Effect of whole-milk allowance on liveweight gain and growth of parenchyma and fat pads in the mammary glands of dairy heifers at weaning. Journal of Dairy Science, 103(6), 5061-5069. https://doi.org/10.3168/jds.2019-17126

© 2020 American Dairy Science Association The rates of development of 2 tissues in mammary glands, parenchyma (PAR) and the mammary fat pad (MFP), in response to nutrition in early life might have a major bearing on lifetime milk production. Historic... Read More about Effect of whole-milk allowance on liveweight gain and growth of parenchyma and fat pads in the mammary glands of dairy heifers at weaning.

Primary cilia distribution and orientation during involution of the bovine mammary gland (2016)
Journal Article
Biet, J., Poole, C., Stelwagen, K., Margerison, J., & Singh, K. (2016). Primary cilia distribution and orientation during involution of the bovine mammary gland. Journal of Dairy Science, 99(5), 3966-3978. https://doi.org/10.3168/jds.2015-10486

The regulation of mammary gland involution occurs through multiple levels including environmental factors, hormones, and local intramammary signals. Primary cilia (PC) are signaling organelles that sense biochemical and biophysical extracellular stim...

The effects of milking frequency on insulin-like growth factor I signaling within the mammary gland of dairy cows (2015)
Journal Article
Margerison, J., Murney, R., Stelwagen, K., Wheeler, T., & Singh, K. (2015). The effects of milking frequency on insulin-like growth factor I signaling within the mammary gland of dairy cows. Journal of Dairy Science, 98(8), 5422-5428. https://doi.org/10.3168/jds.2015-9425

In dairy cows, short-term changes in milking frequency (MF) in early lactation have been shown to produce both an immediate and a long-term effect on milk yield. The effect of MF on milk yield is controlled locally within mammary glands and could be...

Activation of signal transducer and activator of transcription 5 (STAT5) is linked to beta 1-integrin protein abundance in unilaterally milked bovine mammary glands (2015)
Journal Article

© 2015 American Dairy Science Association. Prolactin (PRL) is important in the regulation of milk synthesis in mammary epithelial cells (MEC). In cattle, circulating levels of PRL are not limiting, suggesting the possible involvement of other factors...

The effects of milking frequency in early lactation on milk yield, mammary cell turnover, and secretory activity in grazing dairy cows (2014)
Journal Article
Murney, R., Margerison, J. K., Stelwagen, K., Wheeler, T., & Singh, K. (2015). The effects of milking frequency in early lactation on milk yield, mammary cell turnover, and secretory activity in grazing dairy cows. Journal of Dairy Science, 98(1), 305-311. https://doi.org/10.3168/jds.2014-8745

In dairy cows, short-term changes of milking frequency in early lactation have been shown to produce an immediate and a long-term effect on milk yield in stall-fed cows. The effect is controlled locally within mammary glands and could be a function o...

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...
