Two experiments were carried out to evaluate in pigs the use of full-fat canola. In the first one apparent and standardized ileal digestibility (AID and SID) of dry matter (DM), crude protein (CP), amino acids (AA) and energy (E) were evaluated in twelve pigs. In the second one apparent fecal digestibility (AFD) of CP and E were evaluated in eight pigs. In both experiments, full-fat canola (FFC) was used to prepare two diets, a full-fat canola milled and corn starch diet (FFCM-CS), and another with full-fat canola and sorghum milled together (FFCSM). The results show that AID of DM (71.4), CP (54.9) and E (67.6) was similar (P >0.10) between the two diets. SID and AID differ in alanine and leucine (P <0.001), phenylalanine, glutamic acid, histidine and valine (P <0.01); and The SID of serine (P <0.05). In all cases, the higher digestibility was observed in the FFCSM diet. The AFD of DM and CP (P <0.001), and E were lower (P <0.01) in FFCSM diet than in FFCM-CS diet. It is concluded that AID and SID of protein and amino acids, as well as AFD of energy, are low in full-fat canola, reducing the possibility of its inclusion in diets for pigs. However, the mix of full-fat canola and sorghum milled together improved apparent ileal digestibility of amino acids allowing its use as an ingredient in the formulation of rations.

The objective of the study was to evaluate the addition of phytase (P) and pectinase, glucanase and hemicellulose (PGH) activities on sorghum-soybean- canola based diets, and a xylanase (X) on diets with dry distillers grain with solubles (DDGS) on the ileal and fecal digestibility of nutrients (Exp 1) and the growth performance (Exp 2) of growing-finishing pigs. In Exp 1, two Basal diets were formulated (B1: sorghum-soybean-canola and B2: sorghum-soybean-canola + DDGS) and the treatments were: 1) B1+P, 2) B1+P+PGH, 3) B2+P, 4) B2+P+PGH, 5) B2+P+X, and 6) B2+P+PGH+X. Exp 2 included four treatments: 1) Positive control (sorghum-soybean-canola) with normal energy; 2) Same as 1, but low in energy; 3) Same as 2 +F+PGH, 4) Same as 3 +GSDS +X. In Exp. 1, the ileal energy digestibility was improved (P<0.05) with +P+PGH, +P+X and +P+PGH+X and the fecal energy digestibility was improved (P<0.05) with +P+X. The PGH released 122 kcal at the ileal level and the X released 147 and 132 kcal of DE/kg of feed at the ileal and fecal level. In Exp 2, the feed efficiency between the Positive control and the Low-energy +P+PGH Treatment was similar (P<0.01), but the Low-energy +P+PGH Treatment had higher (P<0.01) energetic efficiency. The energetic value of DDGS was improved with the addition of P, PGH and X, but the growth response observed in this trial was not consistent.
