In order to meet the requirement of dairy cattle breeding and modern cattle farm management, the dairy cattle registration and herd management system was programmed with Visual FoxPro9.0, which can run on Windows9X/Me/NT/2000/XP, to fit the current implemented Canadian dairy cattle DHI recorders and 9-point linear comprehensive evaluation. Based on data collection and analysis of basic herd inf...

bovine neosporosis caused by the apicomplexan protozoan parasite n. caninum, was initially recognized in 1989 and is now reported as a leading infectious cause of reproductive failure in dairy cattle in world wide. the aim of this study was to determine the seroprevalence of n. caninum infection in industrial dairy cattle of hamedan province (west of iran) by elisa method. blood samples were co...

BACKGROUND Mycobacterium avium subsp. paratuberculosis (MAP) infections in cattle are generally challenging to detect and cost-effective test strategies are consequently difficult to identify. MAP-specific antibody ELISAs for milk and serum are relatively inexpensive, but their utility is influenced by a number of factors such as herd size, herd composition and diagnostic sensitivity. The sensi...

Between 2007 and 2009, the largest human Q fever epidemic ever described occurred in the Netherlands. The source was traced back to dairy goat farms, where abortion storms had been observed since 2005. Since one putative cause of these abortion storms is the intensive husbandry systems in which the goats are kept, the objective of this study was to assess whether these could be explained by her...

Dairy cattle raising has been developing rapidly although there were some troubles. Total dairy herd was more than 110,000 heads in the whole country, of which there were 59,958 heads in Ho Chi Minh City (June, 2006). It exceeded the Governmental plan for dairy development. However, some provinces could not keep their dairy development program continuously. They had invested on many aspects con...

The objective of this study was to determine the seroprevalence of paratuberculosis in dairy cattle in Burdur province located in southwest of Turkey. Blood samples were collected and tested by the enzyme linked immunosorbent assay (ELISA) from 465 dairy cattle older than 2 years randomly selected from 24 dairy cattle herds. Seroprevalence of paratuberculosis was found in 6.2% at the individual...

this experiment was conducted to evaluate reproductive indices and provide appropriate solutions to improve the reproductive efficiency of dairy cattle in kermanshah province. with reference to forty-eight dairy industrial herds available at different cities of the province, a questionnaire containing quantitative measures were completed to assessing the reproductive parameters of 5397 dairy co...
