| چکیده | ||
| این تحقیق با هدف ساخت و بررسی کارایی روغن بادام زمینی ید دار شده در پیشگیری از عوارض کمبود ید در گوسفند انجام شد. ابتدا اتیل استر ید دار شده اسیدهای چرب روغن بادام زمینی ساخته شد سپس یک گله گوسفند داشتی با سابقه کمبود ید انتخاب گردید و در این گله، تعداد 30 رأس میش جوان از توده نژاد فراهانی با وزن بدن مشابه (4 ± 42 کیلوگرم) به‌صورت تصادفی به سه گروه شامل شاهد و دو گروه آزمایشی (سه تیمار و 10 تکرار) تقسیم شدند. گروه آزمایشی اول، مقدار 390 میلی گرم ید به شکل اتیل استر اسیدهای چرب روغن بادام زمینی و گروه آزمایشی دوم، همین مقدار ید را از مکمل مشابه خارجی با نام تجارتی دپودین (®Depodine ) در اواخر آبستنی در انتهای فصل زمستان دریافت کردند. مدت زمان اجرای آزمایش سه ماه بود که طی آن غلظت ید معدنی سرم و هورمون‌های تیروئیدی شامل T3، T4 در شروع آزمایش و ماهیانه در گروه‌های آزمایشی اندازه‌گیری و مقایسه شد. هر دو مکمل ید باعث افزایش معنی‌دار غلظت ید معدنی سرم خون در گروه‌های آزمایشی نسبت به گروه شاهد در هر سه ماه نمونه‌برداری شدند ((01/0< P)و هر دو مکمل باعث افزایش تولید و غلظت هورمون‌های T4 و T3 در کل دوره آزمایش نسبت به مقدار پایه و گروه شاهد گردیدند ((01/0< P). نتایج نشان داد که ساخت این هورمون‌ها تحت تأثیر کمبود ید قرار داشته‌اند و مکمل تهیه شده در پیشگیری از عوارض کمبود ید در دام موثر و دارای اثر مشابهی با نمونه خارجی می‌باشد. | ||

| This research was conducted to produce and study the effect of iodinated peanut oil on preventing iodine deficiency disorders (IDD) in sheep. Iodinated fatty acid ethyl esters prepared from peanut oil (IFAEEpo). Thirty Farahani ewes (average body weight ± standard deviation = 42±4 kg) with a history of iodine deficiency were divided into three groups, including one control and two treatment groups. The treatment groups received 390 mg iodine by intramuscular injection of IFAEEpo (n = 10) or Depodine® (n = 10), respectively in late gestation at the end of winter. The duration of the study was three months, and serum iodine and thyrotropin-stimulating hormone (TSH), T3 and T4 concentrations were determined at baseline and every 30-day intervals over a period of three months. The serum iodine concentration of the test animals was 15.14 μg/litre at the beginning of the trial and thus in the deficiency range. Both iodine supplements caused a significant increase in serum iodine concentration in the experimental groups compared to the control group in all three months of sampling (P < 0.01), and both supplements increased the production and concentration of T4 and T3 hormones in the entire experimental period. The increase in serum mineral iodine concentration and thyroid hormones after iodine supplementation showed that the production of these hormones was affected by iodine deficiency and that the supplement produced was effective in preventing the iodine deficiency disorders in livestock and had a similar effect to the foreign ones. | ||
