JAVMA, Vol 230, No. 6, March 15, 2007 T US dairy industry is moving toward fewer dairy farms with more cattle per farm. Between 1995 and 2005, the number of dairy farms decreased by 43.9% (from 139,670 to 78,295), but the total number of milk cows decreased by only 4.5% (from 9.47 to 9.04 million). Consequently, the average herd size for dairies in the United States has almost doubled during th...

In contrast to large, modern confinement dairy systems, management intensive rotational grazing (MIRG) systems can provide a satisfactory income level on a farm that one family can operate with their own labor and management. This is good news for many farm families. What makes the news even better still for these families is that a traditional, Wisconsin dairy farm with average or better manag...

UNLABELLED BACKGROUND Dairy farming is physically demanding and associated with a high frequency of musculoskeletal disorders (MSD). This study investigated and compared work-related MSD, ergonomic work factors and physical exertion in farmers and employed farm workers on dairy farms in Sweden. METHODS The study comprised 66 dairy farmers, and 37 employed dairy farm workers. A modified ver...

Our objective was to determine the role that European starlings (Sturnus vulgaris) play in the epidemiology of Escherichia coli O157:H7 in dairy cattle. We visited 150 dairy farms in Ohio twice during summer and fall months from 2007 to 2009. Fresh faecal pats from 30 lactating cows were collected during each visit. Information on farm management and environmental variables was gathered through...

Women play a significant role in smallholder production system in Pakistan. They actively participate in various activities relating to crop and livestock production in addition to conducting their routine domestic duties often working non-stop from dawn to dusk. But the extent of their participation varies from region to region. The aim of this field survey was to investigate the involvement o...

To investigate the prevalence and characterization of foodborne pathogens [Campylobacter spp., Shiga toxin-producing Escherichia coli (STEC), Listeria monocytogenes and Salmonella spp.] in dairy cows, rectal content grab samples were collected from 250 dairy cows reared on 25 dairy farms in eastern Japan from December 2010 through February 2011. Campylobacter jejuni was isolated from 106 (42%) ...

A cross-sectional comparative study was carried out to investigate the productive and reproductive performances of different genetic groups of crossbred cows at three different farming conditions in Bangladesh. Crossbred cows (n=90) those already completed third lactations, were selected randomly from three different dairy farms (e.g. Jarip, Mullah and Nahar) located in Chittagong, Bangladesh. ...

The study was conducted to develop and evaluate an Indirect Hemagglutination Antibody Test (IHAT) for the serological diagnosis of Cysticercus bovis in live animals. IHAT was set-up inhouse and used to test serum samples of cattle against sheep red blood cell (SRBC) coated with crude extracts of C. bovis cyst. Serum samples for screening were collected from Addis Ababa abattoir (n=522), a dairy...

Computerized information systems can potentially help the dairy producer to deal with the increased complexity of decision making and availability of information in dairy farming. These systems, however, should be fully integrated to ensure a coordinated execution of dairy farming activities. A framework was developed, therefore, to support the creation of computerized management and control sy...
