Resumen
El objetivo del presente estudio, consistió en evaluar la ganancia de peso vivo de terneros lactantes de la raza Brown Swiss, criados bajo dos sistemas: crianza y alimentación. La investigación se desarrolló en el distrito de Molinopampa, Amazonas, Perú, desde el 11 de noviembre del 2017 al tres de marzo del 2018, usando 12 terneros en la etapa de lactación, quienes presentaron similares características fenotípicas y genotípicas. Los terneros permitieron evaluar el efecto de las variables: sistema de crianza y sistema de alimentación, sobre los índices productivos, para lo cual se trabajó con un diseño Completamente al azar (DCA), con estructura factorial de tratamientos (2A x 2B). El factor A, estuvo representado por el sistema de crianza y el factor B por el sistema de alimentación. Como resultado se ha determinado que existen diferencias significativas entre las medias de los tratamientos para las variables: ganancia de peso vivo P 0.041 < α 0.05 y conversión alimenticia P 0.030 < α 0.05, obteniendo diferencias altamente significativas para la variable costo de producción P 0.000 < α 0.01. En cambio, para la variable mérito económico, se determinó que no existe diferencias significativas entre tratamientos P 0.097 > α 0.05.
The objective of this study was to evaluate the live weight gain of suckling calves of the Brown Swiss breed, reared under two rearing and feeding systems. The research was carried out in the district of Molinopampa, Amazonas, Peru, from November 11, 2017 to March three, 2018, using 12 calves in the lactation stage, who presented similar phenotypic and genotypic characteristics. The calves made it possible to evaluate the effect of the variable rearing system and feeding system, on the productive indices, for which a completely randomized design (DCA) was used, with a factorial structure of treatments (2A x 2B). Factor A was represented by the rearing system and factor B by the feeding system. As a result, it has been determined that there are significant differences between the means of the treatments for the variables live weight gain P 0.041 < α 0.05 and feed conversion P 0.030 < α 0.05, highly significant differences for the production cost variable P 0.000 < α 0.01. On the other hand, for the economic merit variable, it was determined that there are no significant differences between treatments P 0.097 > α 0.05.
