..The study provided evidence for S. zooepidemicus and S. pneumoniae playing an important etiological role in the pathogenesis of IAD in young horses...

..Offspring hip score could be reduced substantially by using only parents with zero hip score...

..Insight, even for these complex diseases, can be derived from further detailed statistical evaluation of datasets such as those described in this paper...

..The models reported here provide quantitative predictions of likely health benefits from selective breeding...

..The breeders in UK tended to use healthy sires for breeding but they have taken less care in selecting dams. Our regression models emphasise the need for both sires and dams, particularly dams, to be healthy with very small hip scores...

....

..If so, glaucoma can be controlled by breeding only from sires and dams with a minimum degree of goniodysgenesis...

..quot; In 2-year-olds and following two doses of vaccine in yearlings, there was no significant relationship between these factors and SRH titre...

..7%...

..The use of the sub-unit vaccine in combination with a differential diagnostic test based on other EAV antigens would enable serological discrimination between naturally infected and vaccinated equines...

..These data provide the first direct evidence that cardiac size influences athletic performance in a group of mammalian running athletes...

..POTENTIAL RELEVANCE: Knowledge of significant risk factors should allow formulation of practical measures, such as track watering, to reduce the risks of EIPH and epistaxis in racehorses...

....

..Trainer was associated with differences in stress fracture risk after adjusting for exercise distances and surface but age and gender were not...

..Potential relevance: This study lays the basis for further studies of the facets involved in wastage...

....

..Emphasis is placed on the need for clearly stated hypotheses and the consideration of equivalence, rather than significance testing when considering safety studies...

..zooepidemicus types. Novel S. zooepidemicus types were identified, including previously untyped HV regions and intra-strain multiples of both the HV region and intergenic spacer types...

..The method requires validation in the field...

..Cats are commonly anaesthetized in veterinary practice, but recent figures describing the frequency of or risk factors for anaesthetic-related death are not available. The aims of this study were to address these deficiencies...

..Cardiac murmurs associated with valvular regurgitation occur commonly in conditioned performance horses, but their association with athletic performance is unknown...

..5% and may actually decrease it by as much as 5%. This general approach should be used in all field studies of vaccine safety...

....

..We develop a modified model that incorporates some heterogeneity in levels of infectivity, and compare this with the simpler model...

..Trainer and jockey contributed very little to the variation in the risk of falling...

..The mean hip score of the dogs was positively and significantly correlated with their age. If this relationship with age is ignored, various offspring/parental relationships and the estimates of heritability are likely to be distorted...

..Enlarging the model by including its age when examined made it possible to quantify the significant genetic parental effects and the effects of the animal's month of birth and its age when examined...

..3 and 77.1% (D. pteronyssinus 19.3% and D. farinae 67.9%) and the specificities varied between 64.2 and 96.6% (D. pteronyssinus 96.6% and D. farinae 89.3%)...

..Model results show that this practical alternative would offer a significant increase in protection. Spread of infection between yards is also considered to ascertain the risk of secondary outbreaks...

..Equine influenza was significantly associated with clinical respiratory disease but it was a very rare infection in this well-vaccinated population, only occurring in three cases...

..Identification and use of the safest anaesthetic drugs should support this aim. Experimental evidence has suggested that isoflurane should be a safer maintenance agent in equine anaesthesia than halothane...

....

..POTENTIAL RELEVANCE: Studying injuries in racehorses in training can provide a scientific basis for the design of safer training regimes...

..These data are unique and provide a valuable basis for future research into the aetiology and epidemiology of canine tumours...

..POTENTIAL RELEVANCE: Gender differences in bone cell activity in 2-year-old colts and fillies may influence bone's adaptive responses to training and risk of injury...

..The results were sensitive to the prevalence of the infection, but when it was low, there appeared to be few benefits in continuing to culture cervical swabs routinely. However, such swabs are vital when the disease is suspected...
