Significance of Genetic and Environmental Factors in Realization of the Hereditary Potential of Record-Holding Cows' Longevity

Mozhilevsky P. L.

 




A positive correlation is found between the level of record productivity of record-holding cows and duration of their farm use. A positive correlation is found to exist between the value of the record milk-yield and repetition of milk-yields similar to the record. It is stated that the overwhelming majority of record-holding cows are well developed, have solid sound constitution, better adaptability to living conditions, higher viability.
