Cows that exhibit estrus within 24 h of fixed-time AI have elevated concentrations of estradiol and greater pregnancy rates compared with cows not in estrus. Our objective was to determine whether estradiol, estrus, or both had an effect on uterine

To determine whether abnormal laxity of hip joints of canine pups with genetic predisposition to hip dysplasia (HD+) is related to ingestion of milk-borne hormones. 7 female Labrador Retrievers with HD+ and 8 with low predisposition to hip dysplasia (HD-)
Estrogen prepares the uterus for implantation and is highly conserved in mammals. However, administration of estrogen to pigs earlier than normal conceptus secretion is characterized by complete embryonic mortality by days 15-18. The objective of this study was to characterize
In pigs, administration of estrogen to gilts on Days 9 and 10 of pregnancy causes conceptus fragmentation and death between Days 15 and 18 of gestation. Conceptus degeneration is associated with breakdown of the microvilli surface glycocalyx on the lumenal

The objective was to determine the effect of supplemental estrogen (estradiol cypionate, ECP) at dry-off on temporal changes in concentrations of lactose in blood plasma of Holstein cows as an indicator of rate of mammary involution. Thirty-two Holstein cows (8/group)
