Comparison between Single- and Group-housed Pregnant Sows for Direct and Indirect Physiological, Reproductive, Welfare Indicators and Gene Expression Profiling

Single- and group-housed pregnant sows were assessed during 8 weeks (4th and 8th to 14th) with regard to physiological, reproductive, welfare indicators and gene expression profiling. Compared to single-housed sows, group-housed sows had decreased non-return to estrus at 56 days after artificial ins...

Description
Summary:Single- and group-housed pregnant sows were assessed during 8 weeks (4th and 8th to 14th) with regard to physiological, reproductive, welfare indicators and gene expression profiling. Compared to single-housed sows, group-housed sows had decreased non-return to estrus at 56 days after artificial insemination (AI) (83% vs 92%) and farrowing rate (78% vs 88%), respectively. Furthermore, group-housed sows showed a higher degree (p
