V.M. Kuznetsov, N.V. Vakhonina
The authors model the closed system of breeding of various size genofond populations. They evaluated the dependence of inbreeding coefficient increase on reproductive age of bulls, duration of their usage, cow’s age during first calving, length of service-period and level of herd’s remount. The expected inbreeding during intensive breeding system was 2 times as great as during extensive system.
Key words: simulation, gene pool conservation, dairy cattle, inbreeding.
