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 …

Efforts to understand biological functions and develop management schemes specific to Bos
indicus-influenced cattle raised in tropical and subtropical environments are critical to meet …

Bone defect regeneration is a complex process that involves the coordination of a variety of
different type of cells. As bone tissues are innervated and rich in nerve fibers, the …

The onset of productive life in dairy cattle, concomitant to parturition, is accompanied by a
substantial decrease in fertility in comparison with non-lactating, nulliparous heifers …

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 …

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 …

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 …

Pregnancy loss is a major contributing factor to reproductive inefficiency in both the beef and
dairy industries. Sires can have a significant influence on the amount of pregnancy loss; …

The objective was to evaluate the effect of service sire on pregnancy results during different
periods of embryonic and fetal development. Angus cows (n= 658) were timed artificially …

Pregnancy loss (PL) has important impacts on the profitability of livestock production
systems, although it is not widely reported, particularly in Bos indicus cattle. The present …
