Fig. 2From: Alterations in intestinal microbiota composition coincide with impaired intestinal morphology and dysfunctional ileal immune response in growing-finishing pigs under constant chronic heat stressEffects of constant chronic heat stress on the ultrastructure of small intestine segments in growing-finishing pigs by electron microscopy (scale bar 2 μm). The red arrows indicated the location of tight junction structure. TN, thermal neutral conditions (25 ± 1 °C); HS, heat stress conditions (35 ± 1 °C); PF, pair-fed with HS under TN conditions (25 ± 1 °C)Back to article page
