Abstract

Background: Camel and sheep have high disperse and tolerance in tropical regions. But different results of harsh condition tolerance ability of them have been reported. ObjectiveS: The objective of this study was to determine the heat stress tolerance in camel and sheep by evaluating changes in blood serum metabolites and to report and compare the serum biochemical profile of sheep and camel during long heat stress of warm summer. Methods: In this experiment, blood metabolites of camel and sheep were taken and compared with each other in four consecutive months during warm months (high summer). Results: There was a significant difference between the values of urea, glucose, total protein, albumin, phosphors, calcium, ALT, ALP, uric acid, cholesterol, triglyceride, total bilirubin, and LDH of sheep and camels. Overall urea, glucose, total protein, albumin, phosphors, and calcium values were significantly higher in camels compared to sheep (p<0.01). Oppositely, sheep had significant higher values for uric acid, cholesterol, triglyceride, total bilirubin, and LDH (p<0.01). However AST and creatinine were not significantly different between sheep and camels. ConclusionS: Sheep sensitivity to heat stress was appeared in increasing in uric acid, cholesterol, triglyceride, total bilirubin, and LDH values compared to camel; so as it might be told sheep had more lipolysis-pattern during heat stress; their high blood LDH and total bilirubin were signs of red blood cell rupture or liver damage; and significant higher blood uric acid value in sheep makes them susceptive to a kidney problem such as gout.

Abstract [Persian]

زمینه مطالعه:  شتر و گوسفند از مقاومت و گستردگی زیادی در مناطق خشک برخوردارند. اما نتایج متفاوتی از توانایی آنها در تحمل این شرایط گزارش شده است. هدف: هدف این آزمایش، بررسی تحمل استرس گرمایی در شتر و گوسفند به وسیله ارزیابی تغییرات متابولیت‌های سرم خون، گزارش و مقایسه پروفیل بیوشیمیایی سرم خون گوسفند و شتر در طول استرس گرمایی طولانی تابستان است. روش کار: در این آزمایش نمونه‌های خون گوسفند و شتر در چهار ماه متوالی اخذ و مورد مقایسه قرار گرفت. نتایج: تفاوت معنی‌داری بین مقادیر اوره، گلوکز، کل پروتئین، آلبومین، فسفر، کلسیم،آنزیم‌های آمینوترانسفراز، اسید اوریک، کلسترول، تری گلیسرید، کل بیلی روبین و لاکتات دهیدروژناز گوسفند و شتر مشاهده شد. بطورکلی اوره، گلوکز، کل پروتئین، آلبومین، فسفر، کلسیم به طور معنی‌داری در شتر بالاتر از گوسفند بود (0.01>p). برعکس گوسفندان به طور معنی‌داری مقادیر بالاتری از اسید اوریک، کلسترول، تری گلیسرید، کل بیلی روبین و لاکتات دهیدروژناز نشان دادند (0.01>p). با این وجود آنزیم‌های آمینوتراسفراز و کراتین دو حیوان تفاوتی با یکدیگر نشان نداد. نتیجه گیری نهایی: این نتایج نشان داد گوسفند به استرس گرمایی حساسیت بیشتری دارد که با افزایش اسید اوریک، کلسترول، تری گلیسرید، کل بیلی روب ین و لاکتات دهیدروژناز نمایان می‌شود. بطوریکه شاید بتوان گفت گوسفندان در طول استرس گرمایی الگوی متابولیسمی لیپولیز را دارند. بالابودن لاکتات دهیدروژناز و کل بیلی روبین نشانه تخریب گلبول قرمز یا آسیب کبدی می‌باشد. همچنین غلظت بالای اسید اوریک خون گوسفندان سبب حساسیت بیشتر آنها به آسیب‌های کلیوی مانند نقرس می‌شود.
