Oral Nicotinic Acid as a Treatment for Ketosis

Abstract

Changes in blood metabolites and milk production were measured in eight cows with subclinical or clinical ketosis following treatment with daily doses of 12 g nicotinic acid fed with the concentrate mixture. Ketotic cows displayed a positive milk ketone test, reduced milk production and feed intake, hypoglycemia, hyperketonemia, and elevated free fatty acids in plasma. The milk ketone test was negative in all cows 5 to 9 days following initiation of treatment. After 7 days of treatment, milk production and glucose in plasma were increased while there were decreases in plasma β-hydroxybutyrate and free fatty acids. No relapses occurred. © 1979, American Dairy Science Association. All rights reserved.
