Animal Board Invited Review: Meta-analysis of genetic parameters for resilience and efficiency traits in goats and sheep.Genetic selection focused purely on production traits has proven very successful in improving the productive performance of livestock.  The aim of this study was to perform a meta-analysis of genetic parameters for production, efficiency and health traits in sheep and goats.  A threelevel meta-analysis model was fitted.  Results of this meta-analysis provide evidence of genetic antagonism between production and health in dairy sheep and goats.
