Abstract: (3379 Views)
In this research, the pedigree of 2164 Turkmen horses born in 1970 to 2016 were used to estimate the pedigree completeness level, inbreeding coefficients and mean average relatedness of livestock. The average equivalent complete generation, as a measure of pedigree completeness level, estimated as 0.49. In order to predict the incidence of inbreeding in the future generations, the average correlation coefficient between live animals was estimated. The average relatedness of the population was estimated to be 0.52%. 0.5 percent of the total registered horses were inbred. Mean, minimum and maximum of inbreeding coefficients were 0.06 , 0 and 0.25 percent for whole animals, respectively. Also mean, minimum and maximum inbreeding coefficients for inbred animals were 0.125, 0.03125 and 0.25 percent, respectively. Low average coefficient of inbreeding in this study showed that the severity of kinship is low, but with the necessary genetic control at the time of mating, it is possible to prevent high inbreeding in some individuals.
