Umbilical hernias were classified bysize. Scrotal hernias and kyphosis were not subclassified.Descriptive statistics were performed for prevalence of defects.Prevalence, gender, and mortality in affected and non-affected pigswere compared using chi-squared tests. Gain in the first 80 dayswas compared by ANOVA in pigs with umbilical hernias of varioussizes. Prevalence and mortality rate for umbilical hernias did notdiffer by gender (P > .05), but kyphosis occurred morefrequently in barrows (P < .05). Mortality rates werehigher among affected pigs, but did not increase withumbilical-hernia score (P = .30). Pigs that died spentconsiderable time in the finisher, with probable compromise oftheir welfare during this time. Welfare and economic considerationsmay make euthanasia preferable to placing pigs with hernias orkyphosis in the finisher. ER -
