Occurrence of Larvae in Male Roe Deer ( L.) in The Lublin Upland, Poland, and Their Impact on Particular Animal Health Indicators.

INTRODUCTION

The aim of the study was to carry out epizootic assessment of male roe deer to detect the presence of larvae and determine the influence of the parasite on the carcass and antler weight in animals living in different habitats.

MATERIAL AND METHODS

The investigations were based on post-mortem analysis of infestations of the nasal passages and throat of 177 male roe deer culled between May 11 and September 30, 2020 in hunting districts of the Lublin region in Poland. The individual quality of the animals was assessed by weighing the gutted carcasses after cooling, and the antlers were weighed after dissection and their total weight was determined.

RESULTS

The parasite prevalence ranged from18 to 48% according to habitat type, with a mean value of 33%. The highest prevalence was detected in bucks living in grassland ecosystems. The presence of the parasites exerted influence on the individual condition of the animals, which was reflected in reduced carcass and antler weight. The differences were found both in young individuals and in somatically fully developed animals, but they were not statistically significant in all age groups.

CONCLUSION

Although the parasitic infestations impaired the individual condition traits, their parametric values in most cases were not lower than those reported from other regions of Poland. Despite the infestation, male roe deer from the Lublin region are characterised by high carcass and antler weight.
