Genetic improvement of fertility in sheep by selection according to physiological parameters

Abstract: 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 … Show more

“…Success in selection of sheep in regard to their fertility greatly depends on genetic variability of reproductive components (Petrović et al, 1997(Petrović et al, , 2001(Petrović et al, , 2002(Petrović et al, , 2007. Heritability for onset of puberty is low and within the interval of 0,1 to 0,26 (Petrović, 2000).…”
