Evaluation of long-term CIDR-based estrus synchronization protocols in primiparous two-year-old beef cows
(University of Missouri--Columbia, 2015)
Reproductive management of two-year-old beef cows presents a unique challenge in managing a beef herd, since this age group of females typically experiences the highest incidence of reproductive failure. Strategic management ...
Timing GnRH administration with split-time artificial insemination following administration of CIDRbased protocols to synchronize estrus and ovulation in beef heifers and cows
(University of Missouri--Columbia, 2015)
Split-time artificial insemination (STAI) was developed as a novel breeding strategy that delays insemination by 20 to 24 h for cows and heifers that fail to express estrus prior to a predetermined fixed time. Split-time ...
Considerations for reproductive management of bos indicus-influenced beef heifers
(University of Missouri--Columbia, 2017)
The Bos indicus species of beef cattle presents a number of unique reproductive challenges, especially with regard to those that influence reproductive efficiency including timely attainment of puberty, response to certain ...
Comparison of long-term CIDR-based protocols to synchronize estrus and ovulation prior to fixed-time artificial insemination in postpartum beef cows
(University of Missouri--Columbia, 2012)
This experiment compared two long-term CIDR-based protocols to synchronize estrus and ovulation prior to fixed-time AI (FTAI) in postpartum beef cows. Cows assigned to the 14-19 d CIDR-PG protocol (n = 196) received CIDR ...
Comparison of long-term CIDR-based protocols to synchronize estrus in postpartum beef cows
(University of Missouri--Columbia, 2011)
Estrus synchronization and artificial insemination are two of the most important management practices available to producers to increase reproductive performance in a beef cow-calf operation. Unfortunately, a small number ...
Evaluating progestin-based protocols to control estrous cycles of beef heifers prior to timed artificial insemination
(University of Missouri--Columbia, 2018)
The recent development of split-time artificial insemination as a breeding strategy improved reproductive outcomes following treatment with the 14d CIDR[copyright]-PG protocol; however, STAI has not been evaluated with ...
Comparison of CIDR-based protocols to synchronize estrus in beef heifers
(University of Missouri--Columbia, 2007)
Estrus synchronization and artificial insemination (AI) are reproductive management techniques that allow beef producers to enhance the reproductive efficiency and genetic composition of their cow herd. However, U.S. beef ...
Comparison of controlled internal drug release (CIDR)-based protocols to synchronize estrus and facilitate artificial insemination (AI) in postpartum beef cows
(University of Missouri--Columbia, 2008)
Artificial insemination (AI) and estrous synchronization are reproductive technologies that enable beef producers to efficiently improve herd genetics. The recent development of protocols designed to synchronize estrus and ...
Comparison of long-term progestin-based protocols to synchronize estrus in beef heifers
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Experiment 1 evaluated two long-term progestin-based and controlled internal drug release estrus synchronization protocols to determine their potential ...
