TI  - Determining the In Situ Ruminal Degradability of Some Nutrients of Wheat Straw Using Some White Rot Fungi Species
AB  - The Phanerochaete chrysosporium (PC) and Pleurotus eryngii (PE)  were observed for their potential to increase the in situ dry matter (DM) and crude protein (CP) degradability of wheat straw. The wheat straw samples were inoculated with the PC and PE fungi (10% weight/volum) and incubated under solid state fermentation conditions at 30 ◦C for 30 days to determine their in-situ degradability and chemical composition. In situ ruminal degradability was determined by using four ruminal cannulated Holstein bulls (approximately 400 kg BW) fed on a diet a concentrate-to-roughage ratio of 45:55 (dry matter (DM) basis). The samples were incubated in nylon bags for 0, 4, 8, 16, 24, 48, 72 and 96 h in the rumen. The results showed that increased in situ ruminal degradation of DM and CP in PC and PE groups in comparison to the control group (P < 0.01). The wheat straw incubated with PC had the greatest in situ DM degradability after incubation for 24 h (P < 0.01). The inoculation of PC and PE increased in situ ruminal crude protein (CP) degradation (P < 0.01) in comparison to the other treatments. As a result, the fungal inoculants and urea treatment increased the degradability of DM and CP in wheat straw.
