Analysis of intravital assessment results in purebred and crossbred boars
1879 purebred boars: Duroc (D), Hampshire (H) and Pietrain (Pn) as well as their two-crossbreds (D x H, H x D, Pn x H, H x Pn, Pn x D, D x Pn) were analysed after a living assessment completed between 1995–1998 within the area of activity of the Animal Breeding Station in Olsztyn.

| description | 1879 purebred boars: Duroc (D), Hampshire (H) and Pietrain (Pn) as well as their two-crossbreds (D x H, H x D, Pn x H, H x Pn, Pn x D, D x Pn) were analysed after a living assessment completed between 1995–1998 within the area of activity of the Animal Breeding Station in Olsztyn. The standardi- zed daily gains in body weight ranged between 594 g (H) and 628 g (Pn x D). The thinnest backfat layer was observed in Pietrain boars and their crossbred boars. The height of loin eye was the best for boars Pn and for all crossbred animals. The lean content in the body of the assessed boars ranged from 56.2% (H) to 60.0% (Pn). The highest value of selection index was found for Pn boars (124 points) and crossbred boars Pn x D and Pn x H, the lowest index value was observed for purebred H boars (109 points). The correlation coefficient between the index and daily gains range from 0.69 (P ≤ 0.01) (H) to 0.91 (P ≤ 0.01) (H x D), between the index and the height of loin eye range from 0.57 (P ≤ 0.01) (H) to 0.75 (P ≤ 0.01) (Pn) and between the index and the lean content range from 0.13 (P ≤ 0.05) (H) to 0.71 (P ≤ 0.01) (Pn). |
