Study of the Main Body Dimensions that are used in the Selection Process in the Reproductive Nucleus of the Nonius Horse from Izvin Studfarm

Abstract

Regarding to a population, the average of phenotypic value is equal with average of genotypic value and that means that the study of average performances in a population has a huge importance. So, the studies of the average values of characters offer us an idea about the population genetic level. This study have the principal purpose to analyse main body dimensions that are used in selection process: withers height, thoracic perimeter and cannon bone perimeter, through the integration of individuals in an evaluation class, in accordance with selection methodology. The biological material is represented by 35 Nonius horses, 4 males and 31 females, at different ages, owned by Izvin Stud Farm, representing the entire reproductive nucleus. The average performances of characters are presented in the paper. We can observe a small level of variability with some differences between sexes. The average performances of the characters are between characteristic limits of the breed.
