Summary:
A study evaluated an essential oil mixture for the treatment of bovine mild and moderate clinical mastitis in dairy cattle. In dairy herds from Brittany, Pays de la Loire or Auvergne Rhône Alpes, a total of 131 clinical cases were randomly assigned to essential oil (n = 72) or antibiotic (n = 63) group. Essential oil mixture was applied on infected quarter during 14 consecutive milking. Results showed that clinical cure rate was lower in the essential oil group than in antibiotic group (72.3 % vs 88.1 %). Cure rate based on two consecutive individual SCC < 300 000 cell/ml after occurrence was higher in essential oil group only in Brittany, Pays de la Loire (95.0 % vs 60.0 %). Bacteriological cure rate was lower in essential oil group compare to antibiotic group only in Auvergne Rhône Alpes (96.0 % vs 53.4 %). In the growing context of antimicrobial resistance, results showed that there is an interest to consider essential oils as a complement to antibiotics to evaluate new treatment strategies of dairy cows mammary infections.

Summary:
Selective Dry Cow Therapy (SDCT) is becoming more common on many dairy farms in response to increasing pressure to use antibiotics responsibly in agriculture, as well as the demands from milk buyers and supermarkets. Trials have shown that cows with no evidence of existing infection within the udder can be successfully dried off with only a teat sealant. The use of antibiotic dry cow therapy can then be targeted to only those cows with evidence of infection at dry off—usually indicated by a high somatic cell count in late lactation.

Milk acidification to control the growth of Mycoplasma bovis and Salmonella Dublin in contaminated milk by Parker, A.M., House, J.K., Hazelton, M.S., Bosward, K.L., Mohler, V.L., Maunsell and P.A. Sheehy 2016 Journal of Dairy Science 99: 9875–9884

Species targeted: Dairy;
Age: Young;
Summary:
Bacterial contamination of milk fed to calves compromises calf health. Several bacterial pathogens that infect cows, including Mycoplasma bovis and Salmonella enterica ssp. enterica serovar Dublin, are shed in milk, providing a possible route of transmission to calves. Milk acidification lowers the milk pH so that it is unsuitable for bacterial growth and survival. The objectives of this study were to (1) determine the growth of M. bovis and Salmonella Dublin in milk, and (2) evaluate the efficacy of milk acidification using commercially available acidification agent (Salstop, Impextraco, Heist-op-den-Berg, Belgium) to control M. bovis and Salmonella Dublin survival in milk. Results demonstrate that milk acidification using Salstop is effective at eliminating viable M. bovis and Salmonella Dublin organisms in milk if the appropriate pH and exposure time are maintained.

In Significant Impact Groups: Specific alternatives
Species targeted: Dairy;
Age: Adult;
Summary:
In the present study, we showed the protective effect of Zophobas morio (Z. morio) hemolymph on bovine mammary epithelial cells against bacterial infection. Z. morio hemolymph directly kills both Gram-positive and Gram-negative bacteria through membrane permeation and prevents the adhesion of E. coli or the clinically isolated S. simulans strain to bovine mammary epithelial (MAC-T) cells. In addition, Z. morio hemolymph downregulates the expression of nucleotide-binding oligomerization domain (NOD)-like receptor family member pyrin domain-containing protein 3 (NLRP3), caspase-1, and NLRP6, as well as inhibits the secretion of interleukin-1 beta (IL-1 beta) and IL-18, which attenuates E. coli or S. simulans-induced pyroptosis. Overall, our results suggest the potential role of Z. morio hemolymph as a novel therapeutic candidate for bovine mastitis.

Species targeted: Dairy;
Age: Adult;
Summary:
The etiological agents of Bovine mastitis include a variety of gram-positive and gram-negative bacteria, and can be either contagious (e.g., Staphylococcus aureus, Streptococcus agalactiae, Mycoplasma spp.) or environmental (e.g., Escherichia coli, Enterococcus spp., coagulase-negative Staphylococcus, Streptococcus uberis). The extensive use of antibiotics increased concerns about emergence of antibiotic-resistant pathogens and that led the dairy industries to reduce the use of antibiotics. This review provides an overview of bovine mastitis in the aspects of risk factors, control and treatments, and emerging therapeutic alternatives in the control of bovine mastitis.

331 Research paper – Swinkels – 2015 – Social influences on the duration of antibiotic treatment of clinical mastitis in dairy cows

In Significant Impact Groups: AMU reduction strategies \ Prudent use AB
Species targeted: Dairy;
Age: Adult;
Summary:
The aim of this study was to explore the social factors influencing farmers’ decision-making on the duration of antibiotic treatment of clinical mastitis. Extended treatment is perceived as part of the social norm of “being a good farmer.” The participants’ perception was that mastitis is not treated “thoroughly” if clinical symptoms were still visible at the time of cessation of treatment. Groups with whom the farmer identifies and regularly communicates face to face, such as other farmers, the herd veterinarian, and other farm advisors, confirm the farmer’s judgment on extending treatment and influences him or her toward socially accepted behavior. Legislation may reduce antibiotic usage, if doable and controllable. Evidence-based information on treatment efficacy or practical on-farm decision support indicating when to end treatment may be able to change social norms of “thorough” treatment, especially when communicated by a group such as veterinarians.

In Significant Impact Groups: AMU reduction strategies \ Monitoring and surveillance Antibiotic use
Species targeted: Dairy;
Age: Young; Adult;
Summary:
This study analyzes database recordings of milk yield and somatic cell count from routine milk recording schemes, clinical registrations of mastitis, and cow factors such as days in milk and parity in relation to antibiotic treatments for 518 dairy herds in Denmark. Analysis was performed to identify the driving predictors for treatment in different groups of farms. The results showed that determinants that were most important for predicting antibiotic treatments vary from one farm to another. Health indicators such as test results or somatic cell count were most indicative for treatment on some farms, whereas other groups seemed to depend more on production factors (milk yield) or later culling of the cows. This shows that farmers behave differently and differences can be identified in register data. This information can be considered when developing cost-effective herd-specific control measures of mastitis to promote prudent use of antibiotics in Danish dairy cattle farms.
