The incidence of abnormal limb development in the Irish thoroughbred from birth to 18 months.

摘要: Summary A two part survey was carried out in Irish Thoroughbred horses 1988 and 1989 to establish the incidence prevalence of developmental skeletal problems, particularly possible manifestations orthopaedic disease (DOD). Survey One a retrospective study based on questionnaire involving foal crops 46 stud farms for 3 successive seasons; 1711 animals initially documented represented 10.46% registrations. The second involved repeated monitoring crop from birth 18 months age 17 farms. 248 foals examined 4.24% Treatment DOD deemed necessary 11.3% One. Angular limb deformities physeal dysplasia (“epiphysitis”) together constituted 72.9% cases treated. peak problems occurred between weaning end December. More than half treated (53.9%) recovered completely, ie achieved expected sale value as yearlings, 27.5% those showed incomplete recovery mild moderate loss remaining 18.7% were killed or lost much their value. In survey, while 67% exhibited some form DOD, severity not significantly different Again, angular deformity predominant clinical conditions greatest during early winter. During suckling phase colts had greater DOD. At all other stages similar both sexes. However, severely affected categories more fillies killed. There significant differences amongst
