The effect of biological treatment on chemical composition, digestibility and feeding values of cotton stalks and rice straw [electronic resource].

Includes references.

The present work was carried out to study the effect of incubated cotton stalks and rice straw with white-rot fungi growth (Pleurotus ostreatus) (P.O) on the digestibility (In vitro and in vivo) and feeding value of cotton stalks and rice straw. results showed that CP was Increased by 39.80% and 56,40% due to the growth of P.O on cotton stalks and rice straw, respectively, whereas CF was decreased by 42.55% and 53.54% for cotton stalks and rice straw, respectively. The In vitro dry matter (OM) digestibility of treated rice straw and cotton stalks was significantly increased (P < 0.05) by 30 and 23.2% respectively, while in vitro OM digestibility was increased (P < 0.05) by 37.7 and 36.4%, respectively. Compared with untreated materials, most of nutrient digestibility coefficients of rations contained treated materials were significantly higher (P < 0.05) than those contained untreated ones. Likewise, the feeding value as TON and OCP% was improved as a result of biological treatment. It could be concluded that biological treatment could be used successfully to enrich poor quality roughages and improved digestibility coefficients and feeding values of treated materials and helpful to eliminate environmental pollution.
