Ultrasound diagnosis of pregnancy, monitoring of mares' physiological state

The results of complete evaluation of the mare keeping system at the Hartley Horse House' breeding center, Moscow Region, the monitoring of their condition after insemination and the diagnosis by ultrasound of gestation are presented. The animals are kept in good sanitary and hygienic conditions: indoor air temperature is 4-5 °C, relative air humidity - 75 %, air movement speed - 0.3 m/s, the illumination - 150 LX. The quality of the feed according to the main parameters corresponds to the average standard with the exception of slightly increased fiber content. As a result of blood tests on pregnant mares an increase in the number of eosinophils has been found, - on average in the group - 7 ± 1.85 % and slight decrease in segmented neutrophil index - on average in the group - 39 ± 2.21 %. All biochemical parameters of the blood serum of the mares in the first gestation period are in accordance with physiological norms, except for an increase in the level of alkaline phosphatase in the blood serum - 417...
