Abstract
In cattle breeding enterprises of the Vladimir region, regardless of the intensity of production and
keeping technologies, cows exhibit violations of the reproductive cycle associated with an imbalance
in mineral metabolism.
Highly productive cows have rather low rates of commercial offspring, and the service period
exceeded the general norm for Holsteinized black-and-white cattle. At the same time, the specific
gravity of soils with an insufficient content for most agricultural forage crops for cattle in terms of
cobalt – 95,8%, zinc – 81,9%, manganese – 63,8%, copper – 52,9% of the total arable area land.
The performed gynecological clinical examination of lactating cows using mammological examinations
and taking into account the geoprovincial characteristics of the Vladimir region, makes it
possible to determine the nature of the prevailing pathology, to establish its main causes, and to
present specific proposals for carrying out preventive and therapeutic measures based on the real
capabilities of farms.
