La carne de pollo es la más producida y consumida en Perú en comparación a la carne de res, cerdo y pescado. Actualmente existen dos líneas genéticas predominantes (Cobb y Ross) en el mercado de pollos de carne y se está por re-introducir una tercera línea genética (Hubbard). El objetivo del presente estudio fue evaluar y comparar el comportamiento productivo y económico entre cuatro líneas genéticas bajo las mismas condiciones de manejo y medio ambiente. Para ello se emplearon 300 pollos machos de un día de edad que fueron distribuidos en un diseño completamente al azar (DCA) en cuatro tratamientos (Ross 308, Hubbard M99, Hubbard M77 y Cobb 500) con tres repeticiones por tratamiento. El periodo de crianza fue de 42 días al final de los cuales se evaluó la mortalidad (M%), ganancia de peso (Gdp), consumo de alimento (CTA), índice de conversión alimenticia (ICA), índice ...

Urban transport services in Bolivia are characterized by their informality, self-management, atomization, reduced quality, as well as a high capacity for route multiplication, the main link with urban sprawl. However, an analysis of the level of accessibility that this mode of service allows in Cochabamba shows that it is a highly efficient service under this indicator. The level of accessibility that paratransit allows contributes to the reduction of inequalities and articulation of the peripheries to the opportunities offered by the city.
