Abstract
Obtaining viable posterity is one of the urgent problems of production. The research results indicate that in the state of hypoxia up to 30–37 % of the calves and 20–25 % of pigs are born and 90 % of them die in the first hours or days after birth. However, of the known literary sources, the influence of hypoxia on oxygen homeostasis and acid-base balance of the fetus and newborn animals are not very clear. In the article the research results of oxygen homeostasis and acid-base balance indicators of the fetus and newborn animals are presented. It is established that depending on the degree of hypoxia action during the prenatal growth and development calves are born in a state of mild (adequate spontaneous respiratory movements), medium (inadequate spontaneous respiratory movements after birth) and severe hypoxia (animals are born with no signs of respiratory or meconium in the amniotic fluid), and pigs in a state of severe hypoxia. Effect of hypoxia on the fetus causes a decrease of blood pH in newborn animals that is accompanied with 1.66 times increased content of hydrogen ions in the blood. Acidotic shift in organism of animals born in a state of hypoxia is accompanied by hypoxia and hypercapnia, 1.35–1.25 times (P<0.01) decreased partial pressure of oxygen, 1.56–1.37 times (P<0.01) increased partial pressure of carbon dioxide. On average, the supply of tissues with oxygen in calves of experimental groups were 1.25 times less than in clinically healthy calves (P<0.01). The greatest number of dead piglets and piglets in a state of hypoxia is born in the third part of the generative process. Acidotic shift in the body of the fetus and newborn animals of the experimental group is characterized by increased anaerobic glycolysis, a decrease the content of bases in the blood (P<0.01).
