Recent research results indicate that locally grown feed ingredients express a high variability in nutritional value for growing – finishing pigs. The highest and lowest DE value differed 20% within twenty samples of barley collected from Alberta, Saskatchewan and Manitoba. Field peas are becoming an increasingly important protein and energy source for growing – finishing pigs in Western Canada. The range in nutritional value of field peas has been poorly assessed. Therefore, the objective of the present study was to characterize the DE content in samples of 11 field pea varieties. The DE ranged from 3098 to 3739 kcal/ kg; thus, the difference in DE between the highest and lowest value was 20%. Despite being grown under similar conditions, energy value for sample differed greatly among samples and variation in DE was greater than expected. Because nutritionists try to formulate diets within an accuracy of 1.5%, the issue of ingredient variability requires further study.
