Abstract

The postpartum period in dairy cows is vital for their health and herd productivity. Effective management, including proper nutrition and disease prevention, helps prevent metabolic and reproductive issues, ensuring optimal milk production and enhancing cow longevity and farm sustainability. The study aims to determine the main postpartum disorders in dairy cows from seven Algerian wilayas: Oran, Tipaza, Mila, M'sila, Setif, Medea, and Ghardaia.. A total of 1153 dairy cows were concerned. Overall, 37.21 % of cows were having 1 postpartum disorder and 25.59% of cows having ≥2 postpartum disorders (p < 0.0001). Inflammatory disorders (31.66%) were more frequent than metabolic disorders (24.89 %) (p < 0.0001). The most frequent postpartum disorders are acute metritis (AM) and lameness (LAM), followed by retained placenta (RP) and mastitis (MAS) (p<0.01). Holstein cows are more prone to mastitis (17.98 %) and delayed uterine involution (6.07%) and Montbeliarde cows exhibit a high prevalence of lameness (52.61 %) (p < 0.001). Inflammatory disorders (metritis, delayed uterine involution) decrease as the number of lactations increases. Lameness is particularly frequent starting from the third lactation (>30%) (p<0.001). Cows that experienced dystocic calving show a higher prevalence of inflammatory and metabolic disorders compared to those with normal calving (p<0.001). Multiparous cows exhibit higher rates of metabolic and inflammatory disorders (p<0.001). Postpartum disorders in dairy cows require careful management to minimize their negative effects on milk production, reproduction, and overall health. Effective monitoring and timely interventions during the early lactation transition period are crucial for maintaining herd performance and profitability.
