چکیده

تأثیر سطوح مختلف کافور بر عملکرد، وزن اندام‌های داخلی، هورمون­های تیروئیدی و تستوسترون، جمعیت باکتریایی روده و فساد اکسیداتیو گوشت با استفاده از تعداد 200 قطعه بلدرچین، در قالب طرح بلوک­های کامل تصادفی با پنج تیمار و چهار تکرار به مدت شش هفته بررسی شد. تیمارها شامل سطوح صفر، 5/62، 125، 250 و ppm 500 کافور حل شده در روغن سویا بودند. در 42 روزگی از  بلدرچین­ها خون‌گیری به عمل آمد و سپس کشتار شدند. اثر کافور بر وزن بدن، مصرف خوراک، ضریب تبدیل، وزن لاشه و اندام­های درونی و غلظت هورمون­های تیروئیدی معنی­دار نبود. افزودن کافور به جیره سبب افزایش خطی هورمون تستوسترون در بلدرچین­های نر شد (05/0>P). تغذیه جیره­های حاوی کافور جمعیت باکتری­های هوازی و کلی­فرم­های روده را کاهش و جمعیت باکتری­های اسید لاکتیک و باکتری­های اسپورزا را افزایش داد (05/0>P). همچنین، با افزودن کافور به جیره در مقدار MDA گوشت نیز یک رفتار دوگانه مشاهده شد، به­طوری‌که دوزهای 5/62، 125 و  ppm250 کافور سبب افزایش مقدار MDA گوشت گردید (05/0>P). بنابراین، طبق نتایج حاصل به­نظر می­رسد داروی گیاهی کافور می­تواند بر هورمون تستوسترون و کیفیت گوشت تأثیر مثبتی داشته باشد. از این­رو پیشنهاد می­شود که کافور جهت ارتقاء و بهبود عملکرد تولید­مثلی در نرها استفاده شود.

چکیده [English]

This study was conducted to evaluate the effect of camphor levels on performance, organ weight, testosterone and thyroid hormones, intestinal selective bacteria, and meat peroxidation of Japanese quail. Two-hundred 1-d chicks were allocated in 20 cages with five treatments and four replicates (10 chicks per each cage) using complete randomized block design. Treatments were including: 0, 62.5, 125, 250, and 500 ppm camphor which dissolved in soybean oil. Blood sample was taken then quails were slaughtered at 42-d of age. Results revealed camphor unaffected the carcass and organs weight. Also feed conversion ratio, feed intake, live body weight, and thyroid hormones unaffected by using camphor supplementation in the diet. Results showed that camphor could enhance libido by increasing the production and secretion of testosterone (P< 0.05). Dietary camphor had a significant effect on the intestinal microbial population, so that could reduce the aerobic bacteria and coliforms, whereas increased the lactic acid bacteria and spore former bacteria (P< 0.05). Meat malondialdehyde level has been also changed significantly in both sexes by camphor dietary supplementation, which increased by using 62.5, 125, and 250 ppm camphor (P< 0.05). According to the current results, using camphor is recommendable for successfully reproduction in male birds.
