FARFAN-LOPEZ, Charly et al. Digestibility of a Sorghum Blend with an Enzyme Complex in Diets for Pigs. Agrociencia Uruguay [online]. 2016, vol.20, n.1, pp.72-78. ISSN 1510-0839.

An experiment in two periods of eight days each was conducted to determine the apparent total tract digestibility of dry matter (DDM), energy (ADE), and nitrogen (DAN) from a sorghum blend (SB) with an enzyme complex (EC) in diets for growing pigs.Twenty four pigs (35 kg live weight) distributed in a randomized block design (period as block) with four diets and six pigs per diet were used in a 2 × 2 factorial arrangement of treatments. The factors were two ingredients (SB and corn) with or without EC resulting in the following diets: basal with corn (BDC); BDC with the addition of EC (BDC+EC); SB-based diet (SBD) and SBD+CE. The pigs were individually allocated in metabolic cages for total collection of feces. Data were analyzed using PROC MIXED of SAS statistical software, using ANOVA tests, and the GLM-Tukey procedure. There was no effect of EC on the evaluated variables. The ADE varied significantly (P = 0.003) between the two ingredients with values of 3641.49 ± 42.95 kcal /kg DM and 3540.61 ± 55.82 kcal/kg DM for BDC and SBD, respectively. The DAN was greater (P = 0.002) in the BDC (81.75 ± 1.55%) than SBD (77.06 ± 3.44%). It is concluded that the addition of the EC had no effect on the DDM, DAN and ADE in the blend of sorghum grains evaluated in diets for growing pigs
