Maternal Behavior, Posture Change, and Production Performance of Lactating Sows Housed in an Enriched Environment
This study aimed to evaluate whether adding straw to a loose-farrowing house promotes maternal functions and production. Forty-eight sows (Landrace× Large White) were housed in either a farrowing pen without straw (C, n = 24) or with straw (S, n = 24). Behaviors were observed using video recordings and were statistically analyzed. Lateral recumbency was […]
Duration of environmental enrichment influences the magnitude and persistence of its behavioral effects on mice
A wide range of data in the literature suggests that environmental enrichment has beneficial effects on various cognitive parameters in rodents. However, the magnitude of these effects and their persistence after the cessation of enrichment vary markedly across studies, with the use of different enrichment protocols probably playing a significant role in this variation. Using […]
Impact of social isolation and enriched environment during adolescence on voluntary ethanol intake and anxiety in C57BL/6J mice
This study was designed to determine the impact of an enriched environment in a previously established stress model of isolation during early development that induces high alcohol (ethanol) self-administration. The study was conducted with male and female C57BL/6J mice housed in isolation or in groups that were either provided or withheld enrichment during adolescence. The […]
Effects of environmental enrichment on decision-making behavior in pigs
The animal’s emotional state, potentially modulated by environmental conditions, may affect cognitive processes such as interpretation, judgement and decision making behaviour. The Iowa Gambling Task (IGT) is a common method to examine decision making behavior in humans in terms of risk avoidance and risk taking that reflects the underlying emotional state of the subject. In […]
