Evaluation of Protein Digestibility in Canola Meals between Caecectomised and Intact Adult Cockerels
The experiment was conducted to evaluate
digestibility quantities of protein in Canola Meals (CMs) between
caecectomised and intact adult Rhode Island Red (RIR) cockerels
with using conventional addition method (CAM) for 7 d: a 4-d
adaptation and a 3-d experiment period on the basis of a completely
randomized design with 4 replicates. Results indicated that
caecectomy decreased (P<0.05) apparent and true digestibility
quantities of protein for CMs, except for CMs 2 and 3. The mean
apparent and true digestibility quantities for all CMs in
caecectomised (80.5 and 81.4%, respectively) were (3.1 and 3.3%,
respectively) less (P<0.05) than intact cockerels (83.6 and 84.7%,
respectively). Therefore, the caecectomy method increases accuracy
of the digestibility measurements of protein for this meal in bioassays
based on excreta collection in adult cockerels.
