Also known as: Febra de lapte
Febra de lapte este o tulburare metabolică acută a vacilor de lapte în jurul fătării, cauzată de o scădere bruscă a calciului sangvin la începutul lactației. Afectează de obicei vacile în vârstă, cu producție ridicată, în una-două zile de la fătare. Calciul scăzut provoacă slăbiciune musculară, decubit și, netratat, colaps circulator și moarte.
Milk fever (parturient hypocalcemia) is a common periparturient metabolic disease of dairy cattle. Despite the name, there is no fever; the problem is acutely low blood calcium.
The sudden calcium demand of colostrum and milk production at calving outstrips the cow's ability to mobilize calcium. Risk rises with age, high yield, and high-calcium dry-cow diets.
Early excitement and muscle tremor give way to weakness, a cold and dry muzzle, an S-shaped neck, sternal then lateral recumbency, bloat, and eventually coma. Calving difficulty and retained placenta may accompany it.
Clinical signs near calving and response to calcium therapy; confirmed by low serum calcium.
Intravenous calcium given slowly with cardiac monitoring produces rapid recovery; oral calcium supports milder cases.
Low-calcium or anionic (DCAD) dry-cow diets, adequate magnesium, and oral calcium at calving for high-risk cows.
