摘要
This work reviews the effect of environmental enrichments (perches, platforms, stocking density, outdoor access, bale, and dust bathing substrates) on the performance of fast and slow-growing commercial broiler strains. The performance of both slow and fast-growing commercial broiler strains under conventional production systems are generally poor, especially regarding the welfare status. One of the strategies to improve the performance of commercial broiler strains is by adding enrichment objects to production systems. The addition of enrichments to production systems should improve animal welfare, have no negative effect on production performance, and be both economically practicable and feasible to employ. Perches and platforms are the most common enrichments used to increase the activity of broiler chickens to improve leg conditions. The use of perches and platforms could lead to the reduction in the incidence of footpad dermatitis, hockburns and breast blisters, with subsequent effects on meat quality. Moreover, the provision of outdoor access could improve the biology responses of broiler chickens to various environmental stimuli, with a profound effect on performance and meat quality traits. Furthermore, another enrichment strategies that could increase the exploratory behavior and the general welfare of broiler chickens is the use of dustbathing and bale subtrates. Moreover, adjusting the stocking density provides broiler chickens with the necessary space for movement, reduces crowding, trampling and the associated agonistic behavior. However, the effect of some of these enrichments (perches, platform, bale) objects may vary depending on height, age, sex, and strain of the chickens.
