Viability of Iberian x Meishan F2 newborn pigs. II. Survival analysis up to weaning.

Journal of animal science - 1 Jul 2004

Casellas J, Noguera J L, Varona L, Sánchez A, Arqué M, Piedrafita J

Abstract excerpt

Iberian x Meishan F2 piglet's preweaning survivability was analyzed using categorical data regression procedures within the proportional hazards assumption. A frailty sire model was assumed with the litter effect treated as an additional random source of variation. Moreover, the relative birth weight within litter and the litter effect were considered time-dependent covariates that changed their values in the...
