Abstract

Compared to Bos taurus breeds, Bos indicus breeds of cattle present several differences in reproductive physiology. Follicular diameter at deviation and at the time of ovulatory capability are smaller in B. indicus breeds. Furthermore, B. indicus breeds have a greater sensitivity to gonadotropins,...

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

Greater milk production in modern dairy cattle has led to greater nutritional needs, increased rates of post-partum anoestrus, reduced oestrus detection rates, lower conception and pregnancy rates and a higher incidence of embryonic mortality. In addition, larger herds have resulted in management...
