Conceptus development in mammals depends on an intra-uterine environment filled with histotroph that includes molecules that are secreted by uterine epithelia and/or selectively transported into the uterine lumen. In pigs, total recoverable glucose, fructose, arginine, leucine and glutamine increase in histotroph with advancing days of the peri-implantation period of pregnancy and in allantoic fluid later in gestation. During pregnancy, the uterine luminal epithelium (LE...
