Abstract

The objective of this study was to obtain fundamental information on the development of the effective methods for preventing invasions into a fattening cattle barn by wild boar(Sus vittatus leucomystax). We investigated the effect of wolf (Canis lupus) urine as a repellent on wild boar. Three treatments were assigned at the entrance of trap space (6.Om2) :1) no plastic bottle and no wolf urine (control), 2) plastic bottle without the urine (treatment 1) and 3) plastic bottle containing the urine (treatment 2). The number of access to the entrance was 70, 50 and 67 heads per day for the control, treatments 1 and 2, respectively. Wild boars were very cautious against plastic bottle immediately after treatment 1, and they exhibited exploratory behavior using snout. However, there were no differences in the time of access to the entrance among 3 treatments. In contrast, wild boars did not avoid wolf urine in the treatment 2. The results indicated that wolf urine had no effect on the prevention of wild boar invasion.
