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

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...

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...

AbstractFull Text

This study proved that previously manipulated hormonal mares with different schemes for synchronization of oestrus cycle - using prostaglandins and combined use of progestins and prostaglandins, fecundity remains at insemination with cryopreserved semen. Furthermore it was found preserving...

Abstract

The aim of this study was to determine the relationship between the intensity of estrus expression on the ovulatory follicle diameter (OFD) and its effect on the conception rate in zebu females managed under a FTAI program. On a random day of the estrous cycle, day 0, 308 Nellore females received...

AbstractFull Text

Some dairy cows display a pronounced reduction in first milk yield after estrus onset. The objective of this study was to evaluate the usefulness of the pronounced reduction in milk yield as an indicator of the optimal time for artificial insemination (AI). We confirmed that the frequency of a...
