Název v původním jazyce

Stochastic simulation of the influence of insemination on the estimation of breeding value and its reliability

Popis výsledku v původním jazyce

Insemination is used less commonly in the population of beef cattle than in dairy cattle. As a consequence, herds are genetically isolated and their comparison is difficult. The objective of the paper was to evaluace the impact of the use of reference sires in insemination on the estimation of breeding value and its reliability by means of stochastic simulation based on a single addition of calves to the basic set. Simulation was divided into three variants according to the connectedness calves throughsires (variant 1 ? unrelated calves, variant 2 calves related between HYS but unrelated within HYS, variant 3 ? calves related within and between HYS). The degrese of connectedness was determined by computation of genetic drift variance (GDV). The average value of GDV in the basic set was 0.71. In our study the highest values of GDV were reached in simulated variant 3, in which the relationship increased not only between HYS but also within HYS. The lowest values of GDV were in variant 2
