Abstract
Two levels of energy and protein fed to gilts from days 3 to 15 of gestation had no effect on plasma progesterone in early pregnancy or embryo survival to day 28. However, overall, day 3 progesterone concentrations were positively related to embryo survival (P < 0.09) and inversely related to variance in survival (P < 0.07). Key words: Gilt, progesterone, embryonic loss, pregnancyKeywords
