Description

In this study, we selected Khovd, Arkhangai, Dornod, and Umunugobi provinces respectively in 4 pastoral districts of Mongolia for carrying out the following analysis. The regional characteristics of livestock damage caused by variations in weather conditions were clarified by analyzing the relationship between the meteorological factors and mortality of sheep which was major livestock in the whole county. This analysis showed the following results: 1. Livestock was damaged by the heavy snowfall in winter in all provinces. 2. In Umunugobi province of the highest-temperature and the most drying area, many sheep starved to death in winter when the growth of pasture was degraded by high temperature and low rainfall in summer, and its mortality also increased by cold rainfall in spring and autumn seasons. 3. It caused livestock damage that the drinking water in winter was insufficient by a decrease in snowfall of March in Umunugobi and Khovd provinces with less precipitation. 4. In Arkhangai province with the lowest temperature, livestock was damaged by low temperature in winter. 5. In Dornod province, the livestock was damaged by long-term blizzard in April.
