The effects of supplemental niacin and methionine on serum glucose, betahydroxybutyric acid, and non-esterified fatty acid levels during late gestation and early postpartum period in Damascus dairy goat

Abstract

The objective of this study was to assess the changes in serum glucose, beta-hydroxybutyric acid ß-HBA , and nonesterified fatty acid NEFA levels in Damascus dairy goats fed niacin Nia and methionine Met during late gestation and early postpartum period. A total of 75 dairy goats at 105th day of gestation were divided into 3 groups as control no supplementation , Nia 20 g/kg Nia , and Met 2.5 g/kg Met groups. The dietary treatments continued until parturition. Dairy goats fed dietary Nia had greater serum glucose levels on day 125 of gestation compared to the other dietary treatments P
