ZANOTTO, D.L. et al. Utilization of canola meal in diets of growing and finishing pigs. Arch. zootec. [online]. 2009, vol.58, n.224, pp.717-728. ISSN 1885-4494.

Ninety pigs (from 25.8 kg until slaugther at 102.6 kg) were used to evaluate the influence of canola meal in swine diets. A randomized block design was arranged in a factorial model with five canola meal levels, two sexes and three replications. Canola meal was included at 20, 40, 60 and 80% substituition of soybean meal considering the reference diet (corn and soybean meal) and keeping simultaneously experimental diets similar in protein and metabolizable energy. Growing, finishing and total period performance and carcass traits were evaluated. Interaction between treatment and gender were observed for fed to gain ratio in all of the periods evaluated. At finishing and total period a quadratic effect of treatment were observed for feed consumption. For weight gain were characterized a quadratic effect for treatment only in the total period. Barrows presented higher feed consumption and weight gain in all evaluated periods. Only treatment and gender had effect on carcass characteristics without interaction effects. Substituition level of 40% soybean meal in reference diet were recomended. This level yields a high weight gain and at consequence heavier carcasses resulting in higher estimated meat production but greater backfat depth and lower meat yield.
