Abstract:
In this case study the multifactorial pathogenesis and the various symptoms of the Postpartal Dysgalactia Syndrome was described on a farm. On the day of birth, 35.1 % of sows showed an elevated body temperature of more than 39,5 °C. 78.9 % of all sows had vaginal discharge and 43.9 % of the sows developed a mastitis within the first three days after birth. Overall, in many sows a reduction of more than 4 mm in the thickness of back fat from far-rowing until weaning occurred. Pre- and postpartal energy and protein supply of sows might have therefore not been adequate. In parallell, the feed intake of many sows was disturbed due to different causes. One important factor for inadequate feed intake might have been the inadequate intake of water, which was therefore also a factor for reduction in back fat thick-ness. Inadequate water intake of the sows was identified as one major factor for the devel-opment of PDS as a herd health problem on this farm. Frequencies of specific clinical findings and treatments were related to each other in this study. This one-dimensional analysis was not appropriate to elucidate the relevance of various factors in this complex herd health problem. The analysis of single factors was supplemented by intensive animal observations in this study. On the first day after birth the number of sows with fever was significantly lower, if they had been treated with Oxytocin during birth. Fever was recorded more frequently in sows with a disturbed feed intake on the second day after birth. A simple frequency analysis of disease and production parameters on a farm may support diagnosis of main factors for health problems on farm level. On the farm examined in this study, inadequate flooring with a high risk of skin and claw injuries as well as insufficient water and feed intake were the main factors for the development of PDS.
