The Effects Of Treating Rice Straw Or Bagasse Treatment With Steam And Trichoderma Reesei On Their Chemical Composition And Nutritional Value For Baladi Goats

Abstract

The effect of steaming and fungal treatment of rice straw and bagasse on their chemical composition was studied. Results of reduced sugars, degree of saccharification, dissolved material during hydrolysis, xylan and uronic acid peaked at 6 hr. from treatment. Meanwhile, the percentage of enzyme absorbed peaked at 4 hr. from treatment. Twenty Baladi goats averaged 15.1+ 1.1kg were distributed randomly on four groups. The treatment of steaming followed by Trichoderma reesei for 35 days decreased (P<0.05) the CP, CF, EE, NDF, ADF, cellulose and hemicellulose contents of rice straw and bagasse. In vitro rate of degradation and in vitro neutral detergent fiber digestibility increased (p<0.05) in treated rice straw and bagasse than control treatments. Digestion coefficients for DM, OM, CF, NDF, hemicellulose and Cellulose and apparent nitrogen retention increased (P<0.05) in goats fed treated rice straw and bagasse. Animals fed treated rice straw had higher (P<0.05) CP digestibility. Average daily gain of goats fed treated rice straw and bagasse were higher (p<0.01) than those of control goats. Concentrate mixture, and roughage intake increased (P<0.05) for goats fed treated rice straw and bagasse. Treatments improved the dry matter intake and feed conversion (TDN and DCP, g/g gain) which increased (P<0.01) in goats fed treated rice straw and bagasse. Steam and fungal treatment improve the animal performance but type of roughage should be considered
