Studies on the Cell Wall Digestibility in Pigs Fed Leucaena (Leucaena leucophala (Lam.) de Wit) Leaf Meal

Six crossbred castrate male pigs weighing on average 55 kg each were randomly allocated to 3 diets according to a duplicate 3×3 Latin square design to study digestion characteristics of cell wall fractions as determined by 0, 10 and 20% sun-dried leucaena (Leucaena leucocephala Lam. de Wit) Leaf Meal (LM) in diets based on sugar cane molasses type B and soybean meal. A significant (p<0.01) decrease in lignin and cell content (1-NDF) digestibility was observed by increasing the level of LM in the diet. There was no treatment effect on digestibility of crude fibre and other detergent fractions of fibre. A significant interdependence was found between faecal fresh material output and WHC (p<0.001, R = 0.896). It could be suggested that a 2 moderate increase in LM up to 20% in the diet, should not determine a marked, deleterious effect on fibrous fraction digestibility as measured at the rectal site of growing pigs.Seis cerdos machos machos castrados cruzados que pesaban en promedio 55 kg cada uno fueron asignados aleatoriamente a 3 dietas De acuerdo con un duplicado 3 × 3 de diseño cuadrado latino para estudiar las características de la digestión de las fracciones de la pared celular como Determinada por 0, 10 y 20% de leucaena secada al sol (Leucaena leucocephala Lam. De Wit) en dietas A base de melaza de caña de azúcar tipo B y harina de soja. Una disminución significativa (p <0,01) en lignina y células (1-NDF) se observó aumentando el nivel de LM en la dieta. No hubo tratamiento Efecto sobre la digestibilidad de la fibra bruta y otras fracciones detergentes de fibra. Una interdependencia significativa fue Encontrado entre la producción de material fresco fecal y WHC (p
