Efficiency of "Kexxtone" drug for bovine ketosis preventive in the first trimester lactation to improve the immunity of newborn calves

Modern stage of dairy cattle husbandry development requires multifaceted approach to animal upkeep on dairy farms, including not only hygiene and feeding but also preventive treatment of various visceral diseases. Ketosis is one of the most common non-communicable disease attributable to high yielding cattle. Ketosis usually causes several negative consequences. The most important ones are: yield reduction, lower body resistance, exhaustion, prolonged recovery period after calving, quality of colostrum is poor (the content of immunoglobulins is low), morbidity and mortality of calves in the neonatal period are large. That leads to a higher cull rate, reduced operational life span (around 2-3 lactations), and reduced amount of expected offspring. Kexxtone boluses administration during gestation period has been registered to have a positive effect on cow health condition during lactation period. The amount of ketone bodies in blood does not exceed the amount of ketone bodies in blood of healthy animals. That indicates normalization of energy balance after calving.
