This review provides evidence for key roles of both fructose and lactate in support of key metabolic pathways required for growth and development of fetal-placental tissues, implantation and placentation. The uterus and placenta of ungulates convert glucose to fructose via the polyol pathway.

At weaning (21 d of age), IUGR pigs and litter mates with normal birth weights (NBW) were assigned randomly to 1 of the 2 groups, namely, supplementation with 1% Gly or 1.19% l-alanine (isonitrogenous control) to a corn- and soybean meal-based diet.

Research concerning ISGs, performed from 1995 through 2023, is reviewed in this manuscript.
Abstract: Expression of the classical interferon (IFN) stimulated genes (ISGs) increases in the endometrial stroma and glandular epithelium (GE) through activation of signal transducer and activator of transcription (STAT) signaling in response to the secretion of IFN tau (IFNT) and IFN gamma (IFNG) by the conceptuses of ruminants, including cattle and sheep, and pigs, respectively.
