Abstract: This experiment was conducted to determine the effects of graded levels of Linpro (an extruded product produced using a 50:50 combination of full-fat flax seed and field peas) on broiler performance and nutrient digestibility. A total of 150, two-day old, male broiler chicks (Ross-308 line; Lilydale Hatchery, Wynyard, Saskatchewan) weighing an average of 62.6?0.6 g were randomly assigned to one of five dietary treatments. The control diet was based on wheat and soybean meal while the experimental diets contained 5, 10, 15 or 25% Linpro added at the expense of wheat and soybean meal. Digestibility coefficients for dry matter and gross energy declined in a linear manner (P=0.001) with increasing levels of Linpro in the diet. Digestibility coefficients for crude protein exhibited a cubic (P=0.019) effect due to Linpro incorporation. There were no significant differences in weight gain or feed intake due to the incorporation of Linpro in the diet. Feed conversion declined in a linear manner (P=0.01) as the level of Linpro in the diet increased. The overall results of this experiment indicate that Linpro (extruded full-fat flax seed and peas) can be fed at levels as high as 25% of the diet without significantly affecting growth rate while depressing feed conversion to a lesser extent than has been reported for untreated flax seed and peas. Therefore, use of this product may provide poultry producers with a mechanism to alter the fatty acid composition of poultry meat without dramatic reductions in performance since feeding full-fat flax seed to poultry has been shown to significantly increase the incorporation of omega-3 fatty acids into carcass tissues.
