Lewis et al (1998) observed differences in overall and ileal apparent digestibility of wheat varieties using a wheat / casein diet but no significant relationships with in vitro viscosity of wheat. In the present study six of the varieties used previously were selected to examine if the variety differences would be repeatable using a more commercial diet and the extent of correlation between overall digestibility (OD) and performance parameters. The wheats chosen were Abbott, Caxton, Crofter, Encore, Hussar, Riband (in vitro viscosity range 6.8 - 19.2 cps). Three contained the 1B1R gene (Crofter, Encore, Hussar) and three were soft wheats (Crofter, Encore, Riband). All wheats were harvested in Northern Ireland in 1997.
