چکیده

زمینه‌مطالعاتی: هورمون ملاتونین به عنوان هورمون فتوپریودیک نقش بسزایی در فعالیت تولیدمثلی حیوانات مزرعه‌ای، از جمله نریان دارد. هدف: این آزمایش به منظور بررسی تغییرات غلظت هورمون ملاتونین در سه رده سنی 2 تا 6، 6 تا 10 و 10 تا 14 سال، تحت فتوپریود طبیعی در منطقه دزفول بود. روش‌کار: خونگیری از ورید وداج 33 رأس نریان اصیل عرب، در فصول تابستان (تیرماه) و زمستان (دی‌ماه) سال 1391 انجام شد. غلظت هورمون ملاتونین با دستگاه HPLC اندازه‌گیری شد. مقایسه فراسنجه‌ مذکور بین فصول تابستان و زمستان توسط آزمون T و تفاوت آن‌ها در دو فصل، در سه رده سنی با تجزیه واریانس (ANOVA) ­یک‌طرفه و آزمون چند دامنه­ای دانکن با استفاده از برنامه نرم افزار SPSS مورد آنالیز قرار گرفت. نتایج: میانگین غلظت ملاتونین سرم خون بین فصول تابستان و زمستان دارای تفاوت آماری معنی‌داری نمی‌باشد (05/0P>). در هر دو فصل میانگین غلظت ملاتونین در نریان‌های 2 تا 6 ساله به صورت معنی‌داری بیشتر از 6 تا 10 و 10 تا 14 ساله‌ها بود (05/0P<). نتیجه‌گیری نهایی: نتایج نشان داد که در نریان عرب، فصل تأثیری بر غلظت ملاتونین سرم خون ندارد ولی با افزایش سن غلظت ملاتونین کاهش می‌یابد.
