Objetivo: evaluar el efecto de la adición de dos niveles de hojas de ruda (Ruta chalepensis L.) con diferentes niveles de materia seca incubada sobre la mitigación de metano (CH4) y la digestibilidad de la materia seca in vitro. Diseño/metodología/aproximación: Los tratamientos evaluados consistieron en muestras de pasto nativo dominado por pasto kikuyo (Penisetum clandestinum) más la adición de 3 y 6% de hoja de ruda respecto a un control. El CH4 se cuantificó a las 12, 24 y 48 h, post-incubación. Resultados: se registraron diferencias significativas (P<0.01) entre tratamientos en todas las horas de medición; siendo los tratamientos PN0.57 R0%, PN1.19 R3%, PN1.95 R3% y PN2.18 R3% los que presentaron menor producción acumulada de CH4 a las 12, 24 y 48 h, respectivamente. Limitaciones del estudio/implicaciones: los resultados de este trabajo fueron obtenidos a partir de un estudio in vitro; por lo tanto, no son aplicables directamente a las emisiones entéricas in vivo, no obstante, se tiene una aproximación de cuanta energía metabolizable se puede perder en forma de metano. Hallazgos/conclusiones: las hojas de ruda presentaron mayor efecto de mitigación de CH4. En este tenor, los tratamientos PN1.95 R3% y PN2.18 R3% redujeron en 75% y 95% la tasa de producción de CH4 a las 24 y 48 h, con respecto a los tratamientos sin hoja de ruda, y se observó un aumento en la digestibilidad in vitro de la materia seca cuando se compararon los tratamientos con ruda y los tratamientos sin hoja de ésta.

Efficient lipid digestion in formula-fed infants is required to ensure the availability of fatty acids for normal organ development. Previous studies suggest that the efficiency of lipid digestion may depend on whether lipids are emulsified with soy lecithin or fractions derived from bovine milk. This study, therefore, aimed to determine whether emulsification with bovine milk-derived emulsifiers or soy lecithin (SL) influenced lipid digestion in vitro and in vivo. Lipid digestibility was determined in vitro in oil-in-water emulsions using four different milk-derived emulsifiers or SL, and the ultrastructural appearance of the emulsions was assessed using electron microscopy. Subsequently, selected emulsions were added to a base diet and fed to preterm neonatal piglets. Initially, preterm pigs equipped with an ileostomy were fed experimental formulas for seven days and stoma output was collected quantitatively. Next, lipid absorption kinetics was studied in preterm pigs given pure emulsions. Finally, complete formulas with different emulsions were fed for four days, and the post-bolus plasma triglyceride level was determined. Milk-derived emulsifiers (containing protein and phospholipids from milk fat globule membranes and extracellular vesicles) showed increased effects on fat digestion compared to SL in an in vitro digestion model. Further, milk-derived emulsifiers significantly increased the digestion of triglyceride in the preterm piglet model compared with SL. Ultra-structural images indicated a more regular and smooth surface of fat droplets emulsified with milk-derived emulsifiers relative to SL. We conclude that, relative to SL, milk-derived emulsifiers lead to a different surface ultrastructure on the lipid droplets, and increase lipid digestion.

AbstractIn this work, two Peruvian beverages “Masato de Yuca,” typical of the Amazonian communities made from cassava (Manihot esculenta), and “Chicha de Siete Semillas,” made from different cereal, pseudo-cereal, and legume flours, were explored for the isolation of lactic acid bacteria after obtaining the permission of local authorities following Nagoya protocol. From an initial number of 33 isolates, 16 strains with different RAPD- and REP-PCR genetic profiles were obtained. In Chicha, all strains were Lactiplantibacillus plantarum (formerly Lactobacillus plantarum), whereas in Masato, in addition to this species, Limosilactobacillus fermentum (formerly Lactobacillus fermentum), Pediococcus acidilactici, and Weissella confusa were also identified. Correlation analysis carried out with their carbohydrate fermentation patterns and enzymatic profiles allowed a clustering of the lactobacilli separated from the other genera. Finally, the 16 strains were submitted to a static in vitro digestion (INFOGEST model) that simulated the gastrointestinal transit. Besides, their ability to adhere to the human epithelial intestinal cell line HT29 was also determined. Following both procedures, the best probiotic candidate was Lac. plantarum Ch13, a robust strain able to better face the challenging conditions of the gastrointestinal tract and showing higher adhesion ability to the intestinal epithelium in comparison with the commercial probiotic strain 299v. In order to characterize its benefit for human health, this Ch13 strain will be deeply studied in further works.
