Abstract

Protocols designed to control follicular wave dynamics and ovulation in cattle have reduced, and even eliminated, the need for estrus detection. The addition of progestin-releasing devices and gonadotropin treatments, such as equine chorionic gonadotropin, have provided possibilities for increased...

Abstract

The development of treatments that control follicular wave dynamics during the bovine oestrous cycle has resulted in interesting possibilities for the precise control of follicular wave emergence and the time of ovulation. For superstimulation, follicular wave emergence can be controlled by...

Abstract

Our expanding knowledge of the control of follicular wave dynamics during the bovine oestrous cycle has resulted in renewed enthusiasm for the prospects of precisely controlling the follicular and luteal dynamics and the time of ovulation. Follicular wave development can be controlled mechanically...

Abstract

Recent protocols which provide possibilities for oestrus synchronization that is precise enough to permit fixed-timed artificial insemination or embryo transfer without the need for oestrus detection are described. Synchronization of oestrus and ovulation; the use of GnRH, pLH, progesterone and...

Abstract

In the 1st experiment, 18 beef heifers were assigned to non-ablation and 20 to ablation groups. In non-ablated heifers, superstimulatory treatment was given as a single subcutaneous injection (Follitropin-V, 400 mg) at mid-dioestrus to coincide with emergence of the spontaneous follicular wave 8-12 ...
