Abstract

This study aimed to compare the reproductive efficiency of dairy buffaloes subjected to TAI protocols based on progesterone, estrogen, and equine chorionic gonadotrophin (P4/E2+eCG) during the fall/winter (n=168) and spring/summer (n=183). Buffaloes received an intravaginal P4 device (1.0 g) plus...

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

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

In the current review the main fundamental biological differences in reproductive function between Bos taurus and Bos indicus cattle are discussed. Breed differences regarding puberty, estrous cycle patterns estrous behavior, acquisition of ovulatory capacity, ovarian structures and reproductive...

Abstract

The aim of this study was to compare estradiol benzoate (EB) and GnRH for the induction of ovulation in a TAI protocol in buffalo during the nonbreeding season. In experiment 1, 141 buffaloes (56 cows and 85 heifers) received an intravaginal P4 device (1.0 g) plus EB (2.0-mg, intramuscular [im]) at ...

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...

AbstractFull Text

The present study evaluated the hypothesis that elevated progesterone during the expected multiple ovulations could improve the embryo recovery rate in superovulated buffalo. Buffalo donors were randomly assigned into 2 groups in a cross over experimental design: Control (C-G; n=8) and progesterone ...

Abstract

The aim of the present study was to evaluate the effects of the PGF treatment given at the onset of a synchronization of ovulation protocol using a norgestomet (NORG) ear implant on ovarian follicular dynamics (Experiment 1) and pregnancy per AI (P/AI; Experiment 2) in cyclic (CL present) Bos...

AbstractFull Text

The aim of this study was to evaluate the effect of using two progestagens (progesterone intravaginal device or norgestomet subcutaneous implant) in the follicular response and pregnancy rate of two categories of buffaloes (nulliparous and multiparous) which were synchronized for timed artificial ...
