| gross margin losses due to salmonella dublin infection in danish dairy cattle herds estimated by simulation modelling. | salmonella dublin affects production and animal health in cattle herds. the objective of this study was to quantify the gross margin (gm) losses following introduction and spread of s. dublin within dairy herds. the gm losses were estimated using an age-structured stochastic, mechanistic and dynamic simulation model. the model incorporated six age groups (neonatal, pre-weaned calves, weaned calves, growing heifers, breeding heifers and cows) and five infection stages (susceptible, acutely infect ... | 2013 | 23628337 |
