The aim of the present study was to identify nutritional risk factors for the occurrence of displaced abomasum (DA) in Holstein dairy cattle raised in regions with highly variable nutritional management. Feeding program data were collected from 30 dairy farms throughout Kosovo via use of a standardized questionnaire, and an AgriNIRTM Analyser was used to analyze the nutrient composition of forage (hay, corn silage) fed to cattle on those farms. A diagnosis of DA was made via auscultation/percutation in the area of the last rib and hearing of a ping sound. Multivariate linear regression models were used to determine risk factors associated with the incidence of DA. The overall incidence of DA in this study was 4.9% (38 cases among 769 cows). Of cows diagnosed with DA, 81.6% (31/38) had left side DA and 18.4% (7/38) had right side DA. Nearly all DA occurred during the first month of the postpartum period 92.1% (35/38); only 7.9% (3/38) were observed in the pre-partum period. Risk factors that elevated the occurrence of DA included increased intake of concentrate feed after parturition (P<0.002), increased body condition score at calving (P<0.01), larger herd size (P<0.021), and increased daily consumption of corn silage in the pre-partum transition period (P<0.051). An increase in daily consumption of grass hay in the pre-partum transition period decreased (P<0.014) the incidence of DA. The results of this study are useful for developing enhanced nutritional management protocols to reduce the incidence of DA in Holstein dairy cattle.
