The study addressed the importance of yeast (Saccharomyces cerevisiae) viability for reducing the incidence of subacute ruminal acidosis (SARA) and improving total tract nutrient digestibility in beef heifers. Six ruminally cannulated beef heifers (680 ± 50 kg BW) were used in a replicated 3 × 3 Latin square design and were fed a diet consisting of 40% barley silage, 10% chopped grass hay, and ...

Two lactating dairy cows fitted with a rumen cannula received successively diets containing 0%, 20%, 34% and again 0% of wheat on a dry matter basis. After 5, 10 and 11 days, ruminal pH was measured between 8:00 and 16:00 hours, and milk was analysed for fat content and fatty acid profile. Diets with 20% and 34% wheat induced a marginal and a severe subacute ruminal acidosis respectively. After...

The aim of this study was to confirm the hypothesis that artificial brushes administered rumen can partially replace function structural fibre, and increase milk production or quality. To mitigate risks feeding low levels physically effective neutral detergent fibre (peNDF) cattle, administration ruminal mechanical stimulating (RMS) examined in 22 high-yielding lactating Holstein dairy cows. co...

distal renal tubular acidosis is a syndrome of abnormal urine acidification and is characterized by hyperchloremic metabolic acidosis, hypokalemia, hypercalciurea, nephrocalcinosis and nephrolithiasis. despite the presence of persistent hypokalemia, acute muscular paralysis is rarely encountered in males.here, we will report an eighteen year old male patient who presented with flaccid quadripar...

Abstract Sub-Acute Ruminal Acidosis (SARA) is a metabolic disorder in dairy cattle characterized by lowered ruminal pH, as result of high grain diets. Dairy cows experiencing SARA show decreased milk production and impaired health; thus, has major economic impacts. been associated with changes the rumen epithelial microbiota. Previously, we performed meta-transcriptome sequencing on biopsy samp...

Subacute ruminal acidosis (SARA) negatively impacts the dairy industry by decreasing dry matter intake, milk production, profitability, and increasing culling rate and death loss. Six ruminally cannulated, lactating Holstein cows were used in a replicated incomplete Latin square design to determine the effects of SARA induction on the ruminal microbiome and epithelium. Experimental periods were...
