title: [Biochemical and hematological changes in sows during estrus].
abstract: After the second and fourth parturition of piglets, ten clinically healthy sows, weaned on the second day of life, were subjected to examination two to three days before heat, during heat (defined by typical changes on the outer genitals and immobilization in the presence of a boar) and two days after insemination. During the morning hours, four hours after the last feeding, blood was taken from V. cava cranialis. Seventeen parameters were determined in whole blood and in the blood serum. In the period of oestrus, compared with the period two to three days before this period and two days after insemination, a marked increase was observed in the concentration of the serum levels of 11-hydroxycorticosteroids, iron, and in the activity of alanine aminotransferase. The activity of aspartate aminotransferase was increased in heat only in comparison with the period of the two days after insemination. The concentration of haemaglobin in whole blood was significantly increased in comparison with the period before oestrus and after insemination. Further, in the heat period -- as compared with the time before it -- a considerable drop was observed in the content of inorganic phosphorus and vitamin A. The possible mechanism of the occurrence of other changes is discussed.
