Sažetak
Direktni i indirektni efekti pojedinih varijabli (dužina tela (BL), visina krsta (RH), dužina krsta (RL), širina krsta (RV), širina plećke (SV), visina grebena (WH), obim grudi (HG) i dužina slabine (FL) uticaj na živu mase na rođenju i odlučenju nigerijske autohtone rase svinja, u polu intenzivnom sistemu držanja, su ispitivani pomoću analize pravca/puta. Rezultati analize ukazuju da je koeficijent korelacije između telesne težine i dužine tela pri rođenju najviši (0,59), dok je na odbijanja, širina krsta imala najveći koeficijent korelacije sa telesnom težinom (0,60). Odnosi su bili od niskog do visokog. Direktan efekat linearnih osobina na telesnu težinu na rođenju su bili najviši sa visiniom grebena i dužinom slabine, slično tome, obim grudi i dužina krsta imali su bolji direktan uticaj na telesnu težinu na odlučenju od drugih linearnih osobina. Rezultati pokazuju da postoji varijabilnost u odnosu između telesne težine i linearnih osobina sa uzrastom, slično tome, razvoj tkiva i kostiju igra značajnu ulogu u određivanju težine u autohtonih svinja. Tako selekcija na povećanje težine u odrasloj fazi grla se može bolje postići pri odbijanju, pružajući pravac za selekciju na povećanje težine u autohtonih svinja.
