Seasonal changes in platform use by adult farmbred silver foxes (Vulpes Vulpes)
Abstract
Seasonal changes in platform use (Wooden U-type platform, area 3090 cm2) were studied during one year in adult farmbred silver foxes (Vulpes vulpes) by daytime scan sampling observations and 24-h video recordings. Platform use was found to be lowest during the coldest part of the year (winter, late autumn) and highest in mid-summer (July). The seasonal pattern in platform use obtained by the scan samplings was in agreement with that obtained by video recordings. Platform use was sex-related being significantly (p < 0.001) higher in females than males. Circadian distribution of platform use was rather similar for both sexes. Hourly use was highest from 4 to 5 a.m. and lowest at about 8-9 a.m. when farm work started. Platforms were mostly used for sleeping and the least for jumping. The animals’ needs for rest, observation and seclusion required by the European Convention were met fairly well by the presently studied platform type. This is demonstrated by of its rather high amount of general use, and because it functioned appropriately as a place for observation and rest. Based on the present data, wooden U-type platforms can be recommended for practical farming purposes, particularly outside the winter period.Downloads
