摘要

本研究的目的是利用系统评价-荟萃分析（SR-MA）方法，评估用热刀片或红外辐射修剪鸟喙对蛋鸡死亡率、产蛋量、啄羽毛和皮质酮水平的影响。共鉴定了1775条引文。经评估的禽鸟数量为皮质酮76只，死亡率6172只，产蛋率5460只。评估了23篇文章，其中13篇纳入定量综合。与未修剪的鸟类相比，经过热叶片修剪的鸟类的死亡率较低（相对危险度RR = 0.47; p = 0.087），异质性较高（I2 = 94.64%）。浅喙（≤5毫米；RR = 0.64; p < 0.0001）和深喙（>； 5毫米；RR = 0.02; p < 0.0001）的修剪都比未修剪的鸟类降低了死亡率。没有一致的证据表明，修剪喙与产蛋量或皮质酮水平的变化有关；然而，由于研究数量少且方法可变性，这些发现应谨慎解释。红外喙修剪似乎是一个有前途的，侵入性较小的替代方案，显示潜在的福利效益，而不影响性能。需要进一步的规范化研究来加强结论，特别是在应激相关的生理反应方面。

Productive and welfare parameters in trimmed laying hens: A systematic review-meta-analysis

The objective of this study was to evaluate the effects of beak trimming—using a hot blade or infrared radiation—on mortality, egg production, feather pecking, and corticosterone levels in laying hens, using systematic review-meta-analysis (SR-MA) methodology. A total of 1775 citations were identified. The number of birds evaluated was 76 for corticosterone, 6172 for mortality, and 5460 for egg production. Twenty-three articles were assessed, with 13 included in the quantitative synthesis. Birds subjected to hot blade trimming showed a lower probability of mortality (Relative Risk - RR = 0.47; p = 0.087) compared to untrimmed birds, with high heterogeneity (I² = 94.64 %). Both shallow (≤ 5 mm; RR = 0.64; p < 0.0001) and deep (> 5 mm; RR = 0.02; p < 0.0001) beak trimming reduced mortality compared to untrimmed birds. No consistent evidence was found linking beak trimming to changes in egg production or corticosterone levels; however, due to the low number of studies and methodological variability, these findings should be interpreted with caution. Infrared beak trimming appears to be a promising, less invasive alternative, showing potential welfare benefits without compromising performance. Further standardized research is needed to strengthen conclusions, especially on stress-related physiological responses.

期刊介绍： Research in Veterinary Science is an International multi-disciplinary journal publishing original articles, reviews and short communications of a high scientific and ethical standard in all aspects of veterinary and biomedical research. The primary aim of the journal is to inform veterinary and biomedical scientists of significant advances in veterinary and related research through prompt publication and dissemination. Secondly, the journal aims to provide a general multi-disciplinary forum for discussion and debate of news and issues concerning veterinary science. Thirdly, to promote the dissemination of knowledge to a broader range of professions, globally. High quality papers on all species of animals are considered, particularly those considered to be of high scientific importance and originality, and with interdisciplinary interest. The journal encourages papers providing results that have clear implications for understanding disease pathogenesis and for the development of control measures or treatments, as well as those dealing with a comparative biomedical approach, which represents a substantial improvement to animal and human health. Studies without a robust scientific hypothesis or that are preliminary, or of weak originality, as well as negative results, are not appropriate for the journal. Furthermore, observational approaches, case studies or field reports lacking an advancement in general knowledge do not fall within the scope of the journal.
