Determination of Chemical Composition, Physical Characteristics and Nutritive Value of Treated Walnut Hull by Neurospora Sitophila through Nylon Bag and Gas Production Methods
Abstract
In this research, chemical composition, gas production characteristics, effective degradability and nutritive value index (NVI) of DM and CP by in situ method of treated walnut hull by Nurospora Sitophila were studied. Three fistulated Kermani ram were used for determination of Walnut hull degradability. Data were analysed using completely randomize design. By processing walnut hull with Neurospora Sitophila, water holding capacity and total content of tannin and phenol decreased significantly, while the insoluble ash increased significantly. Processing had no significant effect on degradability parameters and NVI of dry matter and crude protein. Gas production volume in untreated Walnut hull in times 6, 12 and 24 hours increased significantly with comparison to the treated Walnut hull. Generally, processing of walnut hull with Nurospora Sitophila had no significant effect on nutritive value of this feedstuff.
