Big data and machine learning tools to understand mastitis epidemiology and other topics
… of technologies to collect and store individual health data is leading to a growing interest in applying Big Data analytical methodologies to better understand health and disease in both humans and dairy cattle. Data collected through routine observations such as doctor or veterinary visits, …

WATER BUFFALO MILK CHAIN IN BANGLADESH
The present study aimed to assess udder health by estimating the prevalence of subclinical mastitis (SCM) and identifying intramammary infection (IMI) causing pathogens. Furthermore, milk quality was evaluated by measuring bulk milk somatic cell count (BMSCC) on buffalo farms and total bacterial …

Escherichia coli Mastitis in the Dairy Bovine
… between treatment groups as a measure of udder health. Serum a-lactalbumin concentrations were higher in cows in the EC-NT treatment group than cows in the NI-NT, NI-FMO and EC-FMO treatment groups at 12 hours post-experimental challenge. Serum a-lactalbumin concentrations were higher in …

Genetic Parameter Estimates of Milkability Traits in South African Holstein Cattle
… which milk can be completely drawn from a cow’s udder. It is an important functional trait with regard to milking costs as well as udder health. Milkability traits have not been included in the breeding objectives of South African dairy cattle and their genetic parameters in the population have …

Effects of Outdoor Access and Season on Mastitis Pathogen Distribution and Milk Quality Parameters in Dairy Herds in Western Canada
… dairy production systems, housing practices, and udder health determinants, (2) a multi-pathogen epidemiologic study evaluating associations between pathogen distribution and housing system, province, and season in AB and BC herds, and (3) a general discussion integrating biological mechanisms, …

Local Regulation of Milk Synthesis Capacity in the Mammary Gland of Lactating Dairy Cows
… the implementation of IMF with 2x and 4x udder halves at early and mid-lactation for 21 and 20 d on milk yield (MY) and its association with changes in cistern and alveolar capacity. Results showed that udder halves milked 4x produced 2.27 kg more MY. Additionally, cows milked during early …

USE OF ON-FARM DATA AND MILK LEUCOCYTE COMPONENTS FOR MONITORING THE HEALTH OF DAIRY COWS
The aim of this PhD project was monitoring cow health and welfare, using on-farm data and leucocytes components in milk. For this reason, the investigation focused on the two main diseases of dairy cows: mastitis and lameness. Critical aspects are linked with these diseases and some of them were …

MAPPING GENOMIC VARIANTS ASSOCIATED WITH FUNCTIONAL AND HEALTH TRAITS IN DAIRY CATTLE POPULATION
… investigate genetic variability, resilience, and udder health in Holstein dairy cattle. By combining genomic tools, sensor-derived time series, and veterinary treatment records, the study provides a multidimensional view of animal functionality under real farming conditions. The first chapter, …

Photon migration in highly scattering media as a measurement technique on automated cow milking systems
… used in the dairy industry to monitor udder health and mastitis. Since milk is a highly scattering medium, one needs to choose a suitable mathematical model to characterise it so that quantitative measurements can be made. The diffusion approximation, a simplified version of transport …
