The chemical composition and apparent digestibility of nutrients of the solid-state fermentation (SSF) of waste taro tubers (Colocasia esculenta (L) Schott) inoculated with natural yogurt fed to growing pigs was determined. Dry matter (DM), organic matter (OM), crude protein (CP), crude fibre (CF), ash, ether extract (EE), nitrogen-free extracts (NFE) and gross energy (GE) were determined. For the study of apparent digestibility of the MS, MO, CP, CF, NFE and GE, 12 castrated Landrace x Duroc x Pietrain male pigs of 25 ± 2 kg were used, distributed in three groups with four animals each and fed with diets containing 0, 10, and 20% of SSF (T0, T10 and T20, respectively). The SSF presented high content of DM (83.33%), OM (93.77%), CP (13.95%), NFE (72.78%) and GE (4162.13 kcal kg MS-1) and low levels of EE (1.50%), CF (5.54%) and ashes (6.23%).

            The content of phenolic compounds and antioxidant activity in powder and cooked extract of wild anise foliage (Piper auritum Kunth) and its effect as a phytobiotic additive for pigs in the post weaning phase were evaluated. Fresh wild anise plants were collected and processed in the laboratory to obtain the powder and foliage extract. The total phenolic content (Folin-Ciocalteu method) and antioxidant activity (ABTS method) were determined. Thirty castrated piglets Landrace x Duroc of 6 ± 0.2 kg were distributed in three experimental groups: T0 (Basal diet without antibiotic growth promoter) BDWAGP; T1 (BDWAGP + inclusion of 1 g of powder/100 g of feed) and T2 (BDWAGP + inclusion of 10 ml of extract/100 g of feed).

The aim of this study was to determine the apparent faecal digestibility of a diet including sacha inchi (Plukenetia volubilis L) seed meal in growing creole pigs. Two male castrated pigs were used, body weight of 50 ± 2 kg, housed in metabolic cages, and under a 2x2 Latin square design. The pigs were fed diets with 0 (control) and 15% inclusion of sacha inchi seed meal, respectively. In the experimental diets and in the faeces it was determined: dry matter (DM), crude protein (CP), crude fibre (CF), fat, nitrogen-free extracts (NFE), gross energy (EB), calcium (CA) and phosphorus (P). The highest apparent digestibility coefficients of DM (82.38%) and P (32.32%) were obtained in the control diet (p<0.05). There were no significant differences for the digestibility of CP, CF, fat, NFE and Ca. In conclusion, the inclusion of 15% sacha inchi seed meal in the diet of growing creole pigs ...
