Genetic improvement of fertility in sheep by selection according to physiological parameters
Genetsko poboljšanje plodnosti ovaca selekcijom po fiziološkim kvantitativnim parametrima
Abstract
In this paper, fertility parameters of sheep are discussed and principles analyzed in order to obtain the optimal methods for their evaluation. Mathematical procedures for evaluation of genetic and phenotypic parameters and anticipation of genetic values, today, are mainly based on different linear and non-linear concepts, therefore it is necessary to accept the reality that there is no absolute accuracy. Special emphasis is on the possibility of use of physiological quantitative fertility indicators in sheep selection, considering that there is correlation between them and fertility traits. In this regard, the degree of response to direct and indirect selection within population is analyzed in order to established the nature of parameters necessary for evaluation of data and determine the relative degree of such response.
U radu se razmatraju parametri plodnosti ovaca i analiziraju principi iznalaženja optimalnih metoda za njihovu procenu. Ističe se da su matematički postupci za procenu genetskih i fenotipskih parametara i predviđanje genetskih vrednosti danas uglavnom zasnovani na različitim linearnim i ne linearnim konceptima, pa je zbog toga potrebno prihvatiti realnost da potpuna tačnost za sada ne postoji. Poseban akcenat se stavlja na mogućnost korišćenja fizioloških kvantitativnih pokazatelja u selekciji ovaca na plodnost, s obzirom da postoji korelacija između njih i osobina plodnosti. U tom smislu, analizira se stepen odgovora na direktnu i indirektnu selekciju unutar populacije, kako bi se ustanovila priroda parametara neophodnih za ocenu podataka i utvrdili relativni stepeni takvog odgovora.
