Typically, bovine embryos are transferred into recipient females about day 7 after estrus or
anticipated ovulation, when the embryo has reached the blastocyst stage of development …

In vitro embryo production (IVP) in cattle has gained worldwide interest in recent years, but
the efficiency of using IVP embryos for calf production is far from optimal. This review will …

Paternal characteristics and exposures influence physiology and disease risks in progeny,
but the mechanisms are mostly unknown. Seminal fluid, which affects female reproductive …

Seminal fluid is often assumed to have just one function in mammalian reproduction,
delivering sperm to fertilize oocytes. But seminal fluid also transmits signaling agents that …

OBJECTIVE: To assess whether inadequate, thin endometrium (< 7 mm), after failure to
expand with standard treatment options, will be responsive to cytokine treatment. DESIGN …

Heat stress causes a large decline in pregnancy success per insemination during warm
times of the year. Improvements in fertility are possible by exploiting knowledge about how …

Domestication and selective breeding has resulted in over 1000 extant cattle breeds. Many
of these breeds do not excel in important traits but are adapted to local environments. These …

Background Identification of single nucleotide polymorphisms (SNPs) for specific genes
involved in reproduction might improve reliability of genomic estimates for these low …

The transition from pregnancy to lactation (ie the transition period) is a time of significant
metabolic challenge, with a several-fold increase in a cow's requirement for energy, protein …

Heat stress is a major threat to cattle reproduction today. It has been shown that the effect of
high temperature not only has a negative effect on the hormonal balance, but also directly …
