Assessing Milk Production and Quality during Mastitis Caused by a Variety of Pathogens in Dairy Cows
To affect future management efforts, understanding how mastitis affects milk at the genus-species level of the causing pathogen is critical. The goal of the current study was to establish a connection between a specific genus or species of pathogens that cause mastitis in cows and variations in the quantity and composition of their milk. A lone cow from a commercial dairy farm near Mount Gambier, South Australia, Australia, was the focus of the experiment (n = 2,676). On samples of milk, a standard microbiological culture was conducted. Using data from herd testing, production indicators for each cow, including yield, fat, total milk solids and protein percentages, and somatic cell count, were gathered into a database. The outcomes revealed isolated five different pathogens from milk at the genus or species level. The objective of the current study was to determine a relationship between a certain genuses or species of pathogens that cause mastitis in cows and changes in the amount and makeup of their milk. The quantity and quality of milk were impacted by each specific infection. S. aureus had the greatest impact on milk production. Similarly, Enterococcus species have the biggest impact on SCC. Escherichia coli, however, had a minor to insignificant impact on the amount and composition of milk. Because mastitis pathogens vary between geographic regions and historical periods, the findings of the current study will have an impact on how bovine mastitis is managed.
