This cross-sectional study is the first to estimate the prevalence of cattle pediculosis in Tunisia. A total of 39 cattle farms in the region of Nabeul in north-east Tunisia were visited and lice were collected by intensively brushing 789 cattle. The prevalence was estimated to be 20.5% on the farms (8/39) and 4.7% in animals (37/789). Collected parasites were examined under a stereomicroscope ...

An epidemic of high pathogenicity Avian Influenza (HPAI) occurred in the Netherlands in 2003. A census survey of 173 infected and 401 uninfected commercial poultry farms was carried out to identify factors associated with the introduction of the HPAI virus into poultry farms. Data on farm size, production characteristics, type of housing, presence of cattle and pigs were gathered by the Nationa...

in order to investigate the prevalence of infection with bovine viral diarrhoea virus(bvdv) of cattle in ahvaz,blood samples were collected from jugular vein of 572 cattle(521 female, 51 male) from industrial and nonindustrial farms. sera were stored at -20?c while waiting for analysis. the sera were tested by elisa, using a commercial elisa kit for detection of specific antibody to bovine vira...

The research evaluated the feasibility of centralised pre-processing and pasteurisation of source-separated domestic food waste followed by transport to farms for anaerobic codigestion with dairy cattle slurry. Data from long-term experiments on the co-digestion of these two substrates was used to predict gross energy yields; net yields were then derived from full system analysis using an energ...

Stephen T. Morris Institute Veterinary, Animal and Biomedical Sciences, Massey University, Private Bag 11222, Palmerston North 4410, New Zealand ABSTRACT: The New Zealand climate favours pasture growth, and it is the key to sheep and beef cattle production as pasture provides over 95% of the diet of sheep and beef cattle. Production systems range from intensive sheep and beef cattle farms on th...

Escherichia coli O157 infections are the cause of sporadic or epidemic cases of often bloody diarrhea that can progress to hemolytic uremic syndrome (HUS), a systematic microvascular syndrome with predominantly renal and neurological complications. HUS is responsible for most deaths associated with E. coli O157 infection. From March 2002 to February 2004, approximately 13,000 fecal pat samples ...

Biosecurity is crucial for safeguarding livestock from infectious diseases. Despite the plethora of biosecurity recommendations, published scientific evidence on the effectiveness of individual biosecurity measures is limited. The objective of this study was to assess the perception of Swiss experts about the effectiveness and importance of individual on-farm biosecurity measures for cattle and...

In this study, we examined the prevalence and molecular characteristics of Cryptosporidium in buffalo, dairy cattle and sheep in different farms at Kafr El Sheikh Province, Egypt. Rectal fecal samples, including 466 samples from buffalo, 1697 from cattle and 120 from sheep, were collected from different ages and screened by modified Ziehl-Neelsen acid-fast microscopy for detection of Cryptospor...

Sections from cattle hair serve as an isotopic archive-they contain information on the cattle diet from different time periods. We tested the reliability of 13C signatures (δ13C) in cattle tail switch hair to retrospectively trace back the annual dietary proportion of maize of different production systems without having to sample and analyze the feed. Furthermore, we investigated if differences...

Rift Valley fever is a vector-borne zoonotic disease which causes high morbidity and mortality in livestock. In the event Rift Valley fever virus is introduced to the United States or other non-endemic areas, understanding the potential patterns of spread and the areas at risk based on disease vectors and hosts will be vital for developing mitigation strategies. Presented here is a general netw...
