3.2. Apparent nutrient digestibility
Pigs on the probiotic treatments showed 1.8% greater fat (P = 0.026) and 4.4% higher P digestibility (P = 0.016) comparedwith the non-supplemented treatments (Table 6). Pigs fed the lower energy diets exhibited higher ATTD of DM, CF and P,but lower ATTD of fat than pigs fed the standard energy diets. There was an interaction (P < 0.001) between the effects of theprobiotic and diet energy level for the ATTD of CP and Ca (Table 6). Probiotic increased digestibility of CP under lower butnot under the standard level of energy. The probiotic was effective in improving the ATTD of Ca in the standard energy diet,but on lower energy diet, the presence of probiotic resulted in a reduction of ATTD of Ca.
