BACKGROUND Acute puerperal metritis (APM) affects 30% of postpartum dairy cattle. Bacteremia negatively impacts survival in cattle with coliform mastitis. However, the prevalence of bacteremia in dairy cattle with APM is unknown. HYPOTHESIS Bacteremia is detectable in a large proportion of cattle with APM. ANIMALS Seventeen dairy cows with APM and 17 healthy dairy cattle. METHODS Prospect...

Neospora caninum is now recognized as a major cause of abortion in cattle worldwide, but there is no report of N. caninum infection in cattle in India. Serum samples from 427 dairy cattle and 32 dairy water buffaloes from 7 organized dairy farms located in Punjab, India, were tested for N. caninum antibodies using a commercial monoclonal antibody-based competitive enzyme-linked immunosorbent as...

SUMMARY In this study, Coxiella burnetii seroprevalence was assessed for dairy and non-dairy sheep farm residents in The Netherlands for 2009-2010. Risk factors for seropositivity were identified for non-dairy sheep farm residents. Participants completed farm-based and individual questionnaires. In addition, participants were tested for IgG and IgM C. burnetii antibodies using immunofluorescent...

Both conventional and organic dairies rely on vaccination programs to help prevent infectious diseases in their cattle. However, it could be argued that maximizing every bit of benefit from a vaccination program is even more crucial in organic dairy operations since treatment alternatives are more limited. Vaccination of organic dairy cattle is allowed for certification. But within that allowan...

The calculation and publication of all dairy cattle genetic evaluations in Canada is the responsibility of Canadian Dairy Network (CDN). An 8-member board of directors, the majority being dairy producers, governs this non-profit national organization. Member organizations include all breed associations, milk recording agencies and artificial insemination centres across Canada as well as Dairy F...

While cattle in general have been identified as a reservoir of Escherichia coli O157:H7, there are limited data regarding the prevalence and clonality of this pathogen in downer dairy cattle and the potential impact to human health that may occur following consumption of meat derived from downer dairy cattle. In the present study, conducted at two slaughter facilities in Wisconsin between May a...

Triclabendazole (TCBZ) is the drug of choice for Fasciola hepatica control and reports of F. hepatica resistant to this drug from a wide range of geographic regions are very concerning. This study investigated the presence of TCBZ resistance in F. hepatica in naturally infected Australian beef and dairy cattle herds and evaluated methods of measuring the levels of resistance. Faecal egg count a...

Increasing feed costs and the desire to improve environmental stewardship have stimulated renewed interest in improving feed efficiency of livestock, including that of US dairy herds. For instance, USDA cost projections for corn and soybean meal suggest a 20% increase over 2010 pricing for a 16% protein mixed dairy cow ration in 2011, which may lead to a reduction in cow numbers to maintain pro...
