toxémie de gestation de la vache

CONT: Pregnancy toxemia in cows is similar to the condition in small ruminants and is the result of fetal carbohydrate or energy demand exceeding maternal supply during the last trimester of pregnancy. It is precipitated by large or multiple fetuses, feed low in energy or protein, and health conditions that increase energy demand or decrease ability to take in nourishment (e.g., lameness and oral diseases).

OBS: Las vacas en balance energético negativo movilizan reservas corporales generando acetil Co A [coenzima A]. El acetil Co A se transforma en cuerpos cetónicos debido a la falta de metabolitos intermedios en el ciclo de los ácidos tricarboxílicos.
