Growth performance of native goats fed diets containing different levels of energy

Castrated male goats (n = 40) of the Moxotó (n = 20) and Canindé (n = 20) breeds with an average weight of 15.3 kg were studied to determine intake, nutrient digestibility and weight gain for two diets with different energy levels. The experiment utilized a 2 × 2 factorial arrangement (two breeds and two diets), in which goats were randomly allocated. A diet of low energy density and a forage:concentrate ratio of 70:30 was utilized along with a diet of high energy density and a forage:concentrate ratio of 35:64. To determine the nutrient intake and digestibility, at the end of the experimen...
