comparison with the control (p<0.05), while others blood indices did not significant differences (p>0.05) between juveniles fed control and garlic peel supplementation diets. The group fed 1.5% garlic peel showed highly significant different in total protein (p<0.05). However, Glucose, triglyceride, total lipid, cholesterol, ALP and ALT were significantly decrease in the juvenile fish fed by the 1.5% garlic peel diet compare to the control (p<0.05).The fish treated with 1.5% garlic peel exhibited significantly increase in amylase, protease and lipase compare to the control (p<0.05), but trypsin, chymotrypsin and pepsin were not affected (p>0.05). These results indicated that garlic peel powder in 1.5% level, improved blood indices and digestive enzymes activity of beluga sturgeon.
