Petr is a senior herdsman at the Aduch farm. He has been working on his farm for ten years. His father was also a herdsman, and Petr looked after cows when he was a child. In his farm Petr keeps cattle of Kalmyk breed which, he says, are cold-resilient, healthy, not afraid of wolves, and do not run away from their pastureland. Kalmyk cows have red skin, round-shaped curved horns, and delicious meat. Grown-up cows may weigh up to 700 kilograms, and bulls up to a ton. His cows graze in pasture all year around, and calves spend the first five months with their mothers. After that they are separated.
