Abstract

The objective was to determine the efficiency of insemination with sexed semen at spontaneous estrus and synchronisation of ovulation, and the effects of days in milk, insemination number, parity, and daily milk yield on pregnancy rates in lactating Holstein cows. A total 1,000 first to fourth...

Abstract

On commercial farms, rabbit does are subjected to a reproductive rhythm that does not account for their welfare or physiology, leading to reduced longevity and consequently high annual replacement. The European Food Safety Authority (EFSA) recommends limited and infrequent use of hormone...

Abstract

The aim of this review is to compare the performance of different reproductive programs using natural service, estrus synchronization treatment before natural service (timed natural breeding (TNB)), artificial insemination (AI) following estrus detection and timed artificial insemination (TAI) in...

Abstract

This study evaluated the effect of breed and follicular status of Boer and indigenous goats on response to superovulation and embryo yield. The oestrous cycles were synchronized with progestagen for nine days and superovulated with porcine follicle-stimulating hormone. Does were cervically...

Abstract

Two experiments were conducted to assess a hormonal strategy developed to reduce animal handling for timed artificial insemination (TAI) with sex-sorted semen. Four-hundred ninety-one (491) suckled beef cows received a progesterone (P4) intravaginal device and 2 mg intramuscular (im) injection of...

Abstract

Fixed-time artificial insemination (FTAI) is the most effective method to increase the number of females inseminated in a single day, eliminating the necessity of estrus detection. Usually the treatments for FTAI in sheep are based on the use of progesterone-releasing devices and equine chorionic...

AbstractFull Text

The success of a fixed-time artificial insemination (FTAI) program depends on a high ovulation rate during a short interval. Equine chorionic gonadotropin (eCG) has been used in FTAI protocols to improve follicular growth and thereby to produce larger, more responsive follicles for ovulation with...

AbstractFull Text

The impact of real-time ultrasound on the study of bovine reproduction has been dramatic and further development of portable ultrasound machines has given clinicians an added tool for diagnostic reproductive management. Ultrasonography with 3.0-7.5 MHz frequency linear probes is commonly used and...
