“…The locomotion score can be used to classify the condition of a cow based on how well it moves. 21,22 There was no significant difference in lameness (locomotion score >2) between the QASD and CZS groups at the end of the study period. This might be because some cows suffered from double soles, sole ulcers, sole haemorrhages (circumscribed) or white line disease, and both the QASD and CZS groups had new incidences of sole ulcers or white line disease at the end of the trial.…”

“…20 Locomotion scoring in cattle with DD is a useful tool for tracking lameness over time and identifying cattle requiring intervention. 21 In addition, a locomotion score can be used to classify the condition of a lame cow. 22 The objective of this study was to determine if a QASD footbath was more effective than a CZS solution for treating DD in lactating Holstein cows.…”

BackgroundFootbaths can be used to manage digital dermatitis (DD), a common cause of lameness in dairy cattle. Copper sulfate and chelated copper–zinc (CZS) solutions in footbaths are potentially harmful to the environment.Hypothesis/ObjectivesTo determine if a quaternary ammonium salt‐based disinfectant (QASD) footbath is as effective as a chelated CZS solution in controlling DD in dairy cows.AnimalsFifty‐one lactating Holstein cows were randomly assigned to one of two treatment groups, with DD status based on the M‐stage scoring system and locomotion score balanced between treatment groups.Materials and MethodsThe groups were treated with a 1% QASD or a 2.5% chelated CZS. Footbaths were performed once per week for 15 weeks. Logistic regression was used to analyse clinical improvement. All cows received appropriate medical treatment for DD and other hoof diseases.ResultsClinical improvement rates were 67% in the QASD group and 38% in the CZS group (p = 0.03). Logistic regression analysis showed that the odds (95% confidence interval) for clinical improvement rate in the CZS group were 0.30 (0.095–0.948) times that of the QASD group (p = 0.04). The M0 score in the QASD and CZS groups increased significantly (p < 0.05) at the end of the 15 week study period. In the QASD group, the proportion of M2, M3 and M4 scores were significantly decreased (p < 0.05).Conclusion and Clinical RelevanceOver a 15 week period, QASD for footbathing was associated with a lower prevalence of active DD lesions than when using CZS.

“…It was rst identi ed in dairy herds in Italy in seventies and has become endemic in dairy herds worldwide since then with variable prevalence being reported (21). Although DD was not always associated with altered locomotion, studies have found that cattle identi ed with DD lesions were 8 and 10 times more likely to be diagnosed as either lame or moderately to severely lame compared with cattle without lesions, respectively (22). DD was the most treated foot lesion by hoof care professionals in the USA (23).…”

Background lameness is a significant problem of the dairy industry worldwide. No previous studies have evaluated the prevalence of lameness or digital dermatitis (DD) in dairy cattle herds in Egypt. A total of 16,098 dairy cows from 55 dairy herds in 11 Egyptian Governorates underwent visual locomotion scoring using a 4-point scoring system. Cows that had a lameness score ≥ 2 were considered clinically lame. Following manure removal with water and using a flashlight, the cows’ hid feet were examined in the milking parlour to identify and M-score DD lesions. Furthermore, each cow was assigned a hock score (a 3-point scale) and a hygiene score (a 4-point scale). The cow-level, within-and between-herd prevalence of lameness and digital dermatitis and associated 95% confidence intervals (CI) were calculated. The prevalence of hock lesions and poor cow hygiene was also calculated. Results Of the examined cows, 6,883 cows were found to be clinical lame (42.8%, 95% CI = 42–43.5%). The average within-herd prevalence of lameness was 43.1% (95% CI = 35.9–50.3%). None of the dairy herds recruited into the study was found to be free from clinical lameness. The average within-herd prevalence of DD was 6.4% (95% CI = 4.9–8%). The herd-level prevalence of DD was 92.7% (95% CI = 85.9–99.6%). Active DD lesions (M1, M2, M4.1) were identified in 464 cows (2.9%) while inactive lesions (M3, M4) were identified in 559 cows (3.5%). The within-herd prevalence of hock lesions (score 2 or 3) was 12.6% (95% CI = 4.03–21.1%) while a severe hock lesion had within-herd prevalence of 0.31% (95% CI = 0.12–0.51%). Cow-level prevalence of hock lesions was 6.2% (n = 847, 95% CI = 5.8–6.2%). Majority of examined cows had a hygiene score 4 (n = 10,814, prevalence = 70.3%, 95% CI = 69.5–71%). Conclusions The prevalence of lameness was higher than reported prevalence estimates in other countries which could be due to differing management and/or environmental factors. DD was identified at lower prevalence in most herds. Poor cow hygiene was notable in most herds. There should be measures to reduce the prevalence of lameness and to improve cow hygiene in dairy cattle herds in Egypt.

A total of 16,098 dairy cows from 55 dairy herds in 11 Egyptian governorates underwent visual locomotion scoring using a 4-point scoring system. Cows that had a lameness score ≥ 2 were considered clinically lame. Following manure removal with water and using a flashlight, the cows’ hind feet were examined in the milking parlour to identify DD lesions and classify with M-score. Furthermore, each cow was assigned a hock score (a 3-point scale) and a hygiene score (a 4-point scale). The cow-, within-and between-herd prevalence of lameness and DD and associated 95% confidence intervals (CI) were calculated. The prevalence of hock lesions and poor cow hygiene was also calculated. Results Of the examined cows, 6,883 were found to be clinically lame (42.8%, 95% CI = 42.0–43.5%). The average within-herd prevalence of lameness was 43.1% (95% CI = 35.9–50.3%). None of the dairy herds recruited into the study were found to be free from clinical lameness. The average within-herd prevalence of DD was 6.4% (95% CI = 4.9–8.0%).

Cow-level prevalence of hock lesions was 6.2% (n = 847, 95% CI = 5.8–6.2%). The majority of examined cows had a hygiene score of 4 (n = 10,814, prevalence = 70.3%, 95% CI = 69.5–71%). Conclusions The prevalence of lameness was higher than prevalence estimates reported for other countries which could be due to differing management and/or environmental factors. DD was identified at lower prevalence in most herds but with high herd-level prevalence. Poor cow hygiene was notable in most herds. Measures to reduce the prevalence of lameness and to improve cow hygiene in dairy cattle herds in Egypt are therefore needed.
