Abstract


Gastrointestinal morphology indices in 24 White New Zealand rabbits were examined, with an average weight of 2.0 kg, fattened ad libitum and randomly with varying levels (0.15 and 30 %) of moringa (Moringa oleifera) forage meal. There was not significant effect (P > 0.05) of the treatment on the relative content of fresh digesta (average, 116.7 g/kg live weight). The weight of the entire empty digestive tract seemed to slightly decrease in a significant way (R2, 0.884, P <0.040) with the introduction of moringa forage in the food (80.6, 79.8 and 76.1 g/kg live weight). There was not significant interdependence (P> 0.05) between the relative weight of fresh digesta and the tract of the evaluated rabbits. The moringa forage determined a longer small intestine (P <0.05) with a lower linear density (P> 0.10). It is concluded that the use of moringa forage meal to fatten rabbits can determine few changes in the gastrointestinal macroarchitecture of the animals.
