dc.description.abstractHeredity and correlation of litter size traits were observed in 3693 litters, i.e. in 1622 daughters of two genotypes Swedish Landrace genotype - SL; and F1 ♀ SLxLW. The study included daughters (minimum ten daughters per sire) of 24 sires. Heritability estimates for the total number of piglets per litter in the first, the first two parities, and for all three parities was 0.174; 0.167 and 0.135. Heritability estimates for the number of piglets born alive were 0.181; 0.160 and 0.121, and for the weight of litter at birth 0.166; 0.174 and 0.150. On the other hand, very low heritability was determined for the number of weaned piglets, litter weight of piglets reared, individual weight of born and reared piglets, i.e. for the traits that are under greater influence of the environment (from 0.004 to 0.037). Phenotypic and genetic correlations ranged from weak to complete (rp = 0.021 to rp = 0.973 and rg=0.188 to rg=0.999, respectively). Analysis of the significance of correlations showed that the genetic correlations were statistically highly significant (P (lt) 0.01).en
dc.description.abstractNaslednost i međusobna povezanost osobina veličine legla praćene su za 3693 legla, odnosno kod 1622 kćeri dva genotipa švedski landras - ŠL; i F1 ♀ŠLxVJ. Ispitivanjem su obuhvaćene kćeri (minimalno deset kćeri po ocu) od 24 oca. Heritabiliteti za ukupan broj prasadi u leglu u prvom, prvom i drugom i za sva tri prašenja iznosio je 0,174; 0,167 i 0,135. Za broj živorođene prasadi vrednosi heritabiliteta su iznosile 0,181; 0,160 i 0,121, dok su za masu legla pri rođenju vrednosti 0,166; 0,174 i 0,150. Sa druge strane utvrđen je jako slab heritabilitet za broj odgajene prasadi, masu legla odgajene prasadi, individualnu masu rođene i odgajene prasadi odnosno za ispitivane osobine koje su pod većim uticajem okoline (od 0,004 do 0,037). Fenotipske i genetske korelacije kretale su se od slabih do potpunih (rp=0,021 to rp=0,973 odnosno rg=0,188 to rg=0,999). Testiranje značajnosti korelacija pokazalo je da su genetske bile statistički visoko značajne (P (lt) 0,01).sr
