Impact of dietary l-arginine supply during early gestation on myofiber development in newborn pigs exposed to intra-uterine crowding

Table 5 Myofiber characteristics in the Semitendinosus muscle of selected offspring born from oviduct ligated (OL; non crowded) and intact (IN; relatively crowded) sows fed an unsupplemented (Ctrl) or l-arginine supplemented diet (ARG) from d 14 to 28 of gestation¹

¹Results are presented as least squares means of interactions between the two main factors extent of intra uterine crowding and dietary treatment and pooled SEM
²Probability values for the effects of extent of intra uterine crowding (IUC), dietary treatment (DIET), birth weight (BtW), and interactions IUC × DIET and DIET × BtW
³The secondary-to-primary myofiber ratio, calculated by dividing the number of secondary with the number of primary myofibers in the dark portion of the Semitendinosus muscle.
^a,bWithin a row for the main factor treatment, least squares means without a common superscript differ (P < 0.05)
^x,yWithin a row for the main factor treatment, least squares means without a common superscript differ (0.05 < P < 0.10)
