Animal production in tropical regions is commonly limited by the low crude protein content and digestibility of pastures, particularly during the dry season. The objective of the present study was to evaluate the effect of including Enterolobium cyclocarpum leaves (ECL) (0%, 15% and 30%) in diets as a partial replacement for lucerne on dry-matter intake (DMI), weight gain and nitrogen (N) balance in growing Saanen goats (12.6 ± 3.2 kg at 3 months of age) and the digestibility of the diet. Daily weight gain, DMI and digestibility were analysed in a 3 × 3 Latin square design replicated three times. The inclusion of ECL did not affect daily weight gain or DMI (P > 0.05). There were no significant (P > 0.05) differences for N intake among the diets, but the inclusion of 30% ECL significantly (P = 0.01) increased N excreted in faeces. These results suggest that ECL can be used as a partial substitute of lucerne in diets for growing goats, without affecting animal performance.
