N2 - The apparent total tract digestibility (ATTD) (trial 1) and the apparent (AID) and standardized (SID) ileal digestibility of the amino acids (AAs) (trial 2) in sunflower meal (SM) were evaluated with the addition of exogenous multicarbohydrase (MC) and phytase (Phy). A total of 80 28-day-old broilers were allotted in a completely randomized design to receive treatments up to 35 days of age. A 2 × 2 factorial design was used to determine the enzyme effects, on the ATTD of dry matter, nitrogen, calcium, phosphorus, and fibre, energy use, and the AID and SID of AA, in five replicate cages. Synergic effect was identified between MC and Phy on the ATTD of minerals and fibre. The same benefit occurred with the isolated inclusion of MC on the ATTD of dry matter, nitrogen, and energy of SM. The effects of enzyme inclusion on the AID and SID of AAs in SM, established by comparing the means, suggested a higher effect to the addition of MC + Phy combibation. Supplementation of MC or combination with MC and Phy was a viable alternative to increase the ATTD of nutrients and energy. The addition MC + Phy higher AID and SID of AA from SM.
