Ruminal pH regulation and nutritional consequences of low pH

Animal Feed Science and Technology, 2012
Volatile fatty acids (VFA) and lactic acid can build up in the rumen and reduce ruminal pH. Low ruminal pH for prolonged periods each day can affect feed intake, microbial metabolism and feed digestion, and has also been related to inflammation, diarrhea

Blood gas analyses, ruminal and blood pH, urine and faecal pH in dairy cows during subacute ruminal acidosis

Comparative Clinical Pathology, 2009
The aim of this study was to investigate the variations of some physiological parameters in dairy cows during subacute ruminal acidosis (SARA), a common important disorder of dairy cows that occurs in early lactation.

Comparison of Rumen Fluid pH by Continuous Telemetry System and Bench pH Meter in Sheep with Different Ranges of Ruminal pH [PDF]

The Scientific World Journal, 2014
We aimed to compare the measurements of sheep ruminal pH using a continuous telemetry system or a bench pH meter using sheep with different degrees of ruminal pH.

Methods of Evaluating Ruminal pH in Dairy Cattle

American Association of Bovine Practitioners Conference Proceedings, 1998
Progress in understanding ruminal acidosis in dairy cattle has been limited by the methods available for determining ruminal pH. We evaluated three different methods of measuring ruminal pH in 8 ruminally-cannulated Holstein cows in early lactation as ...

Correlation between ruminal pH and body condition score in cows with subacute ruminal acidosis

Revista MVZ Córdoba, 2017
Objective. The purposes of this field study were to a) confirm the presence of subacute ruminal acidosis (SARA) in Turkish dairy herds in Aydin region, b) record its regional distribution and c) to determine whether there is a relationship between body ...

Effects of oregano essential oil on the ruminal pH and microbial population of sheep.

PLoS ONE, 2019
Oregano essential oil (OEO), which has antimicrobial properties, may be used for altering the ruminal pH and microbial populations of sheep, as observed by the altered volatile fatty acid patterns.

The effect of pH on ruminal methanogenesis [PDF]

FEMS Microbiology Ecology, 1996
When a fistulated cow was fed an all forage diet, ruminal pH remained more or less constant (6.7 to 6.9). The ruminal pH of a concentrate-fed cow decreased dramatically in the period soon after feeding, and the pH was as low as 5.45. Mixed ruminal bacteria from the forage-fed cow converted CO2 and H2 to methane, but the ruminal fluid from the ...

Factors associated with ruminal pH at herd level [PDF]

Journal of Dairy Science, 2012
The objective of this study was to evaluate factors associated with ruminal pH at herd level. Four hundred and thirty-two cows of a Thuringian dairy herd were sampled before claw trimming using a rumen fluid scoop. Volume and pH of the rumen sample were measured, and lactation number, percentage of concentrates in the ration, days in milk (DIM), time ...

Effects of induced subacute ruminal acidosis on milk fat content and milk fatty acid profile [PDF]

, 2008
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
