Abstract: The aim of this study was to determine risk factors associated with milk fever (MF) occurrence in Costa Rican grazing dairy cattle. A total of 69,870 cows from 126 dairy herds were included in the study. Data were collected in the Veterinary Automated Management and Production Control Program software by the Population Medicine Research Program of the Veterinary Medicine School, National University of Costa Rica, from 1985 to 2014. To determine the risk factors for MF, 2 logistic regression mixed models were e… Show more

“…This effect was determined to be highly significant according to LA and TA models (Table 2). Predicted incidences for MF according to parity, obtained from LA and TA model showed a clear increasing pattern from parity 1 to 6 ( Figure 1); these results are also consistent with previous studies (Horst et al, 1997;Lean et al, 2006;Roche and Berry 2006;Reinhardt et al, 2011;Saborío-Montero et al, 2017). Several reasons have been suggested for this effect, such as lower capacity to move calcium from bone in older cows, along with the reduction in transport of intestinal calcium and decrease in production of 1,25-(OH) 2 D 3 , or the increased colostrum yield in these animals.…”

“…Observed incidence of MF was higher in Jersey than in Holstein, intermediate for F 1 , and lowest for 3/4H 1/4J cows. Previous studies have shown greater susceptibility to MF in the Jersey breed compared with the Holstein breed, whereas Holstein × Jersey crossbred cows have shown intermediate risk to suffering the disease (Lean et al, 2006;Roche and Berry, 2006;Saborío-Montero et al, 2017).…”

“…El número de parto es el factor de riesgo que tiene mayor efecto sobre la incidencia de hipocalcemia clínica, en donde un animal de 3 y 6 o más partos tiene respectivamente 11,8 (IC 95% 9,12-15,27) y 52,4 (IC 95% 40,94-67,08) veces la probabilidad de sufrir fiebre de leche, en comparación con un animal de primer parto (Saborío-Montero et al 2015). Esto coincide con los hallazgos de Sánchez y Saborío-Montero (2014a, 2014b) quienes encontraron, en vacas estudiadas en varias fincas de la zona de Cartago, Costa Rica, un patrón similar en cuanto al aumento de la incidencia de fiebre de leche conforme avanzaba el número de lactancia.…”

“…Therefore, it is not surprising that these are also the health events more frequently reported in the VAMPP® database ( Figure 5). The VAMPP® database has been used successfully to investigate environmental and genetic factors that affect important health problems, like mastitis (Mora et al, 2015;, lameness (Solano-López et al, 2018) or milk fever (Saborío-Montero et al, 2017;.…”
