Description

Aim of the study was to determine the prevalence of bovine norovirus and nebovirus infections in dairy calves in Sweden. A secondary aim was to analyse herd and management factors associated with these infections. In this study, samples and data collected for another study in 2005-2007 were used (Silverlås et al. 2009. Prev. Vet. Med. 90, 242-253). The samples and data were originally collected for studying Cryptosporidium infections. Fecal samples from 5 calves 2-30 days of age were collected by a veterinarian visiting each farm once, in total 50 farms. For the present study, samples were analysed by RT-PCR for bovine norovirus and nebovirus. For specification of the methods, see the published paper. The management data were collected at the farm visits by observation and interview of farmers using a standardized questionnaire.

Probability
50 dairy herds were randomly selected from a list of all dairy herds with >50 cows in the 5 geographic regions of the study, in proportion to the no. of herds in each region. Five calves aged 2-30 days were sampled per herd. For more information on the selection of calves, see the published paper.

Prevalence of bovine norovirus and nebovirus and risk factors for infection in Swedish dairy herds

Description

The dataset contains the results of RT-PCR analyses of fecal samples from young calves for bovine norovirus and nebovirus. Five calves per herd in 50 Swedish dairy herds were included in the study. The dataset also includes information about the herd, i.e. herd size, average yearly production and a number of variables concerning management of calvings and calves. Such management routines could influence the level of calf health and transmission of infections. These data were gathered through sta
