Characterization of ruminal temperature and its relationship with ruminal pH in beef heifers fed growing and finishing diets.
This study characterized the relationship between ruminal temperature (T rum) and pH in beef cattle fed growing and finishing diets. In Exp. 1, 16 ruminally cannulated beef heifers (388.5 ± 34.9 kg BW) were fed 4 growing diets in a replicated 4 × 4 Latin square with four 21-d periods. Diets were (DM basis) grower control (CTLg; 35% barley grain plus 5% canola meal), 40% corn dried distillers gr...
متن کاملEffects of a bacterial probiotic on ruminal pH and volatile fatty acids during subacute ruminal acidosis (SARA) in cattle
Effects of a bacterial probiotic (BP) on ruminal fermentation and plasma metabolites were evaluated in four Holstein cattle (body weight, 645 ± 62 kg; mean ± SD) with induced subacute ruminal acidosis (SARA). SARA was induced by feeding a SARA-inducing diet, and thereafter, 20, 50 or 100 g per head of a commercial BP was administered for 7 consecutive days during the morning feeding. Cattle wit...
متن کاملECG Changes in Acute Experimental Ruminal Lactic Acidosis in Sheep
For induction of ruminal acidosis, 10 clinically healthy three years old non pregnant female sheep were selected. Prior to the infusion of sucrose (0 hour), rumen and blood samples were obtained in order to determine baseline rumen and blood pH, respectively. Electrocardiogram (ECG) was also recorded. Acute ruminal acidosis was induced experimentally with sucrose at a dose of 18g kg-1 body weig...
متن کاملSubacute Ruminal Acidosis in Dairy Cattle
Ruminal acidosis is the consequence of feeding high grain diets to ruminant animals, which are adapted to digest and metabolize predominantly forage diets. Feeding diets that are progressively higher in grain tends to increase milk production, even in diets containing up to 75% concentrates. However, short-term gains in milk production are often substantially or completely negated by long term ...
متن کاملEffect of a low-moisture buffer block on ruminal pH in lactating dairy cattle induced with subacute ruminal acidosis.
The objective of this study was to evaluate the effect of a low-moisture buffer block on ruminal pH and milk production in cows induced with subacute ruminal acidosis (SARA). Sixteen ruminally cannulated cows were randomly assigned to treatment (access to buffer blocks) or control (no buffer blocks). Ruminal pH was recorded each minute; dry matter intake (DMI), milk yield, and milk composition ...
