چکیده

اثر جایگزینی جلبک قهوه‌ای سارگاسوم (Sargassum ilicifolium) با آرد ماهی بر ساختار بافت روده ماهی سی باس آسیایی (Lates calcarifer) با وزن اولیه 1±29 گرم در قالب یک طرح کاملاً تصادفی با 4 تیمار و سه تکرار به مدت 6 هفته انجام گرفت. جیره‌های آزمایشی با استفاده از جیره شاهد و سه جیره حاوی جلبک سارگاسوم با جایگزینی در سطوح 3، 6 و 9 درصد آماده شد. نتایج بدست آمده نشان داد که در بین تیمارهای مختلف و گروه شاهد از نظر طول انتروسیت، عرض پرز و ضخامت عضله در بافت روده اختلاف معنی‌داری وجود ندارد (05/0<P). با این حال جایگزینی جلبک سارگاسوم در سطح 6 درصد اختلاف معنی‌‌داری را در طول پرز و سطح جذب پرز بافت روده نشان داد (05/0>P). در مجموع، با توجه به نتایج بدست آمده به نظر می‌رسد که استفاده از ماکروجلبک سارگاسوم در سطخ 6 درصد در جیره غذایی ماهی سی‌باس آسیایی تاثیر مثبت بر پارامترهای مورد مطالعه در بافت روده داشت.

چکیده [English]

The effect of replacement brown macroalgae (Sargassum ilicifolium) with fishmeal, intestinal tissue structure of Asian Lates calcarfer, with an initial weight of 29±1 g, in a completely randomized design with 4 treatments and three triplicates for 6 weeks was done. The experimental diets were prepared using a control diet and three diets including brown macroalgae with replacement at level 3, 6 and 9%. The obtained results indicated that there was no significant difference between enterocyte length, villi width and muscle thickness in intestinal tissue between different treatments and the control group (P>0.05). However, replacement of sargassum algae at the level of 6% on the villi length and villi uptake level of intestinal tissue showed a significant difference (P<0.05). According to the results, the use of sargassum macroalgae at the level of 6%, in the diet of Asian seabass, had a positive effect on studied parameters of intestinal tissue.
