Abstract

Bovine mastitis is the most frequent disease worldwide in dairy herds, causing high economic losses to producers and industry, as well as having implications for public health due to the zoonotic potential of some agents involved in its etiology and the increased risk of antimicrobial residues in...

Abstract

The aim of this study was to estimate the economic impact of mastitis at the herd level and the weight (percent) of the components of this impact in a Holstein dairy herd under tropical conditions. Three estimates of the economic impact of mastitis were performed. In estimates 1 and 2 the real...

Abstract

The objectives of this study were to estimate the herd prevalence of major mastitis pathogens in bulk tank milk (BTM) in China dairy herds, to determine the relationship between the presence of mastitis pathogens and bulk tank milk somatic cell counts (BTSCC), and to investigate the impact of...

Abstract

The objective of this study was to determine the lipolytic activity on milk fat of 2 bovine mastitis pathogens, that is, Staphylococcus aureus and Streptococcus agalactiae. The lipolytic activity was determined by 2 different techniques, that is, thin-layer chromatography and an...

Abstract

The aim of this study was to compare the effects of cryopreservation at approximately -196°C in liquid nitrogen (N) and freezing at approximately -20°C in a freezer, on the viability and survival of eight different mastitogenic bacteria inoculated in milk. Bacteria were frozen at approximately...

Abstract

When designing mastitis-prevention and control programs, it is important to know the level of adoption of mastitis-prevention management practices and control programs and the herd-level prevalence of contagious mastitis pathogens. Our objectives were to estimate: (1) adoption of recommended...

Abstract

The Gesan programme that has been in operation in Italy since 2000 has enabled an epidemiological model for intra-mammary infections (IMI) to be developed and the incidence of IMI to be reduced, thus bringing about improvements in milk quality. The main objectives of the Gesan programme are: (1)...

Abstract

The value of treating cows at the end of lactation with cloxacillin was assessed in two herds comprising 310 cows. There was a great reduction in the level of staphylococcal infection in the udders and in individual quarters. New staphylococcal infections were also reduced, and Streptococcus...

Abstract

The incidence of pathogenic organisms in milk, and clinical mastitis, was recorded in three dairy herds which had been regularly sampled from 1951 until 1964. Routine herd tests were performed at 3 to 6-monthly intervals throughout the period. Following an eradication programme, the herds were...
