The cholesterol concentration on Day 21 and the pregnancy rate were
greater (P < 0.03) in the sunflower group (148.2 6.1 mg/dL and 66.7%) than those in the
control group (116.0 6.4 mg/dL and 47.8%). In experiment 2, heifers received an in vitro–
produced embryo 7 days after the expected time of the synchronized ovulation. Heifers
were separated into two supplementation groups (sunflower, n ¼ 106 and control, n ¼ 111)
for 22 days
