Influence of urea and chicken manure treatments on the nutritive values of sorghum husk

This study aimed to improve the nutritional value and digestibility of Sorghum Husk (SH) using urea and chicken manure treatments. SH was exposed to chemical (5% urea), (5 % urea and 10 % molasses) and biological (chicken manure 10 %) treatments. A study was performed to investigate the effects of the different treatments on chemical composition and in vitro dry matter digestibility (IVDMD), Metabolizable energy (ME), neutral detergent fiber (NDF), acid detergent fiber (ADF), acid detergent lignin (ADL), digestible energy (DE), digestibledry matter (DDM), relative feed value (RFV).The obtained data were subjected to analysis of variance (ANOVA) for a completely randomized design The results showed signification variation (P< 0.05) on the nutritive value among different treatments of sorghum husk. The highest value of CP (11.27%), NFE (51.42%), IVDMD, (69.16), DDM (49.07), RFV (59.51) and ME (12MJ/Kg) were found in chicken manure treatment, while the highest value of Ash (7.41 %), and EE (1.32). were obtained in urea treatment. the lowest value of CF (29.13%), NDF (76.62 %)and ADL (4.55), were recorded for chicken manure treatment, while the lowest value of ADF (44.17%) were obtained for untreated sample. It could be concluded that chicken manure improve the nutritive value of sorghum husk by increasing the crude protein and IVDMD and decreasing all fibre fraction.
