Abstract

Persistent mating induced endometritis (PMIE) is a major cause of infertility in mares. Routine therapies such as post-breeding uterine lavage with saline or administration of oxytocin or prostaglandin (PGF2) often fail to eliminate uterine infection. In a pilot study we wanted to investigate the...

Abstract

Uterine contractions were ultrasonically recorded (t=20 min) in 50 maiden mares (3-4 years old) within 0-6 h after hCG induced ovulation. The mares were divided into 5 groups (n=10, respectively). Group 1 was inseminated conventionally into the uterine body, while Group 2 was inseminated onto the...

Abstract

Controlled reproduction in small ruminants is an important economic factor. Of major interest is oestrus induction or synchronization as a prerequisite for timed insemination as well as the control of seasonality and increase of numbers of offspring which can be achieved by medication or taking...

Abstract

This review describes factors that affect conception rate after synchronization of ovulation and timed artificial insemination. Intervals of 7 days between GnRH and PGF, 48 hours to the second GnRH treatment and a further 16 to 20 hours to the timed insemination have been proven to be most...
