Abstract

Context: Sustainable utilization of abundant forage grass species in Nigeria is very crucial in grasscutter domestication programme.

Objective: This study evaluates comparative effects of Elephant grass (Pennisetum purpureum) and Gamba grass (Andropogon gayanus) parts on growth performance of captive-bred juvenile male grasscutters.

Materials and Methods: The study was conducted inside Grasscutter Domestication Unit of Federal College of Wildlife Management, New Bussa, Niger State, Nigeria. The experimental animal comprised of twenty-four juvenile males (JM) with mean live-weight of 410±2.11g fed four basal dietary treatment combinations: Elephant grass stem (EGS), Elephant Grass Leaf (EGL), Gamba Grass Stem (GGS) and Gamba Grass Leaf (GGL) in a 2 x 2 factorial arrangement for 120 days to obtain data which includes feed intake (FI), feed conversion ratio (FCR), weight gain (WG), nutrient digestibilities of dry matter (DM) and crude fibre (CF).

Results: Average daily feed intake (FI) in JM was significantly (p<0.05) higher in experimental animals fed with GGS (107.23g/d) and EGS (106.21g/d) relative to GGL (105.89g/d) and EGL (105.14g/d). EGL exhibited higher (4.45g/d) WG and lowest (23.69) FCR. JM fed EGL recorded highest digestibility of DM (85.64%) and CF (83.84%), respectively. Grass species and parts interaction showed significant variation (p<0.05) on FI, DM and CF of the animals when fed EGL.

Conclusion: It was evident that EGL was maximally utilized by captive-bred juvenile male grasscutters for growth performance hence, feeding of captive male grass cutters with EGL as basal food for table meat production is recommended.
