Effect of the proportion of Duroc genes in crosses with Large White and Landrace pigs on the characteristics of seasoned Parma ham [Emilia-Romagna]
The aim of this study was to estimate the linear and quadratic effects of the proportion of Duroc genes on traits of seasoned Parma hams by a covariance model. The study was carried out on 167 pigs (87 castrated males, 80 females) from different crosses among Duroc (D), Large White (LW) and Landrace...

Summary: | The aim of this study was to estimate the linear and quadratic effects of the proportion of Duroc genes on traits of seasoned Parma hams by a covariance model. The study was carried out on 167 pigs (87 castrated males, 80 females) from different crosses among Duroc (D), Large White (LW) and Landrace (L) breeds, slaughtered at 300 d of age (LW 170 kg). All pigs were raised under similar conditions. The curing period was 380 days. The proportion of Duroc genes was 0% (LW x L: n. 33), 25% [(LW x (D x L): n. 31 and L x (D x LW): n. 35] and 50% [D x (LW x (LW x L)): n. 68]. The increase in proportion of Duroc genes had a positive linear effect (P0.01) and a negative quadratic effect (P
Sono stati valutati, attraverso l'applicazione di un modello di analisi della covarianza, gli effetti lineari e quadratici dell'aumento della percentuale di geni della razza Duroc sulle caratteristiche dei prosciutti stagionati (durata della stagionatura tipo Parma: 380 giorni), provenienti da 167 suini (87 maschi castrati, 80 femmine), appartenenti a diversi incroci, alla cui formazione hanno partecipato le razze Duroc (D), Large White (LW) e Landrace (L), macellati a circa 300 d di età (PV 170 kg). La quota di geni della razza Duroc è risultata pari a 0% (LW x L: n. 33), a 25% [(LW x (D x L): n. 31 e L x (D x LW): n. 35)] e a 50% [D x (LW x (LW x L)): n. 68]. L'aumento della proporzione di geni Duroc porta a un aumento lineare (P0,01) e a una riduzione quadratica (P |
