چکیده | ||
به منظور بررسی تأثیر سطوح متفاوت سیلیمارین (صفر، 100، و 200 میلیگرم در کیلوگرم جیره) بر عملکرد، خصوصیات لاشه، برخی فراسنجههای خونی، و وضعیت آنتیاکسیدانی جوجههای گوشتی از 120 قطعه جوجۀ گوشتی سویۀ راس 308 در سه تیمار با چهار تکرار و 10 قطعه جوجۀ گوشتی در هر تکرار در قالب طرح کاملاً تصادفی استفاده شد. نتایج آزمایش نشاندهندۀ آن است که استفاده از 200 میلیگرم سیلیمارین، وزن روزانه را در دورۀ آغازین افزایش و در کل دورۀ پرورش کاهش داد و ضریب تبدیل خوراک را در دورۀ آغازین، رشد، و کل دورۀ آزمایش افزایش داد (05/0P<). استفاده از سطوح 100 و 200 میلیگرم سیلیمارین در جیره، بهترتیب بازده لاشه و وزن نسبی سینه را افزایش داد (05/0P<). افزودن 200 میلیگرم سیلیمارین به جیره باعث افزایش معنیدار غلظت مالوندیآلدهید (05/0P <) و نسبت هتروفیل به لنفوسیت (01/0P<) و کاهش معنیدار فعالیت سوپراکسید دسموتاز (05/0P <) شد. براساس نتایج پژوهش حاضر، استفاده از سیلیمارین در جیرۀ جوجههای گوشتی در شرایط بدون تنش و بیماری، وزن نسبی لاشه و سینه را بهبود داد، ولی بر وضعیت اکسیداتیو پرنده اثری ندارد. | ||

چکیده [English] | ||
In order to investigate the effect of different levels of silymarin (0, 100 and 200 mg/kg diet) on performance, carcass characteristics, blood parameters and antioxidant status, 120 day-old chicks were assigned to 3 treatments with four replicates and 10 birds in each in a completely randomized design. Results showed supplementation of 200 mg silymarin significantly decreased the body weight gain (BWG) in starter (P<0.05) and whole period of experiment (P<0.01) and significantly increased feed conversion ratio at starter (P<0.05), grower (P<0.05) and total rearing periods (P<0.01). Also, addition of 100 mg silymarin significantly increased the carcass relative weight (P<0.01) and supplementation of 200 mg silymarin significantly increased the breast relative weight (P<0.05). Furthermore, 200 mg silymarin significantly increased the malondialdehyde and heterophil/ lymphocyte ratio and significantly decreased superoxide dismutase (P<0.05). These results showed that supplementation of silymarin in diet under normal condition, improved the carcass and breast relative weight, but no had effect on bird’s oxidative status. | ||
