چکیده

هدف از این مطالعه بررسی نقش افزودنی میکروبی تولید کننده اسید لاکتیک و همچنین جاذب های مختلف در کاهش پس آب و بهبود ویژگی های شیمیایی و تخمیری سیلاژ تفاله چغندرقند تازه بود. در آزمایش اول تفاله چغندر بصورت خالص یا به صورت مخلوط شده با 5 درصد کاه یا 5 درصد پیت بمدت 90 روز سیلو شد. در آزمایش دوم تفاله چغندر با افزودنی میکروبی، پیت و یا مخلوط آنها سیلو شد. غلظت ماده خشک و دیواره سلولی در سیلاژهایی که کاه یا پیت دریافت کرده بودند بیشتر از تیمار شاهد بوده و پس آب تولیدی کاهش پیدا کرد (01/0P
