TL;DR: A new method for synchronizing the time of ovulation in cattle using GnRH and PGF2α could have a major impact on managing reproduction in lactating dairy cows, because it allows for AI to occur at a known time of Ovulation and eliminates the need for detection of estrus.

TL;DR: Higher rates of LBF and steroid metabolism in lactating than in nonlactating cows may indicate chronic effects of higher feed intakes as well.
609 citations
TL;DR: Although overall synchronization rate with Ovsynch was above 85%, there were clear differences in response according to day of protocol initiation, with cows in which Ov synch was initiated at midcycle having smaller ovulatory follicles and greater pregnancy rates.
579 citations
TL;DR: A timed artificial insemination protocol that synchronized the time of ovulation using GnRH and PGF2 alpha allowed effective management of AI in lactating dairy cows without the need for estrus detection.

TL;DR: The purpose of this review is to provide a comprehensive survey of the current understanding of prolactin's function and its regulation and to expose some of the controversies still existing.
Abstract: Prolactin is a protein hormone of the anterior pituitary gland that was originally named for its ability to promote lactation in response to the suckling stimulus of hungry young mammals. We now know that prolactin is not as simple as originally described. Indeed, chemically, prolactin appears in a multiplicity of posttranslational forms ranging from size variants to chemical modifications such as phosphorylation or glycosylation. It is not only synthesized in the pituitary gland, as originally described, but also within the central nervous system, the immune system, the uterus and its associated tissues of conception, and even the mammary gland itself. Moreover, its biological actions are not limited solely to reproduction because it has been shown to control a variety of behaviors and even play a role in homeostasis. Prolactin-releasing stimuli not only include the nursing stimulus, but light, audition, olfaction, and stress can serve a stimulatory role. Finally, although it is well known that dopamine of hypothalamic origin provides inhibitory control over the secretion of prolactin, other factors within the brain, pituitary gland, and peripheral organs have been shown to inhibit or stimulate prolactin secretion as well. It is the purpose of this review to provide a comprehensive survey of our current understanding of prolactin's function and its regulation and to expose some of the controversies still existing.

TL;DR: In this article, the authors estimate economic losses sustained by major US livestock industries from heat stress, including decreased performance (feed intake, growth, milk, eggs), increased mortality, and decreased reproduction.
