Table 3 The economic benefit (profit margin) calculated based on feed consumption, liveweight gain and carcass weight (estimated and real) of maternal composite (Composite) lambs and Merino yearlings (hogget) fed camelina hay (CAMH), camelina meal (CAMM) supplemented pellet diet or control pellet diet (CONT) for all animals up to slaughter¹

¹Values were the average of all 80 Composite lambs and 80 Merino yearlings used in this study, calculated on pen (n = 20) basis with each pen had 8 Composites (n = 8) and 8 Merinos (n = 8), respectively. Values within a row followed by different letters are significantly different at P = 0.05.
SED Standard error of difference. D × B Interaction of diet by breed, NA Not applicable
²Method 1: Profit calculated using 5-year Victorian state average price per kg carcass (AUD $/ kg carcass) for each carcass classifications and carcass weight ranges
³Method 2: Profit margin calculated using 3-year average price per kg carcass received pre-summer and post-summer (AUD $/ kg carcass) for each carcass classifications and carcass weight ranges
