PSIII-7 Using automated monitoring devices to predict pregnancy by artificial insemination in grazing beef cows. Open
We recently validated an automated monitoring device (i.e., accelerometers) for estrous detection in grazing beef cows with 91% of accuracy, but whether this methodology predicts pregnancy by artificial insemination (AI) still unclear. We …

PSV-20 Metabolomic and transcriptomic landscape of the bovine uterine lumen in the second week of the estrous cycle. Open
In cattle, during the second week of pregnancy, the embryo transitions from the spherical, zona-enclosed blastocyst to the initially elongated conceptus. The overarching hypothesis is that endometrial function changes temporally to support…

331 Importance of sex-steroids to uterine receptivity for pregnancy in beef cattle. Open
In cattle, pregnancy success is mainly determined by the endometrial function from a week prior to conception to three weeks after (i.e., the preimplantation period). The master regulators of endometrial function are the sex-steroids (estr…

425 Award Talk: The importance of estrus expression and endometrial function for the pregnancy success in beef cattle. Open
In cattle, pregnancy success is partially limited by estrus expression, uterine function, and breed composition. Whole-animal and in vitro systems approaches were used to define the importance of such components to fertility. In objective …

102 Estradiol and follicular growth are associated with estrous behavior monitored by an accelerometer in grazing beef cows Open
In beef cattle, 40% of cows that display estrus do not remain pregnant after embryo transfer (ET). Estrus is a physiological behavior influenced by the concentration of sex-steroids. The use of accelerometer devices for estrus detection is…

77 Assessing abundance of pregnancy markers among fertility-classified beef cows Open
In beef cattle, for a single pregnancy opportunity, only 60% of cows will remain pregnant. It is possible that uterine dysfunction prevents adequate embryo signaling and subsequent placentation. Our aim was to compare the abundance of mole…

Solutions to the fertility equation in beef embryo recipients Open
In beef cattle operations that conduct embryo transfer, the overall success depends on the pregnancy outcome that results from every pregnancy opportunity. In this review, we dissected the main components that determine if a recipient will…

15 Search for Non-Genomic Markers as Puberty Predictors in<i>Bos Indicus</i> Cattle Open
Brahman cattle are used for crossbreeding due to their maternal ability, heat, and parasite tolerance. Brahman displays delayed attainment of puberty compared with taurine breeds. The objective was to identify molecular markers in the bloo…
