摘要

2022 年全国牛肉质量审核 (NBQA)-2022 是当前美国牛肉行业市场母牛和公牛部门的基准,可与以往的审核进行比较,作为监督行业进展的一种方法。从 2021 年 9 月到 2022 年 5 月,对全美 20 家商业牛肉加工厂的牲畜拖车(n = 125)、活畜(n = 5430)和宰后藏匿牲畜(n = 6674)进行了调查。在所有接受调查的拖车中,55.3% 的拖车将牛从拍卖牛舍运往加工厂。在接受调查的所有卡车司机中,63.6% 表示已获得牛肉质量保证认证。大多数牛(77.0%)在接受流动性评估时都是健康的。肉牛和公牛的平均体况评分(9 分制)分别为 3.8 分和 4.4 分,而奶牛和公牛的平均体况评分(5 分制)分别为 2.3 分和 2.6 分。在接受调查的牛只中,45.1% 的牛只没有明显的活体动物缺陷,37.9% 的牛只只有一个缺陷。在奶牛出现的缺陷中,64.6%是由于乳房问题造成的。47.5%的奶牛乳房饱满。几乎所有牛都没有明显的脓肿和结节(分别为 97.9% 和 98.2%)。在所有接受调查的牛中,89.4% 的牛没有长角。肉牛以黑皮牛为主(分别占母牛和公牛的 68.9% 和 67.4%)。荷斯坦牛是主要的奶牛,占奶牛总数的 85.7%,占公牛总数的 98.0%。只有 3.1% 的动物没有任何形式的标识。NBQA-2022 的研究结果表明该行业有所改善,并确定了需要继续教育和研究的领域,以改善市场奶牛和公牛福利及牛肉质量。

National Beef Quality Audit – 2022: Transportation, mobility, live cattle, and hide assessments to determine producer-related defects that affect animal welfare and the value of market cows and bulls at processing facilities
The National Beef Quality Audit (NBQA)-2022 serves as a benchmark of the current market cow and bull sectors of the U.S. beef industry and allows comparison to previous audits as a method of monitoring industry progress. From September 2021 through May 2022, livestock trailers (n = 125), live animals (n = 5,430), and post-slaughter hide-on animals (n = 6,674) were surveyed at 20 commercial beef processing facilities across the U.S. Cattle were transported in a variety of trailer types for an average distance of 490.6 km and a mean transport time of 6.3 h. During transit, cattle averaged 2.3 m2 of trailer space per animal indicating sufficient space was provided according to industry guidelines. Of all trailers surveyed, 55.3% transported cattle from an auction barn to a processing facility. When surveyed, 63.6% of all truck drivers reported to be Beef Quality Assurance certified. The majority (77.0%) of cattle were sound when evaluated for mobility. Mean body condition scores (9-point scale) for beef cows and bulls were 3.8 and 4.4, respectively, whereas mean body condition scores (5-point scale) for dairy cows and bulls were 2.3 and 2.6, respectively. Of cattle surveyed, 45.1% had no visible live animal defects, and 37.9% had only a single defect. Of defects present in cows, 64.6% were attributed to an udder problem. Full udders were observed in 47.5% of all cows. Nearly all cattle were free of visible abscesses and knots (97.9% and 98.2%, respectively). No horns were observed in 89.4% of all cattle surveyed. Beef cattle were predominantly black-hided (68.9% and 67.4% of cows and bulls, respectively). Holstein was the predominant dairy animal observed and accounted for 85.7% of the cows and 98.0% of the bulls. Only 3.1% of all animals had no form of identification. Findings from the NBQA-2022 show improvements within the industry and identified areas that required continued education and research to improve market cow and bull welfare and beef quality.

期刊介绍: Translational Animal Science (TAS) is the first open access-open review animal science journal, encompassing a broad scope of research topics in animal science. TAS focuses on translating basic science to innovation, and validation of these innovations by various segments of the allied animal industry. Readers of TAS will typically represent education, industry, and government, including research, teaching, administration, extension, management, quality assurance, product development, and technical services. Those interested in TAS typically include animal breeders, economists, embryologists, engineers, food scientists, geneticists, microbiologists, nutritionists, veterinarians, physiologists, processors, public health professionals, and others with an interest in animal production and applied aspects of animal sciences.
