Autor: Rafael R. Domingues, Joao Paulo N. Andrade, Thiago O. Cunha, Guilherme Madureira, Uzi Moallem, Victor Gomez-Leon, Joao Paulo N. Martins, Milo C. Wiltbank

Publikováno v: JDS Communications, Vol 4, Iss 2, Pp 149-154 (2023)

Because progesterone (P4) is essential for pregnancy establishment and maintenance, we investigated the effect of increased concentrations of P4 on embryonic attachment and concentrations of pregnancy-associated glycoproteins (PAG). Additionally, we

Publikováno v: Reproduction.

Cattle are generally considered a monovular species; however, recently a bovine high fecundity allele, termed the Trio allele, was discovered. Carriers of Trio have an elevated ovulation rate (3 to 5) while half-sibling noncarriers are monovular. Car

Autor: Milo C. Wiltbank, Pedro L.J. Monteiro, Rafael R. Domingues, João Paulo N. Andrade, Megan A. Mezera

Publikováno v: Animal, Vol 17, Iss , Pp 100827- (2023)

This manuscript reviews the mechanisms that maintain the corpus luteum (CL) of pregnancy in ruminants. In mammals, ovulation and luteinization of the remaining cells in the CL are due to a surge in Luteinizing Hormone (LH). In cattle, continued secre

Accessory corpus luteum induced by human chorionic gonadotropin on day 7 or days 7 and 13 of the estrous cycle affected follicular and luteal dynamics and luteolysis in lactating Holstein cows

Publikováno v: Journal of Dairy Science, Vol 105, Iss 3, Pp 2631-2650 (2022)

ABSTRACT: Our objective was to determine the effect of inducing an accessory corpus luteum (CL) with human chorionic gonadotropin (hCG; 3,300 IU) on d 7 (hCG7) or 2 accessory CL with hCG on d 7 and 13 (hCG7+13) of the estrous cycle in noninseminated
