The objective of this study was to evaluate the effects of sex and supplementing Chloris gayana hay with either Lablab purpureus or Vigna unguiculata on growth, volatile fatty acid (VFA) production and apparent nutrient digestibility. Eighteen goats, one-year-old, of average live weight 14.13±0.24 kg was apportioned in a completely randomized design to three diets which were iso-nitrogenous and iso-energetic. Animals were housed individually with 6 animals per treatment composed of three males and three females. Total DM intake was higher (P< 0.05) in T 2 (694.8 g/head/day) and T 3 (688.1 g/head/day) compared to T 1 (607.8 g/head day). The goats gained at a rate of 35.0 g/d; 45.0 g/d and 38.3 g/d for T 1, T 2, and T 3, respectively. Goats on T 2 showed a non-significantly higher (P> 0.05) growth rate exhibiting total gain of 2.68 kg compared to 2.08 kg and 2.33 kg for T 1 and T 3, respectively. Animals on T 1 (19.16) exhibited a significantly lower FCR (P< 0.05) than T 2 (15.44) and T 3 (18.11). Apparent DM digestibility were significantly different (P< 0. 05) among treatment diets. Sex significantly influenced DM, ADF and NDF digestibilities (P< 0.05). There were no significant (P> 0.05) differences in individual VFA molar concentrations among treatment diets and due to sex for acetate, propionate, valerate, iso-butyrate and iso-valerate. However, diets significantly influenced butyrate concentration (P< 0.05) with 0.25, 0.95 and 0.25 mM for T 1, T 2 and T 3, respectively. The percentage molar concentration for acetate was 75%, 73%, and 77% while the propionate concentration was 12%, 8% and 10.7% for T 1, T 2, and T 3, respectively. The acetate to propionate ratio was 6.2, 9.12 and 7.15 for T 1, T 2, and T 3, respectively. In conclusion, the study demonstrated that Cowpea and Lablab forages can support growth in goats at the same level of CP as in commercial pellets.
