Lameness is a severe welfare problem and production-limiting disease in dairy farming. The objectives of this study were to determine prevalence lameness investigate cow- herd-level factors associated with cows housed freestall barns 3 Canadian provinces. A purposive sample 40 Holstein-Friesian was selected from each 141 farms Québec, Ontario, Alberta. In total, 5,637 scored once for (presence limping when walking). Data collected included information on individual (hock lesions, claw...
Lying behavior is an important measure of comfort and well-being in dairy cattle, changes lying are potential indicators predictors lameness. Our objectives were to determine individual herd-level risk factors associated with measures behavior, evaluate whether automated can be used detect A purposive sample 40 Holstein cows was selected from each 141 farms Alberta, Ontario, Québec. 5,135 between 10 120 d milk automatically continuously recorded using accelerometers over 4 d. Data on...
Mastitis is a highly prevalent disease, which negatively affects cow performance, profitability, welfare, and longevity. The objectives of this study were (1) to quantify the impact first instance mastitis, at different stages lactation, on production economic (2) further mastitis when only cows that remain in herd for least 100 d milk (DIM) those 305 DIM are included analysis. A retrospective longitudinal was conducted using data from existing animal health record files Dairy Herd...
Abstract Obtaining reliable welfare outcome measures from commercial farms can be challenging. We developed a training programme to train observers score injuries of the tarsal joint, carpal joint and neck on dairy cows as part an on-farm study. Twelve trainees were trained using protocols photographs in classroom session visits. Continued repeatability checking was carried out during refresher mid-way assessment. Two trainers used reference standard which all compared. The study...
Animal welfare has become a critical issue in contemporary society, emphasizing our ethical responsibilities toward animals, particularly within livestock farming. The advent of Artificial Intelligence (AI) technologies, specifically computer vision, offers an innovative approach to monitoring and enhancing animal welfare. Cows, as essential contributors sustainable agriculture, are central this effort. However, existing cow detection algorithms face challenges real-world farming...
Intensification in animal production has led to increased indoor confinement for animals, limiting opportunities meet some behavioral needs such as exploration and locomotion. This poses a crucial question how these restrictions can be alleviated by providing additional space designed with that specific purpose mind. Working cows housed tie-stalls, our study aimed to: (1) quantify an exercise area outside the normal housing environment affects locomotor behavior; (2) evaluate access...
