Summary
Feed processing and nutritional quality for CPS and Durum wheats have traditionally been expected to be lower than for Hard Red Spring (HRS). Performance of weaned pigs was compared among six wheat classes, whilst considering particle size and diet pellet quality. Results indicated that feed processing quality and growth performance did not differ among wheat classes. Weaned pigs fed various classes of wheat including CPS and Durum may grow similarly.

Introduction
The processing and nutritional quality of wheat is expected to vary among classes; CPS and Durum wheat are currently segregated. A range in wheat protein and fibre or non-starch polysaccharide (NSP) content may partly cause quality variation. The present study was designed to test whether wheat class by itself impacts feed processing or nutritional quality.
