摘要
本研究调查了在散养和传统深窝饲养系统中饲养的慢速生长肉鸡与市场上销售的快速生长品种肉鸡的福利情况。研究分为四个主要组(2 种基因型 x 2 种饲养系统),每个主要组有 5 个重复。调查了200只雄性雏鸡(100只慢速生长,100只快速生长)死前和死后基于健康的福利指标和恐惧反应及其严重程度的分布情况。结果发现,两种肉鸡基因型之间的所有福利参数都存在显著差异。在两种饲养系统之间,所有肉鸡福利参数均未发现明显差异。在胸脏和羽毛覆盖率方面,基因型与饲养系统之间存在明显的交互作用(P )。总之,可以说生长缓慢的肉鸡表现出更多基于健康的积极福利指标,它们可能更适合散养肉鸡的肉类生产。规划进一步的研究,尤其是在考虑经济效益、动物福利和生长性能的商业条件下的研究,将是非常有益的。
Health-Based Welfare Indicators and Fear Reaction of Slower Growing Broiler Compared to Faster Growing Broiler Housed in Free Range and Conventional Deep Litter Housing Systems.
This study investigated the welfare of a slow-growing broiler with a commercially available fast-growing breed housed in a free-range and conventional deep litter housing system. There were four main groups (2 genotypes x 2 housing systems), and each main group consisted of 5 replicates. Ante-mortem and postmortem health-based welfare indicators wıth fear reactıons and distribution of severity of them in 200 male chicks (100 slow growing, 100 fast growing) were investigated. All welfare parameters investigated were found to be significantly different between both broiler genotypes. No significant differences were detected for all broiler welfare parameters between the two housing systems. There were significant genotype x housing system interactions for breast dirtiness and feather cover of the birds (P < 0.001). In conclusion, it can be said that slow-growing broilers express more health-based indicators of positive welfare, and they might be more suitable for free-range broiler meat production. Planning further studies especially in commercial conditions that take into account economic efficiency as well as animal welfare and growth performance would be very beneficial.
期刊介绍:
Journal of Applied Animal Welfare Science (JAAWS) publishes articles on methods of experimentation, husbandry, and care that demonstrably enhance the welfare of nonhuman animals in various settings. For administrative purposes, manuscripts are categorized into the following four content areas: welfare issues arising in laboratory, farm, companion animal, and wildlife/zoo settings. Manuscripts of up to 7,000 words are accepted that present new empirical data or a reevaluation of available data, conceptual or theoretical analysis, or demonstrations relating to some issue of animal welfare science. JAAWS also publishes brief research reports of up to 3,500 words that consist of (1) pilot studies, (2) descriptions of innovative practices, (3) studies of interest to a particular region, or (4) studies done by scholars who are new to the field or new to academic publishing. In addition, JAAWS publishes book reviews and literature reviews by invitation only.
