The physiological and behavioral changes in ungulates are an adaptive response to environmental changes. The endogenous biological clock allows each individual animal to produce these changes in response to environmental fluctuations. The daylight is the main factor that modulates this process, and its changes are reflected by variations in the melatonin concentrations. This review describes the translation of the light signal into changes in hormone concentration in ungulates. Then mechanism as photoperiod modifies physiological processes such as reproduction, and physical and behavioral aspects are presented. Finally this review discusses the relationship of genes in the development of biological clock. The understanding of the mechanisms that modulate the physiological and behavioral changes in ungulates facilitates handling of animals, especially those species where management is the...

Introducción: El tiempo de estancia hospitalaria del binomio madre-hijo luego del parto ha presentado cambios significativos; antes el binomio permanecía de 4 a 5 días luego del parto y en la actualidad ese tiempo fluctúa entre 24 a 48 horas. Existe la preocupación sobre si es un factor asociado al reingreso hospitalario del binomio madre-Hijo debido a complicaciones no detectables en la corta estancia. Objetivo: Determinar la frecuencia de alta temprana y su relación con la seguridad del binomio madre-hijo en una clínica de alta complejidad de Cali, Colombia de abril a junio de 2018 Materiales y métodos: Se realizó un estudio observacional descriptivo longitudinal de binomios madres-hijos(as) atendidos en una IPS de Cali, abril a junio de 2018. Resultados: Se evaluaron 737 registros de la historia clínica correspondientes a binomios madre-hijo que recibieron su atención de pa...
