Peacan meal is a mixture of ground peas and canola meal in a ratio of 2:1 by weight. These two locally grown high protein feedstuffs are complimentary for digestible energy and amino acids with respect to swine diets. However, due to the lack of data from experiments using typical Alberta diets, feeding recommendations vary widely. This study was needed to validate the results obtained in previous studies. The experiment determined animal performance when soybean meal was replaced with peacan meal in diets of pigs from 25-50 kg, 50-80 kg and 80-108kg. Different dietary specifications were used in each phase to closely match requirements of the pigs. In each phase there were four treatment diets with peacan meal replacing soybean meal at 0, 33, 67 and 100 percent of supplemental protein in the diets. Within each phase diets were equalized for digestible energy (DE) and lysine. The calculated DE (Mcal/kg) and percent total lysine for diets in phases 1, 2 and 3 were 3.40 and 0.95, 3.25 and 0.82, and 3.10 and 0.7 respectively.

The overall performance results are shown in the table below. There were no significant differences (P<0.05) in average daily gain (ADG), average daily feed intake (ADFI) and feed efficiency (F/G) among treatments groups during each period and for the overall period. Barrows maintained a higher ADFI and ADG than gilts. These results are in agreement with results of the previous study.

Performance of market hogs (25-108kg) with varying levels of peacan meal in the diet.

Animal Performance	% of supplemental protein supplied by peacan meal
	0%	33%	67%	100%
ADG kg/day	0.897	0.856	0.909	0.899
ADFI kg/day	2.77	2.58	2.8	2.77
Feed/gain	3.13	3.08	3.08	3.09

Implication: Peacan meal is a viable protein supplement in diets of market hogs at any level of substitution. Economics depends on its cost compared to other protein supplements.
