چکیده
پژوهش حاضر به‌منظور بررسی اثر تریپتوفان، ملاتونین و دی‌متیل گلایسین بر عملکرد رشد و کیفیت گوشت بلدرچینهای ژاپنی تغذیه‌شده با جیره‌های آلوده‌شده با سم آفلاتوکسین B1 انجام شد. در این آزمایش تعداد 680 قطعه بلدرچین ژاپنی از سن هفت تا 35 روزگی در 17 تیمار و چهار تکرار و در هر تکرار 10 قطعه بلدرچین ژاپنی با استفاده از طرح مرکب مرکزی مورداستفاده قرار گرفتند. عملکرد پرندگان به‌صورت هفتگی محاسبه و در انتهای آزمایش میزان مالون‌دی‌آلدهید گوشت اندازه گیری شد. نتایج نشان داد که تریپتوفان سبب افزایش معنیدار وزن بدن شد (p<0/05) و ملاتونین تأثیر افزایشی بر مصرف خوراک داشت (p<0/05). اثر اصلی تریپتوفان و هم‌چنین اثر متقابل تریپتوفان و دی‌متیل گلایسین میزان مالون‌دی‌آلدهید گوشت را کاهش داد (p<0/05). نتایج مطالعه حاضر نشان داد تریپتوفان و دهندههای گروه متیل دارای ظرفیت آنتیاکسیدانی مناسبی برای کاهش مسمومیت ناشی از آفلاتوکسین B1 بر عملکرد رشد و میزان مالون‌دی‌آلدهید گوشت هستند و استفاده از این مکملها در جیره غذایی بلدرچین ژاپنی مطلوب به نظر میرسد.

چکیده [English]
The experiment was carried out to investigate the effect of tryptophan, melatonin and dimethylglycine on the growth performance and meat quality of Japanese quails fed diets contaminated with aflatoxin B1 toxin. In this experiment, 680 Japanese quail from 7 to 35 days of age were allotted to 17 treatments and 4 replicates (10 birds per replication), and trial performed using a central composite design. The performance of birds was calculated on a weekly basis and at the end of the experiment; and the amount of malondialdehyde in meat was determined. Results showed that tryptophan increase weight gain and melatonin had an increased effect on feed intake (P < 0.05). The effect of tryptophan and as well as the interaction of tryptophan and dimethylglycine reduced the amount of malondialdehyde in meat (P < 0.05). The results obtained from this research state that dietary supplementation with tryptophan and methyl group donors have good antioxidant capacity to reduce aflatoxin B1 poisoning on growth performance and malondialdehyde content of meat, and the use of these supplements in the diet of Japanese quails seems desirable.
