Typically, bovine embryos are transferred into recipient females about day 7 after estrus or
anticipated ovulation, when the embryo has reached the blastocyst stage of development …

Simple Summary Reproductive efficiency is critical for profitability of dairy operations. The
first part of this manuscript discusses the key physiology of dairy cows and how to practically …

Reproductive failure and pregnancy loss in cattle are some of the largest economic burdens
to cattle producers and one of most perplexing factors influencing management decisions …

The primary objective was to determine if circulating concentration of bovine pregnancy-
associated glycoproteins (bPAGs) on Day 30 after artificial insemination (AI) may serve as a …

Cattle producers are limited to day 28–30 of gestation as the earliest time point for accurate
pregnancy diagnosis due to the effectiveness of ultrasound and chemical based methods …

The objective of this observational study was to identify factors associated with estrous
duration (DU) and intensity measured as the peak of activity (PA) change and subsequent …

The objective of this study was to examine the association between increased physical
activity at the moment of timed artificial insemination (AI), detected by an automated activity …

Background Pregnancy loss is a major source of infertility in dairy cows. Despite a
fertilization rate after insemination (AI) of approximately 90%, calving rates are 30%–50 …

Several tools exist to diagnose pregnancy in dairy cattle. However, substantial pregnancy
loss occurs within the first 60 d of gestation in cattle, and these losses have a profound …

This experiment evaluated the impacts of estrus expression and intensity, estimated by
physical activity during a timed-AI protocol, on reproductive performance of Bos indicus …
