Abstract

In order to study the effect of incomplete sire's pedigree on GENETIC TREND (bBv,y) and gain (R)of quantitative trait, two population were simulated with the heritability 0.15 and 0.30. For eachpopulation, information resulted from ten years of selection were saved in different files. Ingenerated data files, the sire numbers were eliminated from pedigree file with 0, 10, 20, …, 100percentage by two randomly and sequentially methods. The data files were analyzed usinganimal model. In two populations and the sire numbers deletion method, GENETIC TREND weresignificantly reduced with increasing the sire number deletion proportions. Reduction ofestimated GENETIC TRENDs in no sire numbers data file rather than complete pedigree's andsimulated base population, were 86.18% and 89.1% in population 1 and 88.42% and 90.16% inpopulation 2 respectively. Reduction of bBv,y and R in lower deletion proportions were higherthan the later one in random deletion method while were uniformly in the sequential deletionmethod. Annually GENETIC GAINs were significantly decreased based on growing sire missingproportions. Then, it is necessary for breeders to increase accuracy of sire numbers recording inbreeding flocks.
