Effect of Manure Application on Herbage Yield, Nutritive Value and Performance of Wad Sheep Fed Panicum maximum

摘要

Effect of types of manure on herbage yield, nutritive value and performance of WAD Sheep fed native Panicum maximum was investigated. The experiment was laid out in a randomized complete block design with each plot replicated thrice. Poultry manure and sheep - goat manure were applied through broadcasting to an established Panicum maximum stand to supply 200kgN/ha and 0kgN/ha (control). Grass herbage harvested from experiment plot were fed as sole diets to West African dwarf sheep to determine feed intake (g/h/d), nutrient digestibility (%) and weight gain (g/h/d). Results showed that Panicum maximum fertilized with poultry manure produced (P<0.05) higher values for biomass yield, number of tillers, tiller height, leaf length and leaf width. The chemical composition of Panicum maximum fertilized with poultry manure produced (P<0.05) higher CP and GE compared to sheep-goat manure. Similar trend of result was observed on mineral composition of Panicum maximum fertilized with poultry manure produced (P<0.05) higher values for P, K, Ca, Mg, Fe, Zn and Cu compared to sheep-goat manure. The feed intake (g/h/d), nutrient digestibility (%) and weight gain of the animals fed Panicum maximum fertilized with poultry manure produced higher values compared to its counterpart. It was concluded based on data obtained from this study that poultry manure application will promote higher yield and nutritive value for the Panicum maximum. Animals fed with this as sole diet and as short feeding regime experienced high weight gain. Keywords: Poultry manure, sheep - goat manure, herbage yield, Panicum maximum, WAD Sheep
