Clinical and research applications of real-time ultrasonography in bovine reproduction: A review
Download1994
Ambrose, Divakar J., Burton, Bruce, Rajamahendran, Rajadurai
Transrectal real-time ultrasonography has proved to be a rapid and reliable technique for studying reproductive functions in cattle. Through ultrasonography it is now established that follicular growth occurs in wave-like patterns during each estrous cycle. It has been shown that follicular...

Kastelic, John P., Small, Julie A., Ambrose, Divakar J., Colazo, Marcos G.
The objective of this study was to compare 2 enzyme immunoassays (EIAs) with a radioimmunoassay (RIA) as to sensitivity and accuracy in the measurement of the progesterone (P4) concentration in bovine plasma, skim milk, and whole milk. The 72 samples from 24 lactating dairy cows expected to have...

Differences in whole blood gene expression associated with infection time-course and extent of fetal mortality in a reproductive model of type 2 porcine reproductive and respiratory syndrome virus (PRRSV) infection
Download2016
Ladinig, Andrea, Stothard, Paul, Wilkinson, Jamie M., Kommadath, Arun, Plastow, Graham S., Harding, John C. S., Bao, Hua, Lunney, Joan K.
Porcine Reproductive and Respiratory Syndrome Virus (PRRSV) infection of pregnant females causes fetal death and increased piglet mortality, but there is substantial variation in the extent of reproductive pathology between individual dams. This study used RNA-sequencing to characterize the whole...
