Replacement effects of Panicum maximum with Ficus polita on performance of West African dwarf goats.
The replacement value of Ficus polita for Panicum maximum was evaluated on 32 female post-weaned West African dwarfs goats. Ficus polita was fed with P. maximum at different proportions of 0:90 (F. polita:P. maximum), 30:60, 60:30 and 90:0 constituting diets 1, 2, 3 and 4 respectively. Each diet was supplemented with 10% cassava peels. Dry matter intake per kg metabolic weight of goats was not significantly (p> 0.05) influenced by the dietary treatments. However, crude protein intake per kg metabolic weight was higher (p < 0.05) in animals fed 60% and 90%F. polita than those fed sole P. maximum diet. Daily weight gain of goats fed diet 3 (60%F. polita) was higher (p < 0.05) (27.3 g) than those fed diets 4 (18.9 g), 2 (20.8 g) and the control (6.6 g). Dry matter (DM), organic matter, crude protein (CP) and neutral detergent fibre digestibilities were higher (p < 0.05) in goats fed 60%F. polita than those fed other diets, except for DM digestibility which was statistically similar to diets 2 and 4 but higher than those fed diet 1 without F. polita. Organic matter and CP digestibility were highest (72.0 and 65.7% respectively) in animals fed 60%F. polita. Nitrogen retention of goats fed 60%F. polita (diet 3) was higher (p < 0.05) than that obtained with other diets. The results suggest that feeding combination of F. polita and P. maximum at ratio 60:30 respectively has associative effects that can enhance growth rate, feed intake, nutrients digestibility and nitrogen utilization for goat production during dry season in the tropics.
