The Kholmogory breed of cows is the oldest domestic dairy breed. When it was withdrawn, emphasis was placed on the volume of milk received, as well as an increase in its fat content.
It is believed that the appearance of the Kholmogory breed originates in the seventeenth century. Literary sources mention the Dvina district, located on the territory of the present Arkhangelsk region. There, in the north of the Russian state, animal husbandry was actively developing in the first half of the sixteenth century.
Arkhangelsk was one of the major commercial ports of the country, which also participated in international trade. Through it there was an active trade in meat, milk, and also live cattle. It’s significant contributed to the development of animal husbandry in the region. The floodplain of the Northern Dvina River was rich in water meadows, and cattle were grazing on them. In winter, cows received hay in abundance. At that time, the color of local cattle was divided into three colors:
- Кара жана ак.
At the beginning of the eighteenth century, black-and-white cattle were brought from Holland. It was supposed to be crossed with the Kholmogory breed, but this did not have a significant effect on the characteristics of the animals. Mid-eighteenth to late nineteenth centuries livestock from Holland was again imported to this region, among which there were more than fifty bulls.
Another attempt to change the characteristics of the breed was made already in the twentieth century. From 1936 to 1937, in some farms, they tried to cross the Kholmogory breed of cows with the Ostfriz. The purpose of crossing was to increase milk production and improve the exterior. However, this attempt failed due to a decrease in the fat content of milk.
In the eighties, to correct distinctive features, bulls of the Holstein breed were used, whose homeland is again Holland. At the same time, intrabreed types were bred for various regions of the country:
- Central – for the central part of Russia;
- Northern – for the Arkhangelsk region;
- Pechorsky – for the Komi Republic.
At the beginning of 1985, there were over 2,2 million heads in the country. At the beginning of 1999, the number of Kholmogory heads increased to almost 2,4 million. As a result, the Kholmogory breed accounted for 8,7% of the total number of dairy cattle in the country. These quantitative characteristics allowed the breed to take fourth place among others in terms of livestock numbers.
The Kholmogory breed of cows was used to breed Istobenskaya and Tagilskaya.
