The Heihe is a Chinese horse breed originating in Heihe City, located on the northern border of Heilongjiang Province along the Amur River. The breed developed in response to the region’s severe continental climate — temperatures drop well below -30°C in winter — and the demand for horses capable of sustained draft and agricultural work under these conditions.
The Heihe is a heavy-boned, cold-blood type horse with a deep chest, muscular hindquarters, and a dense winter coat that provides thermal insulation without the aid of a blanket under normal conditions. Its hooves are adapted to frozen ground and packed snow. The breed is closely related to other northeastern Chinese draft types, including the Heilongkiang, which was developed in the same provincial system through systematic crossbreeding.
Heihe horses are bred for endurance in cold-climate labor: prolonged pulling, farm work over long days, and transport in conditions where lighter breeds would struggle. This hardiness makes the Heihe a practical working animal for the agricultural communities along China’s northern border. The breed is not widely documented in international breed registries, but it occupies a clear ecological and functional niche in the context of Chinese regional horse development. A mare of the breed is expected to produce a foal annually through most of her working life.
