effect of (pleurotus florida) fungi on chemical composition and rumen degradability of wheat and barley straw

this study was conducted to investigate the effect of biological treatment withpleurotus floridafungi on chemical composition and rumen dry matter (dm) and organic matter (om) degradability of wheat and barley straw. wheat and barley straw were collected from golestan province of iran and after pasteurization mixed with fungi spawn (than 5% by weight). after 21 days samples were dried in oven (60 ˚c) in order to stop fungi growth. dry matter (dm) and organic matter (om) degradation determined using nylon bag technique with two fistulated dalagh rams and sampleswereincubated at zero to 96 hours in rumen. fungi cultivation significantly decreased the amount of dry matter (dm), neutral detergent fiber (ndf) and acid detergent fiber (adf) in wheat and barley straw (p
