(Elsevier B.V., 2013)
Ovarian follicle diameter at timed insemination and estrous response influence likelihood of ovulation and pregnancy after estrous synchronization with progesterone or progestin-based protocols in suckled Bos indicus cows
(Amsterdam, 2010)
The objectives of the present study were to evaluate factors associated with estrous synchronization responses and pregnancy per insemination (P/AI) in Bos indicus beef cows submitted to progesterone-based fixed-time ...

Technological Evolution of Hormone Delivery Systems for Estrous Synchronization in Cattle
(Pashupati Foundation, 2014-02)
This paper reviews the evolution of hormone delivery systems and discusses future technological trends in the field. From intravaginal devices to recent advances in nano and microcapsules will be reviewed. The description ...
Probability of pregnancy to artificial insemination either after detected oestrus or at a fixed time in dairy cows: Influence of intrinsic and extrinsic factors in a large-scale, on-farm study
(2021-05-01)
The first aim of this study was to determine the influence of the procedures [hormonal treatments for fixed time artificial insemination (FTAI) versus insemination at spontaneous oestrus (SEAI)] on several sequential ...
Eficiência do estímulo hormonal e bioestimulação na taxa de ovulação, indução e sincronização do estro em caprinos.
(In: SIMPÓSIO NACIONAL DE REPRODUÇÃO ANIMAL, 6., 1988, Belo Horizonte. Anais... Campinas: Fundacao Cargill, 1988. Cap. 20, p. 309-328., 1988)
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
(ElsevierNew York, 2012-08)
The effects of estradiol benzoate (EB) and estradiol cypionate (EC) on induction of ovulation after a synchronized LH surge and on fertility of Bos indicus females submitted to timed AI (TAI) were evaluated. In Experiment ...
Fertility Rates Following Fixed-Time Artificial Insemination in Dairy Heifers in a Practical Progesterone-Based Protocol
(Universidade Federal do Rio Grande do Sul (UFRGS), 2011-01-01)
Background: In bovines, more efficient management practices are important for maximizing profitability. In order to increase the pregnancy rates in artificial insemination (AI) programs, several hormonal protocols were ...
