Effects of two estradiol esters (benzoate and cypionate) on the induction of synchronized ovulations in Bos indicus cows submitted to a timed artificial insemination protocol
J. N. S. Sales,J. N. S. Sales,J.B.P. Carvalho,G. A. Crepaldi,R. S. Cipriano,José Octavio Jacomini,J. R. G. Maio,José Camisão de Souza,Guilherme de Paula Nogueira,Pietro Sampaio Baruselli +9 more
TL;DR: Both esters of estradiol administered either at P4 device removal (EC) or 24 h later (EB) were effective in inducing an LH surge which resulted in synchronized ovulations and similar P/AI in suckled Bos indicus beef cows submitted to TAI.
Journal ArticleDOI
Equine chorionic gonadotropin improves the efficacy of a progestin-based fixed-time artificial insemination protocol in Nelore (Bos indicus) heifers.

TL;DR: The presence of a CL (and/or onset of puberty) must be considered in setting up FTAI programs in heifers and eCG may be an important tool for the enhancement of follicular growth, ovulation, size and function of the subsequent CL, and pregnancy rates in progestin-based FTAI protocols in Bos indicus heifer.
Journal ArticleDOI
Importance of estrus on pregnancy per insemination in suckled Bos indicus cows submitted to estradiol/progesterone-based timed insemination protocols.
M. F. Sá Filho,José E. P. Santos,Roberta Machado Ferreira,J. N. S. Sales,Pietro Sampaio Baruselli +4 more
TL;DR: Cows that displayed estrus had better ovarian responses (i.e., larger follicles at TAI, a greater ovulation rate, larger CL, and greater P4 concentrations) following an estradiol/P4-based synchronization protocol.
Journal ArticleDOI
Timed embryo transfer programs for management of donor and recipient cattle
Pietro Sampaio Baruselli,Roberta Machado Ferreira,J. N. S. Sales,Lindsay Unno Gimenes,M. F. Sá Filho,C. M. Martins,C. A. Rodrigues,Gabriel A. Bó +7 more
TL;DR: In this paper, the authors focus on the importance of orchestrating donor and recipient management to assure better logistics of procedures to achieve more desirable results with embryo collection and transfer, and provide clear evidence that the use of FTAI in superstimulated donors and FTET in embryo recipients eliminates the need to detect estrus with satisfactory results.
Journal ArticleDOI
Fixed-time AI protocols replacing eCG with a single dose of FSH were less effective in stimulating follicular growth, ovulation, and fertility in suckled-anestrus Nelore beef cows
TL;DR: In conclusion, FSH failed to stimulate final follicular growth, ovulation, and conception rate in sucked-anestrous beef cows submitted to TAI as effectively as eCG, however, physiological effects of eCG seem to be more evident in cows with a lesser BCS.
