Field peas are used increasingly as a source of energy and amino acids in swine rations in Western Canada. The DE content in 11 field pea samples ranged from 3098 to 3739 kcal/kg (1997 PSCI Annual Research Report). The objective of this study was to relate content of field pea samples with chemical and physical characteristics to enable subsequent calculation of prediction equations. Overall, ether extract was the only characteristic with a statistical significant relationship with DE content. We were unable to predict the DE content of the field pea samples accurately with the chemical or physical characteristics included in the study.
