Genetic trends in maternal and neonatal behaviors and their association with perinatal survival in French Large White swine

Abstract: Genetic trends in maternal abilities were studied in French Large White sows. Two lines representing old-type and modern-type pigs were obtained by inseminating modern sows with semen from boars born in 1977 or 1998. Successive generations were produced by inter-se mating. The maternal performance of sows from the second generation was compared in farrowing crates. Video analysis was performed for the 1st h after the onset of 43 and 36 farrowing events, and for the 6 first hours for 23 and 21 events, in old-ty… Show more

“…There is a growing awareness of consumers and of the general public towards animal welfare, and the current European legislation includes several measures to minimize animal stress in the production farms and also during transportation and at the slaughterhouse. The behavior of the domestic swine has been actively investigated considering maternal-neonatal interactions [ 5 ], disease [ 6 ], feeding [ 7 ], aggression and affiliation during social conflict [ 8 ], and during group housing [ 9 ]. However, identification of the associative areas of this species and the functional wiring of the relative circuitry is still poorly understood.…”

“…In this line, several approaches have been implemented over the last 40 years in order to select animals for production traits. A number of studies have reported that highly selected livestock are more at risk for behavioural, physiological, and immunological problems and respond worse to stressors [30][31][32].…”

“…L'estimation des évolutions génétiques à partir de semence congelée leur est tout à fait complémentaire, dans la mesure où elle est non limitée en termes de caractères mesurés et ne dépend pas du modèle utilisé pour l'évaluation. De fait, la semence congelée des verrats nés en 1977, évoqués ci-dessus, a été à nouveau utilisée au début des années 2000 pour estimer les évolutions génétiques sur la période 1977-1998 pour un grand nombre de caractères mesurés sur le porc en croissance dans les races LW et LR (Bazin et al, 2003), complétée en race LW par des estimations pour les caractères de reproduction, de comportement (Canario et al, 2007a ;Tribout et al, 2010 ;Canario et al, 2014 ;Silalahi et al, 2016 ;2017).…”

“…Survie des porcelets et aptitudes maternelles La sélection sur le nombre de nés totaux par portée s'est accompagnée d'un accroissement du nombre et de la proportion de mort-nés et, dans une moindre mesure, de la mortalité naissance-sevrage (Canario et al, 2007b ;Guéry et al, 2009 ;Silalahi et al, 2016 ;Silalahi et al, 2017). L'augmentation de mortinatalité pourrait être liée à des mises bas plus longues, même si aucun accroissement significatif de ce critère n'a été mis en évidence par Canario et al (2007b), qui pourraient être associées à des évolutions physiologiques (qualité des contractions utérines…) et/ou comportementales (stress accru à la mise bas) des truies (Canario et al, 2014). Le changement du critère de sélection (nés vivants au lieu de nés totaux à partir de 2002) a permis de limiter fortement l'accroissement de mortinatalité par la suite.…”
