The aim of this study was to evaluate the supplementation of Lactobacillus casei in sows and its effect on the zootechnical parameters of piglets. A total of 18 F1 Landrace x Large White sows were distributed in three completely randomized groups: control and two groups supplemented with L. casei (T1: 10 x 106 CFU [colony forming units]; T2: 10 x108 CFU). The doses were administered weekly orally 2 h after the first feeding of the day (09:00) for 180 days, covering a productive cycle. Results of zootechnical variables of each female and her piglets at the peripartum, at weaning and at the new service of the female were evauated. In the peripartum, a greater mean body weight of total births (PPNT) and average birth body weight were found (PPNV) in the supplemented animals compared to the control group (p<0.05). In the lactation phase there was a greater total weight per litter at weani...

En un sector competitivo como el de manufactura, las organizaciones buscan que sus productos respondan a la demanda y expectativas del mercado y que incluye: entregas a tiempo, calidad y costo. Sin embargo, aun cuando las empresas hacen mejoras en sus procesos, algunos cuellos de botella obstaculizan sus objetivos. Entre estos, el tiempo de cambio de formato, constituyéndose en un reto minimizarlos por la eliminación de actividades que no generan valor. El objetivo de la investigación fue implementar la metodología SMED (Single-Minute Exchange of Die por sus siglas en inglés) en el proceso de extrusión de maca en una empresa alimentaria. Atendiendo a su diseño metodológico, la investigación fue del tipo aplicada con enfoque cuantitativo, diseño preexperimental y longitudinal por su temporalidad. La población fue la producción de maca gelatinizada. Los hallazgos demostraron qu...
