“…Telkänranta and colleagues [ 10 ] found that providing chewable enrichment (sisal rope and newspaper) reduced the occurrence of pen mate manipulation pre-weaning and the severity of tail damage post-weaning, relative to pigs who only had in addition to harder materials (wood shavings and a plastic ball attached to a chain). Brajon et al [ 11 ] found that straw bedding increased animal comfort pre-weaning and reduced biting in the first six days post-weaning. However, they also theorised that the removal of enrichment post-weaning could lead to distress, as pigs who moved from a pre-weaning loose pen enriched with straw performed more belly-nosing than piglets who had been managed in a standard farrowing crate during lactation [ 11 ].…”

This study investigated the behavioural effects of providing different enrichment materials to suckling piglets from 7 days-old until weaning. One object was attached to the pen wall (WALL), and the other was suspended in the middle of the pen (MID). Control group had the hessian fabric in both locations, and the two diverse groups had hessian and bamboo stick in alternate locations (i.e., BMID-HWALL and HMID-BWALL). Piglets behaviour was recorded on D0 (object introduction), D1, D5, D8, D12, and D14; at weaning and 1, 3, 5 and 15 days after. Groups did not differ in approaching or interacting with objects on D0. MID objects attracted more attention than WALL objects (p < 0.01). Piglets interacted more with hessian than bamboo (p < 0.001). They performed more oral manipulation and shaking with hessian (p < 0.001), but more pushing of bamboo (p < 0.001). Interactions with objects increased with time (p < 0.001), especially with hessian (p < 0.01), while interest in bamboo remained unchanged. Control piglets performed more biting than piglets with diverse enrichment (pooled data), both pre- and post-weaning (p < 0.05). Therefore, providing different types of enrichment material can reduce biting behaviour pre- and post-weaning. Hessian was favoured, possibly because this was easier to bite and shake, which were the behaviours most often observed.

“…In the particular case of pigs, the high demand for the consumption of their meat generated an increase in their production and in the way they are housed during their production chain (USDA-FAS, 2019). In farms with semi-intensive and intensive management systems, pigs are constantly exposed to aversive events such as aggressive handling by farm workers (Tallet et al, 2018), early weaning (Siegford et al, 2008), formation of new groups or mix of animals of different ages (Colson et al, 2012), (Verdon et al, 2016), exposure to extreme temperatures (Parker et al, 2010), and housing with little or no social and sensorial stimulation (Merlot et al, 2012;Brajon et al, 2017). Studies indicate that this type of conditions generates stress in animals and, as a consequence, a poor welfare.…”

“…Existen diversos tipos de EE, por ejemplo el social, que incluye interacciones animal-animal y humano-animal, el ocupacional, el físico, que involucra la calidad y cantidad de espacio disponible, y el sensorial que implica la estimulación de los sentidos (Young, 2013). Estudios en el cerdo indican que el EE incrementa la aparición de comportamientos propios de su especie como el exploratorio (Yang et al, 2018) y de juego (Martin et al, 2015), mientras que disminuye estados negativos como la agresividad (Marcet-Rius et al, 2019) y el estrés prenatal (Brajon et al, 2017), además de favorecer habilidades de aprendizaje (Jansen et al, 2009;Douglas et al, 2012).…”

Studies in pigs indicate that EE increases the incidence of behaviors typical from the species, such as exploratory behavior (Yang et al, 2018) and playing behavior (Martin et al, 2015), while it decreases negative states such as aggressiveness (Marcet-Rius et al, 2019) and pre-natal stress (Brajon et al, 2017), in addition to fostering learning abilities (Jansen et al, 2009;Douglas et al, 2012).…”

Introducción La Organización Mundial de Sanidad Animal (OIE), que cuenta con más de 150 países miembros, considera que un animal está en bienestar cuando éste está sano, cómodo, bien alimentado, seguro, es capaz de expresar su comportamiento y no sufre estados desagradables como el dolor, miedo y angustia (OIE, 2008). Desafortunadamente, la producción intensiva de animales para beneficio de los humanos ha mermado la capacidad de las unidades de producción para proveer bienestar animal (AW). En el caso particular del cerdo, la alta demanda en el consumo de su carne ha generado un incremento en su producción y en la forma en la que estos son alojados durante su cadena productiva (USDA-FAS, 2019). En granjas con sistemas de manejo semi-intensivo e intensivo, los cerdos son constantemente expuestos a eventos aversivos como el manejo agresivo por parte de los trabajadores (Tallet et al., 2018), destete precoz (Siegford et al., 2008), la formación de nuevos grupos o mezcla de animales de diferentes edades (Colson et al., 2012), (Verdon et al., 2016), exposición a temperaturas extremas (Parker et al., 2010), y alojamientos con poca o nula estimulación social y sensorial (Merlot et al., 2012; Brajon et al., 2017). Estudios indican que este tipo de condiciones genera estrés en los animales y como consecuencia un pobre bienestar. Uno de los graves problemas del estrés, entendido como una respuesta ante una amenaza real o percibida que altera la homeostasis de un organismo, (McEwen, 2000), es que si ocurre de manera prolongada o continua pueden tener graves efectos negativos. Algunos de los efectos attempts to enter into open arms and risk assessment. In the second experiment, 60 piglets were divided into 4 groups: 1) received enrichment during pregnancylactation, 2) enrichment during weaning, 3) enrichment during pregnancy-lactation-weaning and 4) without enrichment. On post-natal day 70, pigs were exposed to an elevated plus maze. Results showed that pigs from group 1 showed less anxiety during the test compared with groups 3 and 4. This suggested that environmental enrichment during pregnancy-lactation positively impacted the ability of piglets to regulate anxiety.

Environmental enrichment (EE) has shown remarkable effects in improving cognition and addictive behaviour. We tested whether EE could help recover from prenatal stress exposure. Mature Swiss Webster male and virgin female mice were placed together until vaginal plugs were detectable. Next, pregnant rodents were randomized into the control, physically and psychologically stressed groups. The application of stress was initiated on the 10th day of pregnancy and persisted for a week to induce stress in the mice. Open field and elevated plus‐maze (EPM) tests were utilized as explorative and anxiety assays, respectively. A passive avoidance shuttle‐box test was carried out to check anxiety‐modulated behaviour. Morris water maze (MWM) test was undertaken to evaluate spatial learning and memory. Conditioned place preference (CPP) test was selected for evaluation of tendency to morphine consumption. Our results showed that prenatal stress elevated anxiety‐like behaviour in the offspring which EE could significantly alleviate after weaning. We also found a higher preference for morphine use in the physical stress and psychological stress offspring group. However, no difference was observed among the genders. Application of EE for the stress group improved several parameters of the cognitive behaviour significantly. Although prenatal stress can lead to detrimental behavioural and cognitive outcomes, it can in part be relieved by early exposure to EE. However, some outcomes linked to prenatal stress exposure may not be diminished by EE therapy. In light of such irreversible effects, large‐scale preventive actions promoting avoidance from stress during pregnancy should be advised.
