Dairy efficiency of the sheep planted in Republic Tatarstan

On sheep of a different direction and the breeds planted in Republic Tatarstan, are studied quantitative and quality indicators of dairy efficiency. The established interpedigree distinctions in fiber and fat level in milk have appeared less considerable, than intrapedigree variability of these signs. The greatest variability characterises a single yield of milk that creates preconditions for selection and the forecast of precocity of young growth at early stages of development.
