Extract

By-product-based diets generally contain lower levels of energy than cereal-based diets due to higher levels of fibre (Bakker et al., 1995). Supplementation with oil is a common method of improving the digestible energy content of by-product-based diets and it has been reported that this practice may also improve energy digestibility. However, the results of McCann et al., (2004) suggested that the method of oil application to finishing pig diets may affect the digestibility of dietary nutrients. The aim of this experiment was to compare apparent digestibility coefficients determined in finishing pigs offered either by-product based diets or cereal-based diets, with and without vegetable oil blend supplementation applied using two different methods (either directly incorporated into the pellet (IN) or sprayed (SP) on after pelleting).
