Why was animal husbandry only of secondary importance in the economy of the Russian peasant? What difficulties did the natural conditions create for the peasant for raising livestock?

In most cases, the peasant simply did not have anything to buy a large number of animals for, so they were engaged in agriculture. The cattle, in this case, were harnessed to the plow. Thus, animals were used as an auxiliary tool, not food. You can put the grain in the barn and forget about it, and the animals ask for food every day. People gave birth to few animals, since their maintenance took a lot of time and money, especially during the winter periods. In a harsh winter, all the livestock could die and the peasant would be left with nothing.
