Abstract

An experiment was conducted to compare the yield, composition and nutrient digestibility of gama (Tripsacum dactyloides), oat (Avena sativa) and sorghum (Sorghum bicolor) forages. Three fodders were cultivated and a metabolism trial was conducted with 3 indigenous sheep in a 3 × 3 Latin Square Design (LSD) for determination of nutrient digestibility. The fresh yield of gama was higher (P<0.05) than that of oat and sorghum. The yield of DM in gama and sorghum was similar and significantly higher (P<0.01) than oat. No significant differences (P>0.05) were observed in DM, OM, CP, NDF and ADF contents among the gama, oat and sorghum forages. The average DM and OM intake in sheep fed sorghum was higher (P<0.05) than that of oat or gama. Sheep fed sorghum or oat showed significantly (P<0.01) higher CP intake than gama. Average NDF and ADF intake was higher (P<0.05) in sheep fed sorghum followed by oat or gama, respectively. The DM digestibility of different forages was found non-significant (P>0.05). The OM digestibility of sorghum was found to be higher (P<0.05) compared to oat or gama. Digestibility of CP was significant (P<0.01) higher sorghum than oat (37 %) or gama (36 %). Higher NDF and ADF digestibility (P<0.05) were found in sorghum and oat, respectively than gama. It was concluded that sorghum (Sorghum bicolor) is better than gama (Tripsacum dactyloides) and oat (Avena sativa) forages.
