| Abstrakt: | Puerperal diseases are major postpartum complications in dairy cattle and may compromise both survival and production performance. This study evaluated how specific puerperal diseases influence early culling risk and standardised 305-day milk traits in Slovak Spotted cows. A total of 792 animals were clinically assessed during early postpartum and classified as healthy or affected by ketosis, metritis, retained foetal membranes, parturient paresis, or by comorbid diseases, defined as the concurrent occurrence of two or more disorders. Logistic regression models indicated that ketosis was associated with the highest odds of culling compared with healthy cows (odds ratio = 2.23; P = 0.05). The multivariable model had a predictive discrimination of 0.75, as indicated by the area under the receiver operating characteristic curve, suggesting moderate performance. After excluding the cows culled during the puerperium to avoid bias from incomplete lactation data, the dataset was restricted to 546 animals. Within this group, metritis was associated with the lowest 305-day milk yield, with an average decrease of 1 124 kg compared with healthy cows (P < 0.05). Protein content was slightly lower in cows affected by puerperal disease (P < 0.05), with no significant differences in milk yield, fat or lactose content, nor lactation persistency index. Parity and sire line still remained the primary determinants of variation in milk traits. The results can be used to support decision-making in herd health management and genetic improvement strategies aimed at enhancing cow longevity and production efficiency. [ABSTRACT FROM AUTHOR] |
