Background: Biting midges in the genus Culicoides (Diptera: Ceratopogonidae) act as vectors for several arboviruses, including Bluetongue virus (BTV) and Schmallenberg (SBV), which affect livestock health productivity. In Ireland, limited genetic data are available regarding diversity of species. This study represents first attempt to characterise this region using molecular techniques. Methods: Adult samples were captured Onderstepoort Veterinary Institute (OVI) traps across six locations...

Calf output is a key element in determining the profitability of suckler beef enterprise. Infectious agents such as Bovine Virus Diarrhoea (BVD) virus, colostrum management and parasitic challenge can all affect calf output. Prior to national BVD eradication programme, there was little published information on either prevalence or effect Irish herds. There practices commercial herds have also been few studies liver fluke rumen infection Sixteen farms participating Teagasc/Farmers Journal...
Abstract Although the rumen fluke, Calicophoron daubneyi is now very common and widespread throughout Western Europe, reports of clinical cases are still rare. This study explores epidemiological background to a severe fluke outbreak in 6-month-old heifers on dairy farm Ireland. Sequence analysis cytochrome oxidase subunit 1 (Cox1) gene metacercariae pasture failed identify predominant, possibly pathogenic subtypes. However, estimates metacercarial load indicated that animals were exposed...
Bovine besnoitiosis, caused by the apicomplexan protozoan parasite Besnoitia besnoiti , was diagnosed in an Irish dairy herd. This is first diagnosis of besnoitiosis Ireland or UK and most northerly European outbreak yet described. The occurred following a farm investigation June 2015 into unusual dermatological problem that had been ongoing since 2010. On annual basis, 1–2 per cent cows herd exhibited clinical signs, including skin thickening, alopecia, weight loss poor performance. Others...
With concerns over the development of anthelmintic resistance in cattle nematode populations, we must re-examine our approach to control cattle. Targeted selective treatments (TST), whereby individual animals are treated instead entire groups, being investigated as an alternative. The study objective was determine if usage could be reduced using a TST-based spring-born suckler beef their first and second grazing seasons (SGS) without affecting performance. In season (FGS), 99 calves with...
There have been few studies published internationally which document herd health management practices in suckler beef herds and no Irish studies. The study objective was to status on sixteen over a two year period (2009-2010). farms used the were part of Teagasc BETTER farm programme. mean (s.d.) size, stocking rate size 68 cows (27.6), 2.0 LU/ha (0.3) 64.3 (21.6) adjusted hectares, respectively.

We report on the use of faecal egg count reduction test to evaluate performance ivermectin in treating gastrointestinal nematode infections first grazing season (FGS) calves four dairy farms Co. Kilkenny, Ireland. On each farm, FGS were injected subcutaneously with accordance their live weight (day 0). Calves individually sampled both day 0 and 14. Faecal counts determined using Mini-FLOTAC technique. Composite cultures for farm performed sampling occasion. The reductions (mode) ranged from...
