Abstract
Our primary interest is in welfare of Amur tiger (Panthera tigris altaica, Temminck, 1844) in the Barnaul Zoo and Leningrad Zoo. As discussed below, behavioral researches can reveal much about the welfare of captive wild animals. Amur tiger s behavior is studied and time budget is calculated for males and females. The Schorygin’ similarity coefficient of behavior is determined (82.64% and 86.76%). We analyzed the differences in their behavior before and after olfactory enrichment. Cinnamon oil reduces pacing, sheltering, sleep and rest time, play behavior, increases exploratory behavior in 50% of researched Amur tigers. The reaction time of the flemen increased in both males. Younger animals better perceived olfactory enrichment. Stereotypical behavior (pacing) have decreased in post-enrichment day.
Highlights
The species diversity of the planet decreases every year; the habitat of animals is changing, the number of potential species of prey for large cats is decreasing
We studied the behavior of the male (Amadei was 9 years old) and female (Gerda was 16 years old) tigers in the «Leningrad Zoo» (Saint Petersburg) from 25 January to 5 February 2016 and in September 2016
In order to assess the well-being of the animal it is important to quantitate the time' budget and to analyze the causes of such pathological behaviors such as movement stereotypes, abnormal immobility, long-term stay in the shelter and others (Table 1)
Summary
The species diversity of the planet decreases every year; the habitat of animals is changing, the number of potential species of prey for large cats is decreasing. Part of the role of conservation of species diversity can take on specialized nurseries and zoos. The Amur tiger (Panthera tigris altaica, Temminck, 1844) is one of such species. Common animal welfare problems, which occur with captive animals, include low behavioral diversity, abnormal behavior and excessive inactivity (Mason et al, 2014; Yu et al, 2009). Sensory enrichment is one of the factors of an animal welfare that seeks to enhance the quality of captive felids care by identifying and providing the environmental stimuli necessary for optimal psychological and physiological well-being. Olfactory enrichment is a common approach for addressing stereotypic behavior in captivity animals. The purpose of the investigation is to establish special aspects of the behavior of the Amur Tiger (Panthera tigris altaica, Linnaeus, 1758) and sensory enrichment with cinnamon oil (Cinnamomum zeylanicum, Blume)
