Abstract

Se determinó la composición química y digestibilidad aparente de nutrientes del fermentado sólido (FES) de tubérculos de taro (Colocasia esculenta (L) Schott) de desecho inoculados con yogur natural en cerdos de crecimiento. Se determinó la materia seca (MS), materia orgánica (MO), proteína bruta (PB), fibra bruta (FB), cenizas, extracto etéreo (EE), extractos libres de nitrógeno (ELN) y energía bruta (EB). Para el estudio de digestibilidad aparente de la MS, MO, PB, FB, ELN y EB se utilizaron 12 cerdos castrados Landrace x Duroc x Pietrain de 25 ± 2 kg distribuidos en tres grupos con cuatro animales cada uno y alimentados con dietas con 0, 10 y 20% de inclusión de FES (T0, T10 y T20, respectivamente). El FES presentó alto contenido de MS (83.33%), MO (93.77%), PB (13.95%), ELN (72.78%) y EB (4162.13 kcal kg MS-1) y bajos niveles de EE (1.50%), FB (5.54%) y cenizas (6.23%). Los mayores coeficientes de digestibilidad de la MS (91.37%), MO (96.36%), PB (87.81%) y FB (54.75%) se obtuvieron en la dieta T20 (p<0.05). No hubo diferencias significativas para la digestibilidad del ELN y EB. En conclusión, los tubérculos de taro procesados por FES e incorporados en la dieta de cerdos en crecimiento al 10 y 20% no afectaron negativamente la digestibilidad aparente de la MS, MO, PB, FB, ELN y EB, lo que garantiza un alimento de adecuadas características nutricionales para los cerdos.

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 highest digestibility coefficients of the DM (91.37%), OM (96.36%), CP (87.81%) and CF (54.75%) were obtained in the T20 diet (p<0.05). There were no significant differences for NFE and GE digestibility. In conclusion, taro tubers processed by SSF and incorporated into the diet of growing pigs at 10 and 20% did not negatively affect the apparent digestibility of DM, OM, CP, CF, NFE and GE, which guarantees a food of adequate nutritional characteristics for pigs.

Selection and characterization of probiotic lactic acid bacteria and its impact on growth, nutrient digestibility, health and antioxidant status in weaned piglets

Runjun Dowarah, Ashok Kumar Verma, Neeta Agarwal … (2018)

The present study was aimed to develop an effective probiotic lactic acid bacteria (LAB) from piglet feces and in vitro characterization of probiotic properties. To confirm host-species specificity of probiotics, the efficacy of isolated LAB on growth, nutrient utilization, health and antioxidant status was observed in early weaned piglets. A total of 30 LAB were isolated from feces of five healthy piglets (28d old). All isolates were Gram positive, cocco-bacilli and catalase negative. Out of thirty LAB isolates, twenty were shortlisted on the basis of their tolerance to pH (3.0, 4.0, 7.0 and 8.0) and bile salts (0.075, 0.15, 0.3 and 1.0%). Whereas, fourteen isolates were selected for further in vitro probiotic characterization due higher (P 45 percent). These isolates fermented twenty-seven different carbohydrates but were negative for ONPG, citrate and malonate. Also enabled to synthesize amylase, protease, lipase and phytase. They were sensitive to penicillin, azithromycin, lincomycin, clindamycin, erythromycin, cephalothin and chloramphenicol and resistant to ciprofloxacin, ofloxacin, gatifloxacin, vancomycin and co-trimoxazole. Except three isolates, all showed antagonistic activity (>60% co-culture activity) against Escherichia coli, Salmonella Enteritidis, Salmonella serotype (ser.) Typhimurium, Staphylococcus intermedius, Staph. chromogenes, Proteus mirabillis, Areomonas veonii, Bordetella bronchioseptica and Klebsialla oxytoca. The isolate Lacp28 exhibited highest tolerance to acidic pH and bile salts (up to 0.3%), phytase activity, cell surface hydrophobicity, antagonistic activity and co-culture assay (>80% growth inhibition). Host specificity of Lacp28 was further confirmed by heavy in vitro adhesion to pig intestinal epithelium cells compared to chicken. Hence, Lacp28 was selected and identified by phylogenetic analysis of 16S rRNA as Pediococcus acidilactici strain FT28 with 100% similarity (GenBank accession nos. KU837245, KU837246 and KU837247). The Pediococcus acidilactici FT28 was selected as potential probiotic candidature for in vivo efficacy in weaned pigs. Thirty-six crossbred piglets (28d) were randomly distributed into three groups (four replicates of three each) namely, basal diet without probiotics (T0) or with Lactobacillus acidophilus NCDC15 (conventional dairy-specific probiotic; T1) or Pediococcus acidilactici FT28 (swine-specific probiotic; T2). At end of the experiment, six piglets of similar body weight were selected to conduct digestion trial for estimation of nutrient digestibility. Results of the study indicated that supplementation of both probiotics improved (P<0.001) FCR compared to control without significant effect in average daily gain and DM intake. However, the apparent digestibility of crude protein and ether extract was better (P<0.01) in pigs fed P. acidilactici FT28 compared control and L. acidophilus fed groups. The total WBC and RBC count, serum glucose, total protein, albumin and globulin concentration was higher (P<0.05) in P. acidilactici FT28 fed group with better (P<0.05) catalase and superoxide dismutase activity measured in erythrocyte. It is concluded that species-specific Pediococcus acidilactici FT28 isolated with potential in vitro probiotic properties and also hold probiotic candidature by showing the potential capabilities with higher nutrient digestibility, heamato-biochemical and antioxidant status compared to control and Lactobacillus acidophilus NCDC15.
