Evaluation of high-protein canola meals fed to growing chicks and weanling pigs
type: CreativeWork
description: Three experiments were conducted to determine and compare the nutritional value among 2 high-protein canola meals (CMA and CMB), conventional canola meal (CM-CV), and soybean meal (SBM). The objective of Experiment 1 was to determine P bioavailability in the canola meals and SBM relative to KH2PO4 when fed to growing chicks and to determine if P bioavailability was increased by addition of microbial phytase to a P-deficient CMA diet. Results indicated that as P level was increased by addition of KH2PO4, CMA, CMB, or SBM, weight gain and tibia ash (mg/tibia and %) were increased linearly (P < 0.05). Based on tibia ash %, bioavailabilities of P in CMA, CMB, conventional CM, and SBM relative to KH2PO4 were 15, 20, 13, and 42%, respectively. A linear increase (P < 0.05) in weight gain and tibia ash was observed with addition of KH2PO4 or phytase to the P-deficient CMA diet. The addition of 250 or 500 units/kg microbial phytase to P-deficient CMA diets resulted in approximately 0.13 and 0.18% P being released, respectively, as estimated using the standard curve method. In Experiment 2, the objective was to determine the digestibility of Ca and P in CMA and CMB fed to growing pigs without or with the addition of microbial phytase, and to compare values obtained in high-protein canola meal with digestibility of Ca and P in CM-CV and SBM. Results indicated that apparent total tract digestibility (ATTD) of Ca and P and standardized total tract digestibility (STTD) of P were not different among treatments. Apparent total tract digestibility of Ca was 62, 66, 69, and 73% for CMA, CMB, CM-CV, and SBM, respectively. Standardized total tract digestibility of P was 55, 60, 49, and 66% for CMA, CMB, CM-CV, and SBM, respectively. Inclusion of phytase to the diets reduced both Ca and P outputs (P < 0.05). Inclusion of phytase also improved (P < 0.05) ATTD of Ca and P and STTD of P, regardless of the ingredient in the diet, and there was no interaction between diet and phytase supplem…
