Influence Of Diets Formulated To Increase The Supply Of Ketones Or Ketone Precursors On The Carbohydrate Status And Performance Of Transition Dairy Cows, Jeffrey Michael Defrain
Influence Of Diets Formulated To Increase The Supply Of Ketones Or Ketone Precursors On The Carbohydrate Status And Performance Of Transition Dairy Cows, Jeffrey Michael Defrain
Electronic Theses and Dissertations
Research to date has focused on increasing the supply of glucose precursors in transition dairy cows to reduce ketosis. Ketones and ketone bodies represent energy sources for body tissues; therefore, conserving blood glucose for lactose synthesis in the mammary gland. This led to the hypothesis that transition cows might benefit from diets formulated to stimulate rumen epithelial ketogenesis or dietary ingredients supplying ketone precursors. A series of experiments were conducted to study the impact of diets formulated to increase the supply of ketones (via feeding lactose, glycerol, or an alphaamylase enzyme preparation) or ketone precursors (feeding Ca soaps of longchain …
