Abstract

This study assessed the effect of feeding level on progesterone concentration in the caudal vena cava during early pregnancy in gilts. Twenty-four Landrace gilts were allocated to either a high (2.8±0.02) or a low (1.5±0.01kg day-1) feeding level at Day 0 of pregnancy. Serial blood samples were collected every 15min for 3h before and 3h after feeding on Days 6 and 9 of pregnancy. Embryo survival and development as well as in vitro luteal progesterone production were assessed at Day 10 of pregnancy. Progesterone concentration in the vena cava was pulsatile with gilts on the high feeding level having more pulses compared with Low gilts on Day 9 of pregnancy (P
