Ovine pregnancy toxaemia (OPT) is a metabolic disorder that is associated with a negative energy balance in the last six weeks of pregnancy. The disease is common in sheep flocks. It affects mostly pregnant ewes with multiple foetuses. Our aim was to investigate actuality of OPT and to find out the most effective prophylaxis against it in sheep flock. There were assessed the general health, bodyweight (BW), body condition (BC), blood morphology, chemistry, and ultrasound (US) examination for two times – in the middle and end of gestation. Blood morphology, rectal temperature changes are not helpful indicators for diagnosis of OPT (p is greater than 0.05). It is helpful to carry out US for detecting predisposed to OPT sheep. Level of alkaline phosphatase, triglycerides and cholesterol were significantly increased at the end of gestation in multiple foetuses ewes (p is less than 0.05). These parameters were higher in the middle of gestation for two and three foetuses ewes in comparison with one foetus ewes (p p is less than 0.05). In conclusion, the express methods concerning glucose level in blood and ketonbodies in urine are not profitable to foresee OPT. It allows detecting already begun disease.
