Table 4 Effects of constant chronic heat stress on pH value of small intestine segments in growing-finishing pigs

From: Alterations in intestinal microbiota composition coincide with impaired intestinal morphology and dysfunctional ileal immune response in growing-finishing pigs under constant chronic heat stress

  1. 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). Data were expressed as mean ± SEM (n = 8 for TN and PF, n = 7 for HS). Treatments with different superscript letters were significantly different at P < 0.05
