Pregnancy loss in beef cattle causes both management and economic challenges to a
producer. A meta-analysis was conducted to quantify reproductive failures that occur during …

Fixed-time artificial insemination (FTAI) has been regarded as the most useful method to
increase the number of cows inseminated in a given herd. The main treatments for FTAI in …

Beef and dairy productivity depends directly on the reproductive efficiency and genetic gain
of the herd, which can be related to the appropriate use of biotechnologies, such as timed …

The aim of this review is to compare the performance of different reproductive programs
using natural service, estrus synchronization treatment before natural service (timed natural …

Fixed-time artificial insemination (FTAI) has been widely applied in South America within the
last 20 years for the genetic improvement of commercial beef herds. Most FTAI treatments for …

This review aimed to (1) summarize the results from fixed-timed artificial insemination (TAI)
fertility studies performed during the last 27 years;(2) compile and evaluate, as examples …

Using Vis-NIR spectroscopy to distinguish gestational sac from other abdominal tissues is
the key to diagnosing female rabbits' pregnancy by optical means. This study aims to …

We aimed to evaluate the reproductive performance of Nelore lactating cows submitted to a
resynchronization 12 days after timed artificial insemination (TAI) with or without a long …

We aimed to compare the effects of use of 1 or 2 mg estradiol benzoate (EB) associated with
an intravaginal progesterone (P4) device for resynchronization of ovulation 14 days after …

Artificial insemination (AI) and embryo transfer (ET) are the most widely used
biotechnologies in the world with the goal of increasing genetic gain and improving …
