Bone morphogenetic proteins (BMPs) are firmly implicated as intraovarian regulators of follicle development and steroidogenesis. Here we report a microarray analysis showing that treatment of cultured bovine theca cells (TC) with BMP6 significantly (...

Neohormones as biomarkers of reproductive health (2013)
Journal Article

Neohormone systems are defined as evolutionarily new endocrine or paracrine adaptations that supplement basic physiologic functions and define mammalian success. The relaxin family of peptide hormones are typical neohormones. Because they define the... Read More about Neohormones as biomarkers of reproductive health.

Brief maternal exposure of rats to the xenobiotics dibutyl phthalate or diethylstilbestrol alters adult-type Leydig cell development in male offspring (2013)
Journal Article
Ivell, R., Heng, K., Nicholson, H., & Anand-Ivell, R. (2013). Brief maternal exposure of rats to the xenobiotics dibutyl phthalate or diethylstilbestrol alters adult-type Leydig cell development in male offspring. Asian Journal of Andrology, 15(2), https://doi.org/10.1038/aja.2012.138

Maternal exposure to estrogenic xenobiotics or phthalates has been implicated in the distortion of early male reproductive development, referred to in humans as the testicular dysgenesis syndrome. It is not known, however, whether such early gestatio...

On-farm methane measurements during milking correlate with total methane production by individual dairy cows (2012)
Journal Article
Garnsworthy, P., Craigon, J., Hernandez-Medrano, J., & Saunders, N. (2012). On-farm methane measurements during milking correlate with total methane production by individual dairy cows. Journal of Dairy Science, 95(6), https://doi.org/10.3168/jds.2011-4605

The objective of this study was to investigate whether measurement of methane emissions by individual dairy cows during milking could provide a useful technique for monitoring on-farm methane emissions. To quantify methane emissions from individual c... Read More about On-farm methane measurements during milking correlate with total methane production by individual dairy cows.

Variation among individual dairy cows in methane measurements made on farm during milking (2012)
Journal Article
Garnsworthy, P., Craigon, J., Hernandez-Medrano, J., & Saunders, N. (2012). Variation among individual dairy cows in methane measurements made on farm during milking. Journal of Dairy Science, 95(6), https://doi.org/10.3168/jds.2011-4606

The objective of this study was to quantify on-farm variation between and within cows in methane emissions measured during milking, and to determine which factors are related to this variation. Methane emission rate during milking (MERm) was recorded... Read More about Variation among individual dairy cows in methane measurements made on farm during milking.

Mechanical properties of the bovine claw horn during lactation (2012)
Journal Article
Winkler, B., & Margerison, J. K. (2012). Mechanical properties of the bovine claw horn during lactation. Journal of Dairy Science, 95(4), 1714-1728. https://doi.org/10.3168/jds.2011-4489

Claw horn disorders are one of the main causes of lameness in dairy cows globally. This study aimed to develop material testing techniques to assess changes in the mechanical properties of bovine claw horn (BCH) and to compare these mechanical proper...

Biosecurity on cattle farms: a study in North-West England (2012)
Journal Article
Brennan, M. L., & Christley, R. M. (2012). Biosecurity on cattle farms: a study in North-West England. PLoS ONE, 7(1), Article e28139. https://doi.org/10.1371/journal.pone.0028139

Background: Few studies have considered in detail the range of biosecurity practices undertaken on cattle farms, particularly within the UK. In this study, 56 cattle farmers in a 100 km2 area of north-west England were questioned regarding their on-f... Read More about Biosecurity on cattle farms: a study in North-West England.

Differential acetylation of histone H4 lysine during development of in vitro fertilized, cloned and parthenogenetically activated bovine embryos (2008)
Journal Article

Oocyte control of granulosa and theca cell function may be mediated by several growth factors via a local feedback loop(s) between these cell types. This study examined both the role of oocyte-secreted factors on granulosa and thecal cells, cultured...
