<b>Manioc silage associated with energy sources on feeding goats: intake and digestibility</b> - DOI: 10.4025/actascianimsci.v31i3.5228

Abstract

In order to evaluate the diet combination of manioc silage with different energy sources, intake and apparent digestibility were determined in feedlot goats. The diets consisted of 54% manioc silage and 46% energy concentrates: corn meal (Zea mays) (T1), cassava meal (Manihot esculenta Crantz) enriched with 1.8% urea (T2), and cactus meal (Opuntia ficus indica), enriched with 1.1% of urea (T3). Fifteen male goats were mixed-breed, initially weighting 21.0 kg, distributed in randomized blocks with three treatments and five repetitions. The greatest intake were observed for the treatments T3 and T1, with values for DM of 96.92 and 67.26 g kg^{-0, 75} days^-1; CP 157.72 and 78.54 g day^-1 and TDN 593.29 and 515.35 g day^-1 and diet composed of manioc silage with cassava meal that had lower intakes with values for DM of 52.78 g kg^{-0, 75} days^-1 and TDN 347.10 g day^-1. The digestibility of DM, CP, NDF were 70.74; 54.66 and 58.08; 59.58; 58.75 and 47.04; 62.49; 64.24; 51.60%, respectively, for treatments T1, T2 and T3. The results obtained for intake and for the apparent nutrient digestibility reveal a favorable potential for the combination of manioc silage with energy sources available regionally.
