Abstract：
The association between hoof lesions and lying behaviour was assessed on a Holstein-Friesian dairy farm in England. Twenty-nine cows were included in the study. Cows with claw horn disruption lesions (CHDL, n = 8), soft tissue lesions (STL, n = 6), and no lesions (NL, n = 15) were assessed. Data were collected on parity, days in milk (DIM), and mobility scores. Cows were trimmed and treated, and lesions were recorded by a professional foot trimmer. Lying behaviour was assessed before and after claw trimming. The milking herd (n = 96) prevalence of lameness was 32.3%. Mobility was scored using the Agriculture and Horticulture Development Board (AHDB) Mobility Scoring system. Mobility scores were significantly different across lesions groups (p = 0.022). CHDL cows had a mean mobility score of 2.0 ± 0.9 (mean ± SD), STL were scored 1.2 ± 1.3, and NL cows were 0.9 ± 0.7. CHDL were associated with longer lying times (15.00 ± 1.04 h/d; p = 0.0006) and shorter standing times (9.68 ± 2.38 h/d; p = 0.0351) compared with NL lying times (11.77 ± 1.67 h/d) and standing times (12.21 ± 1.67 h/d). STL cows spent significantly less time lying (11.30 ± 2.44; p = 0.0013) than CHDL but not NL cows. No significant differences were found with any of the other lying behaviours. After trimming, CHDL cows spent significantly less time lying down than before trimming (13.66 ± 0.98; p = 0.0125). Cows with NL spent significantly more time lying down (12.57 ± 1.90; p = 0.0398) and had a shorter minimum lying bout duration (0.17 ± 0.09; p = 0.0236) after trimming. In conclusion, lying behaviour in dairy cattle was impacted by type of hoof lesions and hoof trimming.
摘要：
在英格兰的Holstein-Friesian奶牛场上评估了蹄病变与说谎行为之间的关联。29头牛被纳入研究。具有爪角破裂病变的奶牛（CHDL，n=8),软组织病变（STL，n=6),并且没有病变（NL，n=15）进行评估。数据是在奇偶校验上收集的，牛奶中的天数（DIM），和流动性得分。奶牛被修剪和治疗，病变由专业的足部修剪器记录。在修剪爪子之前和之后评估了说谎行为。挤奶群（n=96）的跛行患病率为32.3％。使用农业和园艺发展局（AHDB）流动性评分系统对流动性进行评分。不同病变组的移动性评分显著不同(p=0.022)。CHDL母牛的平均移动性评分为2.0±0.9（平均值±SD），STL为1.2±1.3,NL为0.9±0.7。与NL躺下时间（11.77±1.67h/d）和站立时间（12.21±1.67h/d）相比，CHDL与更长的躺下时间（15.00±1.04h/d；p=0.0006）和更短的站立时间（9.68±2.38h/d；p=0.0351）相关。STL母牛躺着的时间明显少于CHDL（11.30±2.44；p=0.0013），而不是NL母牛。与任何其他说谎行为没有发现显着差异。修整后,CHDL奶牛躺下的时间明显少于修剪前（13.66±0.98；p=0.0125）。NL的奶牛在修剪后躺下的时间明显更长（12.57±1.90；p=0.0398），并且最小躺下持续时间更短（0.17±0.09；p=0.0236）。总之,奶牛的说谎行为受到蹄病变类型和蹄修剪的影响。
