Milk is synthesised in epithelial cells of the mammary gland and is virtually sterile when secreted into the alveoli of the udder. Recent research indicates a general tendency for bulk tank TBC in Ireland to decrease between the years of 1994 to 2003, but this was followed by an increase between 20. Additionally, incentives (TBC less than 30,000) and penalties are applied by milk processors to help ensure high milk quality. Accordingly, milk quality is required to be within certain thresholds according to European law (, Council Directive 92/46/EEC) total bacterial count must not exceed a geometric average of 100,000 per ml over two months, with at least two tests per month. coli can spoil milk and dairy products by gas production during storage. For example, Alteromonas putrefaciens causes a surface taint in butter, and E. Bacteria can also have a negative effect on dairy products. After pasteurisation, the risk of illness to humans can occur by recontamination of milk through milk pipes and stored milk residues or by thermoduric bacteria ( Bacillus cereus) which can survive pasteurisation. High TBC milk should be avoided since some bacteria ( Staphylococcus aureus, Escherichia coli and Streptococcus agalactiae) found in raw milk can cause diarrhoeal disease and food poisoning. Total bacterial count (TBC) is the bacteria growth per ml of milk over a fixed period of time. Herd management factors associated with bulk tank TBC in Irish grazing herds were generally in agreement with most previous studies from confinement systems of milk production. Increased level of hygiene of the parlour and cubicles were also associated with lower TBC. Results from the multivariate analysis indicated that the following management practices were associated with low TBC use of heated water in the milking parlour participation in a milk recording scheme and tail clipping of cows at a frequency greater than once per year. Median bulk tank TBC for the sample herds was 18,483 cells/ml ranging from 10,441 to 130,458 cells/ml. A multiple stepwise regression model was subsequently developed. All herd management factors were individually analysed in a separate regression model, that included an adjustment for geographical location of the farm. Herd management factors associated with bulk tank TBC were identified using linear models with herd annual total bacterial score (i.e., arithmetic mean of the natural logarithm of bulk tank TBC) included as the dependent variable. The relationship between bulk tank TBC and farm management and infrastructure was examined using data from 400 randomly selected Irish dairy farms where the basal diet was grazed grass. The objective of the current study was to quantify the associations between herd management factors and bulk tank TBC in Irish spring calving, grass-based dairy herds.
