Abstract :
در این آزمایش اثرات افزودن پساب تقطیری ملاس درجیره غذایی برعملکرد رشد، صفات لاشه، طول وعرض پرزهای روده جوجههای گوشتی بررسی شد. 400 قطعه جوجه گوشتی یکروزه راس 308 به طور تصادفی در بیست قفس قرار گرفتند. پساب تقطیری ملاس در سطوح 0 و 4 درصد به جیره آغازین و در سطوح 0 و 4 و 8 درصد به جیره رشد افزوده شد. میانگین افزایش وزن روزانه، میانگین خوراک مصرفی روزانه و ضریب تبدیل غذایی از 7 تا 42 روزگی محاسبه گردید. نتایج این آزمایش نشان داد، افزودن پساب تقطیری ملاس بر فراسنجههای رشد، طول و عرض پرز ژوژونوم و عمق کریپت و صفات لاشه معنیدار نبود و اثر منفی مشاهده نگردید (05/0P>). نتایج این مطالعه نشان داد که افزودن پساب تقطیری تا سطح 8 درصد به جیره غذایی جوجههای گوشتی تأثیر منفی بر فراسنجههای عملکردی جوجههای گوشتی نداشت.
