title: [Biological and biochemical studies of the sperm and blood serum of rams with degraded sperm production].
abstract: Experiments were carried out with 27 rams with impaired semen production, belonging to SIBT (11), Hampshire (5), Il-de-France (11) quality indices being tested in 80 ejaculates and in as many samples of blood serum. The semen was investigated in terms of ejaculate volume and motility and concentration of spermatozoa. The pathologic forms observed were classified as primary, secondary, and tertiary. Besides, the content was investigated of citric acid, fructose, and protein polymorphism of semen plasma and blood serum. It was found that ram semen of low spermatozoa motility the percent of abnormal forms was essentially high, and deteriorated semen production was associated with higher citric acid content. The level of the individual protein fractions in the semen plasma and the blood serum in test rams varied within a wide range, and was not related to the quality of their semen production.
