seroprevalence of equine herpesvirus 1 in mares and foals on a large hunter valley Stud Farm in years pre and postvaccination
Australian Veterinary Journal, 2003Co-Authors: C E Foote, James R. Gilkerson, James Millar Whalley, D N LoveAbstract:Objective To examine the prevalence of equine herpesvirus 1 antibody in mares and foals on a large Hunter Valley Thoroughbred Stud Farm in New South Wales before and after the introduction of an inactivated whole virus vaccine. Design Cross-sectional serological surveys performed in February 1995 and 2000 to determine the prevalence of EHV-1 antibody-positive mares and foals. A further cross-sectional survey was carried out in 2001 to complement the 2000 data. Study population Two hundred and twenty-nine mares and their foals were sampled in 1995 and 236 mares and their foals were sampled in 2000. The Study population comprised all of the mares with foals at foot on this property at each sample period. Fifty mares were sampled in both Studies. A further 264 mares and their foals were sampled in 2001. Procedure A blood sample was collected from each mare and foal at the beginning of February 1995, 2000 and 2001. Each sample was tested in triplicate using an antibody-detection ELISA that is type-specific for EHV-1 and EHV-4 antibodies. Results The prevalence of EHV-1 antibody-positive mares was not statistically different in 2000 compared to 1995. However, the prevalence of antibody-positive foals was significantly lower in 2000 than in 1995. In 2001, the prevalence of antibody-positive mares was higher than in 2000, but not different from that in 1995. The prevalence of antibody-positive foals in 2001 was not significantly different from the prevalence observed in 1995 or that observed in 2000. However, when the three Studies were compared there was a significant variation in the prevalence of EHV-1 positive foals due to the variation between the 1995 and the 2000 data. Conclusions Mares are the source of virus from which foals are infected early in life and following analysis of the 2001 data, the difference in the prevalence of EHV-1 antibody-positive foals between 1995 and 2000 was likely to be a reflection of seasonal, nutritional and management factors, rather than the result of vaccination.

serological responses of mares and weanlings following vaccination with an inactivated whole virus equine herpesvirus 1 and equine herpesvirus 4 vaccine
Veterinary Microbiology, 2002Co-Authors: C E Foote, D N Love, James R. Gilkerson, J M WhalleyAbstract:Equine herpesvirus 1 (EHV-1) is a major cause of respiratory disease and abortion in horses worldwide. Although some vaccines have been shown experimentally to reduce disease, there are few reports of the responses to vaccination in the field. This Study measured antibody responses to vaccination of 159 mares (aged 4-17 years) and 101 foals (aged 3-6 months) on a large Stud Farm with a killed whole virus EHV-1/4 vaccine used as per the manufacturer's recommendations. Using an EHV glycoprotein D (gD)-specific ELISA and a type-specific glycoprotein G (gG) ELISA, respectively 13.8 and 28.9% of mares, and 42.6 and 46.6% of foals were classed as responding to vaccination. Additionally, 16.4 and 17.6% of mares were classified as persistently seropositive mares. Using both assays, responder mares and foals had lower week 0 mean ELISA absorbances than non-responder mares and foals. Responder mares were ten times more likely to have responder foals, and non-responder mares were six times more likely to have non-responder foals than other mares using the gG ELISA. Mares aged 7 years or less and foals aged 4 months or more were more likely to respond to vaccination than animals in other age groups. There was no association between response of mares and the number of previous vaccinations received and persistently seropositive mares did not respond to vaccination. This Study documents the responses of mares and foals to vaccination in a large scale commercial environment in 2000, and suggests that knowledge of antibody status may allow a more selective vaccination strategy, representing considerable savings to industry.

epidemiology of ehv 1 and ehv 4 in the mare and foal populations on a hunter valley Stud Farm are mares the source of ehv 1 for unweaned foals
Veterinary Microbiology, 1999Co-Authors: James R. Gilkerson, J M Whalley, Heidi E Drummer, M J Studdert, D N LoveAbstract:The prevalence of EHV-1 and EHV-4 antibody-positive horses was determined using a type specific ELISA on serum samples collected from 229 mares and their foals resident on a large Thoroughbred Stud Farm in the Hunter Valley of New South Wales in February 1995. More than 99% of all mares and foals tested were EHV-4 antibody positive, while the prevalence of EHV-1 antibody positive mares and foals were 26.2 and 11.4%, respectively. Examination of the ELISA absorbance data for the individual mares and foals suggested that the EHV-1 antibody positive foals had been infected recently with EHV-1 and that a sub-group of the mare population was the likely source of infectious virus for the unweaned foals.

Imperial Court Stud Farm Kladruby nad Labem during the Rudolph II's Era
2021Co-Authors: Petričáková ŠtěpánkaAbstract:The bachelor thesis analyses horse-breeding during the reign of Rudolph II. (1576- 1612) in the horse park in Kladruby and Labem. The thesis is is divided into three thematic parts. The first part deals with noble renaissance breeds of horses in Europe, their training and care of them. The second part is devoted to the tradition of horse-breeding in Kladruby and Labem. The main topic of this thesis is the research of the Stud Farm in Kladruby n. L. in the Rudolph's II. era, its description, function and organizational structure. In the last part there is a place for describing the relationship of Rudolf II. to horses. The aim of this thesis is to describe Rudolf II.'s reasons for promoting the Stud Farm Kladruby nad Labem into the imperial court Stud Farm and define the consequences of this act.

Práce je rozdělena do tří tematických celků. První část se zabývá ušlechtilými renesančními plemeny koní v evropském prostoru, jejich výcvikem a péčí o ně. Druhá část je věnována tradici chovu koní v Kladrubech nad Labem. Hlavním tématem této práce je výzkum hřebčína v Kladrubech n. L. v rudolfínské době, jeho popis, funkce a organizační struktura. Poslední část je zaměřena na vymezení vztahu Rudolfa II. ke koním. Cílem této práce je vystihnout důvody vedoucí k povýšení hřebčína v Kladrubech n.
