Research ArticleOpen accessThe Effects of Subacute Ruminal Acidosis on Milk Fatty Acid Profile in Dairy CattleC. Mitchell, O. ALZahal, M.M. Or-Rashid et al.The objective of this experiment was to examine the effect of Subacute Ruminal Acidosis (SARA) on milk fatty acid (FA) profiles with emphasis on odd-chain and branched-chain FA. Sixteen multiparous Holstein dairy cows (618±35 kg of body weight, 221±32 days in milk) were used in a randomized complete-block design. During week 1, all cows received a high-forage diet (90% chopped … …American Journal of Animal and Veterinary Sciences, Vol. 11, Issue 2 · 27 Apr 2016 · 7,740 accessesView PDF Cite

Research ArticleOpen accessA Characterization of Inflammatory and Structural Markers within the Rumen Epithelium During Grain-Induced Ruminal Acidosis in Lactating Dairy CattleL. Dionissopoulos, M. A. Steele, O. AlZahal et al.The objective of this study was to characterize the mRNA and protein expression of inflammatory and structural genes in the rumen epithelium during grain-induced ruminal acidosis in lactating dairy cattle. A total of 16 rumen-fistulated, lactating Holstein dairy cattle (618±35 kg of body weight, 221±32 days in milk) were used in a randomized complete block design study. All cattle were … …American Journal of Animal and Veterinary Sciences, Vol. 7, Issue 3 · 19 Sep 2012 · 8,035 accessesView PDF Cite

Research ArticleOpen accessAdaptation to High Grain Diets Proceeds Through Minimal Immune System Stimulation and Differences in Extracellular Matrix Protein Expression in A Model of Subacute Ruminal Acidosis in Non-lactating Dairy CowsB. W. McBride, O. AlZahal, M. A. Steele, L. DionissopoulosProblem statement: Subacute Ruminal Acidosis (SARA) is a metabolic disorder affecting approximately 20% of all dairy cattle in North America. Although the presence of SARA has been described for some time, the etiology of the disorder remains uncertain. For example, many animals diagnosed with SARA seem to remodel and adapt their epithelium to accommodate the stresses imposed by SARA, but … …American Journal of Animal and Veterinary Sciences, Vol. 7, Issue 2 · 25 Jul 2012 · 8,118 accessesView PDF Cite
