Abstract

Published data regarding the energy content of rice for pigs are scarce, apart from the NRC's (1998) estimate of 14.9 MJ of digestible energy (DE)/kg for white rice. Extruded rice most likely has a higher energy value for pigs than white rice because of its high digestible starch content. Establishing the energy content of extruded rice is needed so diets can be formulated accurately for pigs of different weights. The purpose of this study was to examine the DE and calculated net energy (NE) contents of two types of extruded rice in weaner and grower pigs. The hypotheses tested were 1) rice with a lower amylose-to-amylopectin ratio will have a higher DE and NE content than a variety with a higher amylose-to-amylopectin ratio, and 2) heavier pigs will extract more energy from rice than lighter pigs.
