Description
All health-related events and treatment costs were recorded through fortnightly interviews with the herdsmen of 104 Simmental dairy farms in Upper Bavaria, Germany, from autumn 1987 to spring 1990. The data include 8381 calvings. For 10 different disease classes (dystocia, parturient paresis, retained placenta, metritis, fertility problems, mastitis, udder problems, claw disorders, leg disorders, and other diseases) the sum of all treatment costs from calving up to either the subsequent calving or up to culling were computed. A multiplicative model with 3 covariates (farm, parity, and type of end of lactation (culling or subsequent calving)) was fitted to these observations. Farm effects were significant for almost all diseases. The average sum of treatment costs per calving with an associated disease was estimated as the average expected value for this sum, where averaging is over the farms. These costs ranged from 29 DM (claw disorders) up to 137 DM (dystocia). The average costs per calving (with or without disease) ranged from 1.59 DM (injuries of the udder) to 10.90 DM (fertility problems). Corresponding costs per cow and year were 1.74 DM and 12.24 DM, respectively
