The Effect of Different Levels of Fat Inclusion and Cereal Type on Digestibility Parameters for Growing Pigs

摘要

Fourteen pigs, with post-valve T-caecum cannulae, were randomized to seven diets (five by-product with increasing fat level and two cereal diets) using a three-period crossover design. Seven-day faecal collections were followed by two 12 h ileal collections using Ti02 as a marker. Significant increases in ileal digestibility (ID) of dry matter (DM) (4.7%), oil (18.9%) and energy (5.9%) and increases (NS) of ID for crude protein (CP) (3.2%) and neutral detergent fibre (5.6%) occurred with 10% fat compared with the basal diet. The barley- and maize-based diets resulted in higher overall digestibility of DM (9.3%), CP (6.4%) and energy (9.1%) and 46% less faeces (DM basis) than by-product diets.
