Post-milking teat protection

Post-milking teat disinfection, is there still something interesting to write about this topic? It has been widely covered since it has been proven to reduce the incidence of new intramammary infections. Although the state-of-the-art is well-known, we are often surprised by how this step is performed daily on the farm. This article will underline the importance of teat disinfection after milking. The worldwide regulatory positioning will give us some insights on how a teat dip is evaluated during the registration process. We’ll have a close look at the EU biocide directive, the main active substances, and other ingredients such as emollients and film forming agents that can be found in the teat dip/spray formulations in order to prevent mastitis. Finally, because post-milking teat disinfection is not effective if not properly applied on the teats, the principles of a correct application will be reviewed. The terms teat dip/teat dip solution/post-milking teat dip (PMTD) or teat disinfectant products will be used equally as general terms to describe solutions applied on the teats after milking.

Impact of nutrition and feeding management on risk of mastitis in dairy heifers

Mastitis risk in dairy cows and heifers is multifactorial and changes with time and interaction with causal factors. This complexity can make it hard to troubleshoot and help farms maintain a low level of mastitis. As a consultant it is difficult to be aware of daily changes and duration of those changes occurring on client dairies.

An update on evidence-based selective dry cow therapy protocols

Dry cow antibiotic therapy (DCT) is the administration of long acting intramammary antibiotics at the time of dry-off. This practice gained widespread implementation in the 1960s as part of the ‘five point plan’ in the UK and numerous clinical trials have demonstrated its efficacy in promoting udder health through the control of intramammary infections (IMI) during the dry period (Halasa et al., 2009a; Halasa et al., 2009b).

Current knowledge and application of biosecurity in cattle

Biosecurity is defined as the combination of all measures that can be taken to reduce the risk of introduction and spread of disease agents between animals. As such, the implementation of biosecurity is an important tool to accomplish disease prevention on cattle farms. It contributes to animal and public health and welfare, but it can also improve economic results and lower antimicrobial use and resistance.

Escherichia coli mastitis

Escherichia coli is a major mastitis pathogen and a well-known cause of clinical mastitis in dairy cows. Ubiquitously present in organic material like manure and bedding, E. coli can reach high concentrations in the cow’s environment. Although being described as generally self-limiting and transient, the infection causes substantial economic lossesRead more

Staphylococcus aureus and bovine mastitis: recent findings

Bovine mastitis is a very common disease in dairy herds worldwide. In Switzerland, the incidence density is 32.7 cases per 100 cow years (Stärk et al., 1997), resulting in total costs of about CHF 130 Mio. per year (Heiniger et al., 2014). Udder diseases are the most common causes forRead more
