Multiple effects of preeclampsia in cows on postnatal growth and health of offspring

Scientific interest in such pathologies of pregnancy as functional deficiency of the fetoplacental system, intrauterine growth retardation of embryo and fetus, and preeclampsia (gestosis), is caused not only by their wide spread among productive animals, but also by negative impact on postnatal growth and the health of offspring. The influence of a preeclampsia on incidence of newborn calves of anemia, an omphalitis, inflammatory diseases of gastrointestinal and respiratory tracts and also intensity of growth in the first two months of life was studied on red-motley cows in 2016 in the conditions of a large dairy complex (Voronezhpishcheprodukt Co Ltd, Novousmansky Rregion, Voronezh Province).

The cows were assessed for clinical signs of preeclampsia (pathological swelling of mammary gland, ventral abdominal wall, dewlap, pelvic extremities, arterial hypertension and proteinuria), the blood concentrations of progesterone, estradiol and dehydroepiandrosterone sulfate (DHEA-S) were determined, the endogenous intoxication features were examined, i...
