background : neospora caninum is considered one of the major causes of repeated abortions in livestock. this study aimed to determine the seropositivity to n. cani-num using indirect elisa and the influence of the infection on the occurrence of abortions in selected dairy herd in slovakia. method: blood samples were obtained from 490 cattle over a period of two years and were tested for n. cani...

The Fleckvieh breed, while internationally recognized as a dual-purpose breed is primarily used as a beef production animal in Ireland. However because of ever increasing pressure to improve efficiency, it is now accepted in Irish cattle breeding that beef production characteristics should be included in the national dairy cattle breeding programme. This development was accepted following a com...

A cross-sectional study with a random cluster sampling design was carried out to estimate the seroprevalence of bovine herpesvirus type 1 (BHV-1) in non-vaccinated dairy herds in Hamedan province, west of Iran. Simple random sampling was used for selection of cattle in each herd. Informative data about each herd and selected animals were recorded by the farm manager in a provided questionnaire....

The competition among dairy producers is sharp nowadays. In this challenging situation the dairies are able to survive by the continuous increase in the efficiency and thereby the profitability of their production. The level of animal health is a basic influential factor of the profitableness on dairy farms, thus, it is very helpful to reveal the herd diseases resulting in the largest economic ...

BACKGROUND Infections with bovine herpesvirus 1 (BoHV-1) and bovine viral diarrhoea (BVD) virus cause diseases of cattle with a worldwide distribution. The primary objective of the present study was to describe aspects of herd-level BoHV-1 and BVDV seroprevalence (based on testing of pooled sera) and control on farms in Northern Ireland, including vaccine usage. An indirect antibody ELISA test ...

A traditional approach in agricultural and veterinary research is focussing on the biological perspective where large cattle-databases are used to analyse the dairy herd. This approach has yielded valuable insights. However, recent research indicates that this knowledge-base can be further increased by examining agricultural and veterinary challenges from other perspectives. In this paper we su...

Mastitis is one of the most important diseases affecting production in dairy cattle. Control strategies against mastitis such as antibiotic therapy, vaccination, improvement of farm and feeding management have met with little success. Genetic variability of mastitis resistance is well established by several independent studies in different breeds of dairy cattle. Usage of somatic cell count or ...

The bulk milk enzyme-linked immune sorbent assay (ELISA) is a rapid and inexpensive method of assessing herd exposure to pathogens that is increasingly being used for the diagnosis of parasite infections in dairy herds. In this paper, with the dairy herd health veterinarian in mind, we review the principles of the assay and the recent literature on the potential role of bulk milk ELISA for the ...

Schmallenberg virus (SBV) is a recently emerged Orthobunyavirus of ruminants originally discovered in 2011 near the town of Schmallenberg in Germany (Hoffmann and others 2012). SBV appears to have entered Europe in the summer of 2011 and has since spread rapidly across much of central and northern Europe. Seroprevalence in some areas has been reported close to 100 per cent (Tarlinton and others...

Materials and Methods The estimate of world buffalo population is approximately 185.29 million dispersed in 42 countries, out of which 97% (179.75 million) are found only in Asia [1]. India has approximately 57% (105.3 million) of the total world buffalo population. The water buffalo ( ) contributes immensely to the agricultural economy through milk, meat, hides and draught power [2]. Share of ...
