Feed intake was fixedas 0.08 g DM/kg0.75 per day given in two daily equal rations.The mulberry leaf meal contained crude protein (N×6.25) 14.50and NDF 34.55% and 17.81 kjoule/g on dry matter basis respectively.There was no significant interaction (P > 0.05) betweenmulberry foliage meal and crude palm oil levels in anydigestibility index. Overall, digestibility indices were high. Increasinglevels of mulberry leaf meal in diet had a significant(P < 0.01) negative influence on DM, organic matter, NDF, Nand energy respectively, This same trend, although not significant(P > 0.05) was observed for increasing levels of crudepalm oil in the diet on digestibility indices of pigs. N and organicmatter digestibility of mulberry as determined by differencewere 43.65 and 64.65 % respectively, whereas digestibleenergy accounted for 9.41 kjoule/g DM. Digestible energy estimatedfor the crude palm oil was rather low 16.12 kjoule/gDM). It is suggested that mulberry leaf meal could be introducedup to 20% in diets for growing pigs with no deleteriousinfluence on total tract digestibility indices. The use of palm oilup to 9% can contribute to increase the energy density of thediet. Due to the relatively low digestibility of crude palm oil,methods should be investigated in order to improve its nutritivevalue 2006 artículo científico 0798-2259 https://www.redalyc.org/articulo.oa?id=95916110 en http://www.redalyc.org/revista.oa?id=959 Revista Científica application/pdf Universidad del Zulia Revista Científica (República Bolivariana de Venezuela) Num.1 Vol.XVI |
