Technopaties in dairy cows: Peritarsal lesions

Abstract

Technopathies in dairy cows represent a complex interplay between technological advancements, management practices, and animal health. While technological innovations have undoubtedly improved efficiency and productivity, they also introduce new challenges, particularly in relation to the health and welfare of dairy cows. Lameness associated with claw pathology is one of a prevalent technopathy in dairy cows. However, it can be associated also by other pathologies, including peritarsal lesions. This paper aims to explore the peritarsal lesions in dairy cows, their prevalence in selected Slovenian herds and their connection to flooring and cubicle type. Tarsal region was evaluated in 16 dairy herds in NE Slovenia. We assessed 881 dairy cows. Type (alopecia, erosions, decubitus, swelling) and size (up to 3 cm2 , < 20 cm2 , < 50 cm2 and >50 cm2 ) of lesions were documented. In all herds type of flooring and cubicles were recorded including their size and occupancy %. Results were statistically evaluated using descriptive statistics, correlations and ANOVA analysis. Significance was set at p<0.05. Out of 881, 373 (42.3%) had peritarsal lesions. The prevalence on herd level was from slightly above 2 to more than 70%. We noticed that peritarsal lesions are more prevalent in herds with high cubicles, than in those with deep cubicles. Cubicle occupancy rate statistically non-significantly influenced peritarsal health. Results of the study surprised us, as we have expected far lower prevalence of peritarsal lesions. A positive fact is that we also had a herd with very favorable status concerning hock lesions, which proves that much better situation in this issue can be achieved. Collaborative efforts among researchers, veterinarians, and farmers are essential for identifying key issues leading to technopathies, implementing effective mitigation strategies, and promoting sustainable dairy farming practices.
