In the ISG, absolute liver weight and liver weight
as a percent of EBW were reduced (P < 0.04; 17.9 and
13.6%, respectively) and total viscera weight tended
(P < 0.10) to be reduced (6.5%) in IUHS compared
to IUTN pigs (Table 3). In the FSG, head weight was
reduced (P ≤ 0.05; 4.9%) in IUHS compared to IUTN
pigs (Table 3). A decrease (P < 0.01) in total viscera
(450 g), liver (80 g), spleen (20 g), and blood (190 g)
weight was observed in pigs in postnatal HS compared
to TN environments (Table 3). Total viscera, liver, and
spleen weight as a percent of EBW were decreased
(P < 0.02) 5.9, 7.6, and 15.8%, respectively, in postnatal
HS compared to TN control pigs (Table 3). No
other in utero or postnatal organ and carcass weight
differences were detected (Table 3).
