en hematology hematology كاربردي Applicable <div style="text-align: justify;">Our study was concentrated on the effect of garlic peel on haematological parameters, biochemistry and digestive enzymes on beluga juvenile (<em>Huso huso</em>) with mean body weight of 18. 41 &plusmn; 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&nbsp; 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.<br> &nbsp;</div> Garlic peel, Blood indices, Digestive enzyme, Huso huso 13 28 http://ijaah.ir/browse.php?a_code=A-10-173-1&slc_lang=en&sid=1 Hا Chitsaz حسین چیت ساز chitsaz2@gmail.com 10031947532846001792 10031947532846001792 No Department of Fisheries, Azadshahr Branch, Islamic Azad University, Azadshahr, Iran گروه شیلات، واحد آزادشهر، دانشگاه آزاد اسلامی، آزادشهر، ایران H Oraji حسین اورجی hoseinoraji@yahoo.com 10031947532846001793 10031947532846001793 Yes Department of fisheries, Faculty of Animal Sciences and Fisheries, Sari Agricultural Sciences and Natural Resources University (SANRU), Sari, Iran گروه شیلات، دانشگاه علوم کشاورزی و منابع طبیعی ساری، ساری، ایران A Keramat Amirkolaei عبدالصمد کرامت امیرکلایی amirkola@yahoo.com 10031947532846001794 10031947532846001794 No Department of fisheries, Faculty of Animal Sciences and Fisheries, Sari Agricultural Sciences and Natural Resources University (SANRU), Sari, Iran گروه شیلات، دانشگاه علوم کشاورزی و منابع طبیعی ساری، ساری، ایران R Akrami رضا اکرمی akrami.aqua@gmail.com 10031947532846001795 10031947532846001795 No Department of Fisheries, Azadshahr Branch, Islamic Azad University, Azadshahr, Iran گروه شیلات، واحد آزادشهر، دانشگاه آزاد اسلامی، آزادشهر، ایران
