Butyrate and subacute ruminal acidosis affect abundance of membrane proteins involved with proton and short chain fatty acid transport in the rumen epithelium of dairy cows
Download2013
Steele, Michael A., Dionissopoulos, Louis, McBride, Brian W., AlZahal, Ousama, Greenwood, Sabrina L., Laarman, Anne H.
The objective of this study was to elucidate the effects of butyrate on the Short Chain Fatty Acids (SCFA) membrane transport proteins and proton membrane transport proteins in the rumen epithelium. Sixteen mid-lactation cows were fed a 44% Non-Fibre Carbohydrate (NFC) diet and divided into a...

Butyrate-mediated genomic changes involved in the non-specific host defenses, matrix remodelling and the immune response in the rumen epithelium of cows afflicted with subacute ruminal acidosis

Subacute Ruminal Acidosis (SARA) is a disorder in cattle which can lead to chronic inflammation in the rumen epithelium, known as rumenitis. Butyrate has been shown to attenuate some of the detrimental effects of inflammatory gastroenteral disorders but the molecular mechanisms mediated by...

Changes in the rumen papillae during the periparturient transition in Holstein dairy cows are accompanied by changes in abundance of proteins involved in intracellular pH regulation, but not SCFA transport

McBride, Brian W., Laarman, Anne H., Steele, Michael A., AlZahal, Ousama, Kleinberg, Adam
The objective of this study was to examine changes in SCFA transportcapacity in the rumen epithelium during the parturition transition period.Twelve pregnant, cannulated primiparous and multiparous cows were fed astandard Total Mixed Ration (TMR) for the duration of the dry period; aftercalving,...

Ruminal acidosis and the rapid onset of ruminal parakeratosis in a mature dairy cow: A case report
Download2009
Hook, Sarah E., AlZahal, Ousama, McBride, Brian W., Croom, Jim, Steele, Michael A.
A mature dairy cow was transitioned from a high forage (100% forage) to a high-grain (79% grain) diet over seven days. Continuous ruminal pH recordings were utilized to diagnose the severity of ruminal acidosis. Additionally, blood and rumen papillae biopsies were collected to describe the...
