Low protein intake during the preconception period in beef heifers affects offspring and maternal behaviour (2019)
Journal Article
Miguel-Pacheco, G. G., Perry, V. E., Hernandez-Medrano, J. H., Wapenaar, W., Keisler, D. H., & Voigt, J. P. (2019). Low protein intake during the preconception period in beef heifers affects offspring and maternal behaviour. Applied Animal Behaviour Science, 215, 1-6. https://doi.org/10.1016/j.applanim.2019.04.003

Maternal low protein diets prior to conception alter embryo and fetal development and are associated with detrimental outcomes in the offspring in many species. The aim of this study in beef cattle was to investigate the effect of preconception dieta...

Subacute ruminal acidosis reduces sperm quality in beef bulls (2016)
Journal Article
Callaghan, M., McAuliffe, P., Rodgers, R., Hernandez-Medrano, J., & Perry, V. (in press). Subacute ruminal acidosis reduces sperm quality in beef bulls. Journal of Animal Science, 94, https://doi.org/10.2527/jas.2015-0235

Breeding bulls are commonly fed high-energy diets, which may induce subacute ruminal acidosis (SARA). In this experiment, 8 Santa Gertrudis bulls (age 20 ± 6 mo) were used to evaluate the extent and duration of effects of SARA on semen quality and th...

Gestational dietary protein is associated with sex specific decrease in blood flow, fetal heart growth and post-natal blood pressure of progeny (2015)
Journal Article
Hernandez Medrano, J., Copping, K. J., Hoare, A., Wapanaar, W., Grivell, R., Kuchel, T., …Perry, V. E. (2015). Gestational dietary protein is associated with sex specific decrease in blood flow, fetal heart growth and post-natal blood pressure of progeny. PLoS ONE, 10(4), Article e0197942. https://doi.org/10.1371/journal.pone.0125694

The incidence of adverse pregnancy outcomes is higher in pregnancies where the fetus is male. Sex specific differences in feto-placental perfusion indices identified by Doppler assessment have recently been associated with placental insufficiency and...

Human Reproduction, 29(8), 1749-1763. https://doi.org/10.1093/humrep/deu144

study question: Is it possible to restore ovarian function and natural fertility following the cryopreservation and autotransplantation of whole ovaries, complete with vascular pedicle, in adult females from a large monovulatory animal model species...
