Relationships between fertility and postpartum changes in body condition and body weight in lactating dairy cows
P.D. Carvalho,A.H. Souza,M.C. Amundson,Katherine S. Hackbart,M.J. Fuenzalida,M.M. Herlihy,H. Ayres,A.R. Dresch,L.M. Vieira,J.N. Guenther,Ric R. Grummer,Paul M. Fricke,Randy D. Shaver,Milo C. Wiltbank +13 more
TL;DR: For cows synchronized with a Double-Ovsynch protocol, an effect of low BCS near AI on fertility was detected, but change in BCS during the first 3 wk postpartum had a more profound effect on P/AI to first timed AI.

Relationship between circulating anti-Müllerian hormone (AMH) and superovulatory response of high-producing dairy cows.
Alessandro Souza,P.D. Carvalho,A.E. Rozner,L.M. Vieira,Katherine S. Hackbart,R.W. Bender,A.R. Dresch,J.P. Verstegen,Randy D. Shaver,Milo C. Wiltbank +9 more
TL;DR: Circulating AMH concentration was strongly associated with superovulation response, and evaluation of AMH could be used to identify cows with greater responses to superstimulation and thus improve efficiency ofsuperovulation programs in dairy cows.

Effect of dietary organic zinc, manganese, copper, and cobalt supplementation on milk production, follicular growth, embryo quality, and tissue mineral concentrations in dairy cows
Katherine S. Hackbart,Roberta Machado Ferreira,A. A. Dietsche,M. T. Socha,Randy D. Shaver,Milo C. Wiltbank,Paul M. Fricke +6 more
TL;DR: It is concluded that replacing a portion of inorganic supplemental trace minerals with an equivalent amount of these organic trace minerals increased milk production in mid-lactation, but did not affect postpartum follicular dynamics, embryo quality, or liver and luteal trace mineral concentrations.
107
Effect of maternal methionine supplementation on the transcriptome of bovine preimplantation embryos.
Francisco Peñagaricano,A.H. Souza,P.D. Carvalho,Ashley M. Driver,Rocio Gambra,Jenna Kropp,Katherine S. Hackbart,Daniel Luchini,Randy D. Shaver,Milo C. Wiltbank,Hasan Khatib +10 more
TL;DR: Evidence is provided that supplementing methionine to dams prior to conception and during the preimplantation period can modulate gene expression in bovine blastocysts.
Use of a single injection of long-acting recombinant bovine FSH to superovulate Holstein heifers: a preliminary study.
P.D. Carvalho,Katherine S. Hackbart,R.W. Bender,Giovanni M. Baez,A.R. Dresch,J.N. Guenther,A.H. Souza,Paul M. Fricke +7 more
TL;DR: A single injection of a preparation of long-acting rbFSH produced similar superovulatory responses resulting in the production of good-quality embryos when compared with a pituitary-derived FSH preparation administered twice daily for 4 days.
