متن کاملEffects of feeding buffering mineral mixture on subacute rumen acidosis and some production traits in dairy cows.
This trial was designed in order to evaluate the incidence of subacute rumen acidosis (SARA) during early lactation and to investigate the possibilities for its prevention by use of a buffering mineral mixture. On the beginning of the trial it was found that the pH value of rumen fluid in 4 animals was lower than normal (pH < 6.0) and that 20% of animals have had SARA. The control and the exper...
متن کاملUltrasonography of the rumen of dairy cows
BACKGROUND This study describes the ultrasonographic findings of the rumen in 45 healthy dairy cows. RESULTS The cows were scanned on both sides using a 5.0 MHz transducer. The dorsal visible margin of the rumen ran parallel to the lung from cranioventral to caudodorsal. It was furthest from the dorsal midline at the 9th intercostal space (48.3 ± 9.24 cm) and closest at the 12th intercostal s...
متن کاملMechanisms of Acid Absorption in the Rumen and Impacts on Subacute Rumen Acidosis
A distinguishing feature of ruminants is that they rely on anaerobic fermentation of feeds in the rumen and reticulum (collectively termed the reticulo-rumen) to supply metabolizable energy in the form of short-chain fatty acids (SCFA) and metabolizable protein in the form of microbial protein. While the production of SCFA is a nutritionally desired effect, excessive rates of SCFA production an...
متن کاملImpact of Subacute Ruminal Acidosis (SARA) on Ruminal Microbiome, Lipopoly saccharide and Bioamine and Rumen Epithelial Health of Dairy Cows
Maximizing milk yield without impairing host health is a great challenge for dairy industry. However, the high concentrate feeding often unavoidably increases the risk of Subacute ruminal acidosis (SARA) in dairy cows, characterized by periodic episodes of low ruminal pH. The economic costs caused by SARA are enormous, while its pathogenesis is not very clear. As the first and the main digestiv...
