Sow Lying Behaviors Before, During and After Farrowing
1.Introduction Behaviors carried out by sows and piglets during farrowing/lactation period have a significant impact on the well-being and even livability of piglets (e.g., crushing by the sow).Such behaviors as influenced by the stage of farrowing and environmental condition, e.g.,provision of localized heat source for the piglets, have not been fully investigated.Our hypothesis was that location of the creep heat source would impact the lying pattern of the sow,with more time spent on her udder side facing the heat source to accommodate suckling of the piglets.Therefore, the main objective of the study was to test the hypothesis through quantifying sows dynamic and postural behaviors (lying, sitting, standing, kneeling, and moving) before,during and after farrowing with absence or presence of the creep heat source (heat lamp).
