Extract

Oil supplementation of by-product based diets is a common method of increasing the energy content of pig diets to levels equivalent to those of cereal-based diets (Overland et al 1999). However, by-product based diets supplemented with oil have been reported to reduce feed intake and digestible energy intake when compared with cereal-based diets (Magowan et al 2004). It is not known whether this effect occurs as a result of the higher levels of fibre in by-product-based diets or as a result of a reduction in palatability arising from the inclusion of oil in the pellet. The aim of this experiment was to investigate the effect of method of vegetable oil blend application (either incorporated directly into the pellet (IN), or sprayed on after pelleting (SP)) on the performance and carcass characteristics of commercially housed finishing pigs.
