Feed Intake and Apparent Nutrient Digestibility of Growing Rabbits Fed Asystasia gangetica with Different Levels of Corn

Abstract

This study investigated the effect of different corn levels on intake and digestibility in rabbits. The rabbits were divided into four groups and given Asystasia gangetica ad libitum as a basal diet and supplemented with either 80 g (T1), 60 g (T2), 40 g (T3), or 0 g (T4) corn/head/day. Rabbits fed with the T4 diet demonstrated a higher intake/kg metabolic weight than the other treatments. Nevertheless, rabbits fed with T4 and T1 diets depicted the lowest and highest digestibility, respectively. In conclusion, apparent nutrient digestibility was significantly improved in growing rabbits following supplemental feeding with a diet containing 60-80 g of corn.
