dairy farmers have been longing for simple and economical methods of early pregnancy diagnosis. urine based biochemical and mineral assays could be one of those methods, owing to the ease of sample collection and relatively simple and economical assays involved. however, basic information on changes in urinary composition during early pregnancy in cattle is lacking. this study was designed to e...

This study aimed to analyze the financial impact of foot-and-mouth disease (FMD) outbreaks in cattle at the farm-level and the benefit-cost ratio (BCR) of biannual vaccination strategy to prevent and eradicate FMD for cattle in South Vietnam. Production data were collected from 49 small-scale dairy farms, 15 large-scale dairy farms, and 249 beef farms of Long An and Tay Ninh province using a qu...

BACKGROUND Bovine brucellosis remains one of the most prevalent zoonotic infections affecting dairy cattle in developing countries where the applied control programs often fail. We analyzed the epidemiologic pattern of bovine brucellosis in a dairy cattle herd that showed several cases of abortions after regular vaccination with RB51 (B. abortus vaccine). In 2013 thirty dairy cows, from a Holst...

OBJECTIVE To describe antimicrobial susceptibility patterns in Campylobacter spp isolated from dairy cattle and farms managed organically and conventionally in the midwestern and northeastern United States. DESIGN Longitudinal study. SAMPLE POPULATION 128 farms. PROCEDURE Samples and data were collected every 2 months from August 2000 to October 2001. Fecal samples were collected from cal...

Streptococcus agalactiae is an emerging pathogen of nonpregnant human adults worldwide and a reemerging pathogen of dairy cattle in parts of Europe. To learn more about interspecies transmission of this bacterium, we compared contemporaneously collected isolates from humans and cattle in Finland and Sweden. Multilocus sequence typing identified 5 sequence types (STs) (ST1, 8, 12, 23, and 196) s...

UNLABELLED Bovine tuberculosis is an ongoing problem in Ireland, and herd incidence has remained at approximately 5% for some years. Spillover of infection from cattle to people remains an ever-present possibility, given the ongoing pool of infection in the Irish cattle population. This paper describes an outbreak of tuberculosis affecting cattle and people on a dairy farm in southeastern Irela...

BACKGROUND Mortality risk in Danish dairy cows has more than doubled since 1990 (from 2% in 1990 to 5% in 2005). Until now, registrations about dead cows in the Danish Cattle Database have not included information about whether the cow died unassisted or was euthanized. METHODS We interviewed a random sample of 196 Danish dairy farmers that had reported a dead cow to the Danish Cattle Databas...

staphylococcus spp., is a common bacteria in cattle mastitis. detection of the low number of bacteria requires a sensitive method. we used multiplex polymerase chain reaction (m-pcr) assay to detect the genes encoding sea, seb, sec toxins, that are specific in s. aureus bacteria. the gene of 23s rrna that is conserved in all staphylococcus spp., also was used. due to the stiffness and low effec...
