Supplementing the diet with gluconeogenetic precursors in dairy cows is a commonly used practice to alleviate energy deficiency and to prevent or treat some metabolic disorders, like fatty liver or ketosis. Due to their rapid and efficient absorption and their property to increase the glucose supply as precursors for gluconeogenesis, the most commonly used materials are propylene glycol, glycerol and propionates. However, beside the method and period of supplementation, the energetic condition of the animals alters also their effectiveness. The aim of the authors was to review the literature on the effect of the most frequently used gluconeogenic precursors on milk yield and milk components, on energetic profile and some reproductive parameters.
