Abstract

Dietary fibre, when included at levels of up to 100 g/kg in finisher pig diets, can reduce carcase fat without impacting on growth performance (Håkansson et al., 2000). In pigs, the relative proportion of fat deposited during growth increases with age and weight therefore increasing fibre levels during finishing is expected to have the greatest impact on carcase quality. Fibrous ingredients, such as cereal straw, have the potential to be used as a management tool, however, it is important to determine whether the effect of fibre is related to the ingredient itself or to the dilution of dietary energy and nutrients that occurs. It was hypothesised that finisher pigs fed high energy diets containing straw would have similar growth performance but leaner carcases than pigs fed a standard high energy finisher diet. In addition, pigs fed a lower energy diet (+/- straw) were expected to be leaner but slower growing, and therefore less efficient, than pigs fed a standard high energy finisher diet.
