MARISCAL-LANDIN, Gerardo  y  RAMIREZ RODRIGUEZ, Erika. Determination of the digestibility of the protein, amino acids and energy of full fat canola in growing pigs. Rev. mex. de cienc. pecuarias [online]. 2017, vol.8, n.3, pp.297-304. ISSN 2448-6698.  https://doi.org/10.22319/rmcp.v8i3.4505.

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.
