Abstract：
Claw diseases have a profound impact on cattle welfare, affecting behaviors such as grazing, rumination, rest, decubitus, and water consumption. This study aimed to assess the prevalence of claw lesions and classify them according to the ICAR Claw Health Atlas (International Committee of Animal Recording) in two slaughterhouses. The influence of claw lesions on carcass weight, classification, and fat deposition was also examined. Involving 343 crossbreed cattle from 103 different extensive or semi-intensive farms, this study found an animal prevalence of claw disorders at 65.8%, with a higher incidence in females (n = 207, 60.35%) compared to males (n = 136, 39.65%). Despite the observed prevalence, claw lesions were not influenced by age or sex (p > 0.05). The main claw lesions identified, including heel horn erosion, double sole, and asymmetric claw, were consistent with the cattle management practices in the study area. These cattle were raised in small, rustic premises with uneven floors, utilizing a mix of manure and plant material as bedding and lacking access to pasture. Also, no negative economic impact was detected concerning carcass weight, classification, or fat deposition. Consequently, it was concluded that the presence of claw lesions in beef cattle raised under the characteristic management of this geographical area does not adversely affect animal health or farm economics.
摘要：
爪病对牛福利有深远的影响,影响放牧等行为，沉思，休息,褥疮,和水的消耗。这项研究旨在评估爪病变的患病率，并根据两个屠宰场的ICAR爪健康地图集（国际动物记录委员会）对其进行分类。爪病变对屠体重量的影响，分类，和脂肪沉积也被检查。涉及来自103个不同的广泛或半密集农场的343头杂交牛，这项研究发现，动物爪障碍的患病率为65.8%，女性（n=207，60.35％）的发病率高于男性（n=136，39.65％）。尽管观察到了患病率，爪病变不受年龄和性别的影响(p>0.05)。确定了主要的爪病变，包括鞋跟角侵蚀，双鞋底,和不对称的爪子，与研究区域的牛管理实践一致。这些牛从小就被饲养，质朴的房屋，地板不平坦，利用粪便和植物材料的混合物作为床上用品，无法进入牧场。此外，未检测到有关car体重量的负面经济影响，分类，或者脂肪沉积.因此,结论是，在该地理区域的特色管理下饲养的肉牛中，爪病的存在不会对动物健康或农场经济产生不利影响。
