dc.description.abstractTo improve hen welfare, several studies have investigated various environmental enrichments thatsuit different laying hen production systems. The positive results of these studies can enable suchenvironmental enrichments to be utilized in commercial laying hen production. This paper reviewedthe effects of environmental enrichments in different laying hen production systems on hen welfareand egg quality. The successfully proven environmental enrichments in free-range productionsystem include forage, shelterbelt, and artificial shade in outdoor area and novel objects and Hshaped perching structures in indoor. These are associated with increased range use that positivelyaffects hen welfare. In aviary system, perches, and litter materials (e.g., straw, sand) asenvironmental enrichments are linked to improved behavioral expression, reduced stress, andenhanced immune system. Under the litter system, environmental enrichment with substrates (e.g.,pecking stones, alfalfa blocks, silage, straw, barley) has been found to increase the foragingbehavior of laying hens. This reduces severe feather pecking thus, improving the plumage conditionof hens. Although the effects of environmental enrichments on hen welfare have been assessed andscientifically proven in the reviewed studies, significant progress of their impact on egg qualitytraits has not been reported. The studies have shown that environmental enrichments have nosignificant effect on egg quality traits. Also, appropriate pasture or plant species as environmentalenrichments in free-range production system in relation to hen welfare and egg quality have notbeen identified. Therefore, it is important to continue studies on environmental enrichments whileemphasizing their influence on egg quality since it is a major performance trait in the egg industry.In addition, there is a need for studies to identify ideal pasture or plant species for free-rangeproduction system that positively affects hen welfare and egg quality
