Evaluation of a modified GnRH-based timed-AI protocol associated with estrus detection in beef heifers inseminated with sex-selected or conventional semen
(Elsevier B.V., 2018-09-15)
The main objective was to compare pregnancy per Al (P/AI) between sex-selected and conventional semen in cyclic beef heifers subjected to a 5-day Co-synch plus CIDR protocol and evaluated the usefulness of an estrus detection ...
Impacts of estrus expression and intensity during a timed-ai protocol on variables associated with fertility and pregnancy success in bos indicus-influenced beef cows1
(2018-01-01)
This experiment evaluated the impacts of estrus expression and intensity, estimated by physical activity during a timed-AI protocol, on reproductive performance of Bos indicus-influenced beef cows. A total of 290 lactating, ...
Detección de estro por observación visual y el sistema de parche estrus alert en vacas charolais mestizas sincronizadas
(2013)
The success in any extensive raising program, requires from the qualify personnel the correct detection and identification of the different primarily and secondary signs of heat on cows. The objective of the actual study ...
The effect of clitoral stimulation post artificial insemination on pregnancy rates of multiparous Bos indicus beef cows submitted to estradiol/progesterone-based estrus synchronization protocol
(Oxford Univ Press Inc, 2020-07-01)
Clitoral stimulation after artificial insemination (AI) in beef cattle is a common practice utilized by AI technicians; however, the effect of clitoral stimulation during fixed-time AI (TAI) is still unknown. The objective ...
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 ...
