TL;DR: Continued research concerning grain processing, dietary cation-anion balance, narrow-spectrum antibiotics, glucose or lactate utilizing microbes, and feeding management (limit or program feeding) should yield new methods for reducing the incidence of acute and chronic acidosis.

Abstract: Acute and chronic acidosis, conditions that follow ingestion of excessive amounts of readily fermented carbohydrate, are prominent production problems for ruminants fed diets rich in concentrate. Often occurring during adaptation to concentrate-rich diets in feedyards, chronic acidosis may continue during the feeding period. With acute acidosis, ruminal acidity and osmolality increase markedly as acids and glucose accumulate; these can damage the ruminal and intestinal wall, decrease blood pH, and cause dehydration that proves fatal. Laminitis, polioencephalomalacia, and liver abscesses often accompany acidosis. Even after animals recover from a bout of acidosis, nutrient absorption may be retarded. With chronic acidosis, feed intake typically is reduced but variable, and performance is depressed, probably due to hypertonicity of digesta. Acidosis control measures include feed additives that inhibit microbial strains that produce lactate, that stimulate activity of lactate-using bacteria or starch-engulfing ruminal protozoa, and that reduce meal size. Inoculation with microbial strains capable of preventing glucose or lactate accumulation or metabolizing lactate at a low pH should help prevent acidosis. Feeding higher amounts of dietary roughage, processing grains less thoroughly, and limiting the quantity of feed should reduce the incidence of acidosis, but these practices often depress performance and economic efficiency. Continued research concerning grain processing, dietary cationanion balance, narrow-spectrum antibiotics, glucose or lactate utilizing microbes, and feeding management (limit or program feeding) should yield new methods for reducing the incidence of acute and chronic acidosis.

Measurement of barley (Hordeum vulgare) feed quality parameters In Sacco and mapping of associated quantitative trait loci (QTL) in Cattle
Peter Gous
- 01 Jan 2009
TL;DR: The research showed that the development of NIR calibrations appropriate for the detection of post-digestion nutrient measurement is essential for its establishment as a rapid, non-destructive feed quality measurement technique.
Intravenous electrolyte solution containing 84 mEq/L of lactate corrects metabolic acidosis in goats
TL;DR: In this article , the authors investigated the alkalinizing potential of an intravenous electrolyte solution formulated with a high concentration of sodium lactate in acidotic goats, and two solutions containing 84 mEq/L of lactate (L84) or bicarbonate (B84) were formulated.

Cattle are more motivated for a high-concentrate diet than Sudan grass hay, despite low reticulorumen pH.

TL;DR: High-concentrate diet motivates cattle more than Sudan grass hay despite low reticulorumen pH. However, TMR is more highly valued than SG.

Preventing in vitro lactate accumulation in ruminal fermentations by inoculation with Megasphaera elsdenii
L. Kung,Aideen O. Hession +1 more
TL;DR: Inoculation with M. elsdenii prevented an accumulation of lactic acid and excessive drop in pH in vitro fermentations containing a mixed culture of ruminal bacteria, buffer, and primarily rapidly degradable substrates and has potential to prevent lactate accumulation in diets containing readily fermentable carbohydrates.

Relationship of acidosis to other feedlot ailments.
TL;DR: It is unlikely that ruminal histamine causes laminitis, but immunizing cattle against liver abscesses may be possible because hair ingested during grooming may penetrate the rumen wall and aid in this passage.

Predisposing factors of laminitis in cattle
J.J. Vermunt,Paul R. Greenough +1 more
TL;DR: The cause of laminitis should be considered as a combination of predisposing factors leading to vascular reactivity and inhibition of normal horn synthesis, and nutrition, disease, management and behaviour appear to be closely involved in the pathogenesis of bovine laminationitis.
