Superovulation protocols have evolved greatly over the past 40 to 50 years. The
development of commercial pituitary extracts and prostaglandins in the 1970s, and partially …

During the last decade, researchers have studied the differences in the reproductive
physiology between Bos taurus and Bos indicus breeds. This manuscript focuses on the …

Abstract Knowledge of follicular wave dynamics obtained through the use of real-time
ultrasonography and the development of the means by which follicular wave dynamics can …

Superovulation protocols have improved greatly since the early days of bovine embryo
transfer when purified gonadotrophins were not available, follicular wave dynamics were …

The present study investigated the effect of Holstein donor category (cows vs. heifers) and
climate variation (hot vs. cooler season) on the efficiency of in vivo embryo production …

Multiple ovulation (superovulation) and embryo transfer has been used extensively in cattle.
In the past decade, superstimulatory treatment protocols that synchronise follicle growth and …

The aim of this study was to evaluate the effect of a co-treatment of follicle-stimulating
hormone (FSH) plus equine chorionic gonadotrophin (eCG) on serum insulin and insulin …

This study evaluated embryo production after superovulation (SO) with a reduced number of
FSH applications and increased eCG dose in 26 Bos taurus× Bos indicus donors. On Day 0 …

The present study evaluated superovulatory responses and in vivo embryo production in
cows treated with FSH starting 1 or 2 days after ovum pick-up (OPU). Thirty-three non …

In recent decades, many significant improvements have taken place accompanying different
assisted reproductive biotechnologies like estrous synchronization, artificial insemination …
