Abstract: Body growth in mammals is an aspect of their biology that has always been interesting and carries important information about the individual’s development. The relationship between growth patterns and factors that are affecting them, such as parasitism, is not entirely clear. In this short communication, we provide information obtained from a young brown bear (Ursus arctos), shot a year after being collared. Analysed growth patterns show a noticeable increase in the weight and circumference of the chest and head. The established low to moderate infestation with Baylisascaris transfuga in relation to absence of other parasites, has not affected the growth processes.

Keywords: body conditions, body mass, body size, brown bear cub
