Genetic analysis of litter size and weights, and of farrowing duration in Large White and French Landrace sows

Low heritability estimates were obtained for litter size and mortality traits. Numbers of piglets stillborn had unfavourable geneticcorrelations with Numbers of piglets born in total, but low genetic correlations with…

Operational criteria for meat quality : relations with exudate loss

The aim of this study was to compare the quality of exudate loss prediction by several quality criteria at three different times post mortem. The correlations between quality criteria (pH,…

Energy recovery techniques : heat pumps

Heat pumps are systems composed of two heat exchangers and a heat-carrying liquid that can take up energy from a heat source (e.g. the ground, air washers or a biological…

Incidence of growing pig housing conditions, fully slatted floor or straw bedding, on technical efficiency

Two housing systems (fully slatted floor vs straw litter) were assessed with respect to their technical efficiency. The comparison was carried out under two contrasting seasons, in order to take…
