La presente investigación describe las representaciones sociales sobre participación de los actores sociales y sus efectos en la gestión pública municipal del distrito de Nuñoa período 2015 – 2016. Para ello se utilizó el diseño transversal no experimental, con enfoque cuantitativo. La muestra fueron pobladores 80 dirigentes y 23 funcionarios de la municipalidad. El instrumento de medida aplicado fue el cuestionario. Para el procesamiento y análisis estadístico de la información se utilizó el programa SPSS. Resultado: El trabajo permitió concluir que las representaciones sociales sobre participación de los actores sociales son positivos porque los principales elementos relevantes que dan el soporte es la articulación de los actores sociales generando efectos e impactos adecuados para el desarrollo local, teniendo equipos operativos que generan confianza, con mucha experi...

This study aimed to determine the impact of age on the fecal microbiota in the genetic nucleus of cattle, with a focus on microbial richness, composition, functional diversity, and correlations with blood parameters. Fecal and blood samples from 21 cattle were analyzed using 16S rRNA gene sequencing. Older cattle exhibited greater bacterial diversity and abundance, with significant changes in alpha diversity indices (p < 0.05). Beta diversity analysis revealed significant variations in microbial composition between age groups and the interaction of age and sex (p < 0.05). Correlations between alpha diversity, community composition, and hematological values highlighted the influence of microbiota on bovine health. Beneficial butyrate-producing bacteria, such as Ruminococcaceae, were more abundant in older cattle, suggesting a role in gut health. Functional diversity analysis indicated tha...

This study evaluated the gut microbiota and meat quality traits in 11 healthy female cattle from the Huaral region of Peru, including 5 Angus, 3 Braunvieh, and 3 F1 Simmental × Braunvieh. All cattle were 18 months old and maintained on a consistent lifelong diet. Meat quality traits, including loin area, fat thickness, muscle depth, and marbling, were assessed in vivo using ultrasonography. Fecal samples were collected for microbiota analysis, and DNA was extracted for 16S and 18S rRNA sequencing to characterize bacterial, fungal, and protist communities. Significant correlations were observed between microbial genera and meat traits: Christensenellaceae R-7 and Alistipes were positively associated with marbling and muscle area, while Rikenellaceae RC9 showed a negative correlation with fat thickness. Among fungi, Candida positively correlated with marbling, while Trichosporon was negat...
