چکیده

تأثیر عصاره شیرین بیان، پروبیوتیک، ضد قارچ و بیوچار بر عملکرد جوجه های گوشتی تغذیه شده با خوراک آلوده به آفلاتوکسین B1 با استفاده از 350 قطعه جوجه گوشتی سویه راس در قالب طرح کاملاً تصادفی، با هفت تیمار (شاهد منفی (جیره پایه بدون آفلاتوکسین و ماده افزودنی)، شاهد مثبت (جیره پایه حاوی یک میلی گرم آفلاتوکسین و بدون ماده افزودنی) و پنج گروه دیگر شامل جیره پایه دارای یک میلی گرم آفلاتوکسین همراه با سه و شش گرم در کیلوگرم عصاره شیرین‌ بیان، 0/5 گرم پروبیوتیک پروتکسین، 0/5گرم ضد قارچ آگراباند و 10 گرم توکسین بایندر بیوچار کودمرغی) و پنج تکرار (10 قطعه) بررسی شد. جیره شاهد مثبت وزن بدن و وزن نسبی سینه جوجه های گوشتی را کاهش و ضریب تبدیل غذایی و درصد چربی بطنی را افزایش داد (0/05 > P). جیره های شاهد منفی، سه گرم عصاره شیرین‏ بیان و بیوچار در دوره رشد، و جیره های شاهد منفی و سه گرم عصاره شیرین بیان در کل دوره پرورش افزایش وزن بالاتر و ضریب تبدیل خوراک کمتری نسبت به سایر تیمارها داشتند (0/05 > P). بالاترین وزن نسبی سینه و بیشترین درصد پروتئین ران به ترتیب در جیره های حاوی پروبیوتیک و مکمل بیوچار مشاهده شد (0/05 >P ). بالاترین سطح پروتئین سرم خون متعلق به جیره حاوی سه گرم عصاره شیرین بیان و شاهد و پایین ترین سطح اسید اوریک خون متعلق به جیره شاهد، ضد قارچ، بیوچار و شش گرم عصاره شیرین بیان بود (0/05 >P ). به‏ طور کلی عصاره شیرین بیان و بیوچار کود مرغی قادر به کاهش اثرات منفی آفلاتوکسین B1 بر عملکرد جوجه های گوشتی هستند.

چکیده [English]

Using 350 Ross broiler chickens, the effect of licorice extract (LE), probiotic, antifungal and boiler litter biochar on performance of broiler chickens fed aflatoxin B1 contaminated diet in a completely randomized design with 7 treatment (negative control (basal diet without aflatoxin and additives), positive control (basal diet + 1 mg aflatoxin B1 and without additives) and 5 other treatments were positive control with LE (3 and 6 g/kg), Protexin probiotic (0.5 gr), Agrabond (0.5 gr/kg) and biochar toxin binder (10 g/kg)) and 5 replicates (10 birds in each replicate) considered. The treatments were. The result showed that aflatoxin B1 lowered body weight gain and breast relative weight and increased FCR and abdominal fat of broilers (P < 0.05). Broilers fed negative control, 3 g/kg LE and biochar containing diets during the growing period and birds fed negative control and 3 g/kg LE during the entire period had higher BW and lower FCR as compared to other groups (P < 0.05). Negative control diet decreased breast relative weight and tight meat crude protein percent, while all of the additives led to improving these traits since the highest relative weight of breast and tight meat crude protein percent were observed in probiotic and biochar groups respectively (P < 0.05). The highest serum total protein was seen in broilers fed negative control and 3 g/kg LE diets while the lowest serum uric acid was observed in broilers fed negative control, 6 g/kg LE, Agrabond and biochar diets (P < 0.05). In conclusion, licorice extract and broiler litter biochar additives decreased adverse effects of aflatoxin B1 on broiler chickens performance.
