Popis: Dystocia in sheep is usually managed by foetal delivery vaginally (VD), or caesarean section (CS). The aim of this study was to develop clinical prognostic models using the presenting features of ewes. During the 2013–2014 lambing season, a prospective cohort study of all ewes (n = 429) and lambs (n = 700) presented to a UK practice was performed. Logistic regression methods were employed to investigate associations between presenting details of the ewe and the outcomes: immediate survival of ewes and lambs, and seven-day survival. For the VD group, at presentation 203 ewes survived (94.0 %); and of the 164 available for follow-up, 155 survived, representing 87.6 % of those initially presented where follow-up was possible. At presentation 211 lambs survived (56.9 %); and of the 162 available for follow-up, 144 survived, representing 44.7 % of those born. For the CS group, at presentation, 205 ewes (99.0 %) survived; and of the 174 available for follow-up, 157 survived, representing 89.2 % of those initially presented, where follow-up was possible. At presentation 247 lambs (77.7 %) survived; and of the 215 available for follow-up, 179 survived, representing 62.6 % of those born. Ewes and lambs have similar/improved chances of survival in first opinion practice compared to hospitalised populations.
