Abstract
    The studies were performed on ram semen, harvested in the secondary breeding season. Aries studied in the secondary breeding season were given the preparation ZooBioR¹-1 (BioR 0.5%, Zn 2.5 mg / g, Se 25 mcg / g) and ZooBioR¹-2 (BioR 0.5%, spirulina extract 10 mg / g, Zn 2.5 mg / g, Se 25 mg / g) of 5 g head / day for a period of 50 days. The following parameters were analyzed: testosterone dynamics, ejaculate volume, sperm concentration and number in the ejaculate, sperm mobility. Investigations into the influence of ZooBioR-1 and ZooBioR-2 showed a statistically significant influence on the increase in testosterone levels at the end of the experiment in the experimental groups compared to the control group (P≤0.1). Increased testosterone levels led to increased sexual activity in rams in the secondary season. The preparations had a positive influence on the spermogram indices in rams in the experimental groups at the end of the experiment in the secondary season, compared to the control group. Ejaculate volume increased statistically significantly in the experimental groups (P≤0.001), sperm concentration in the ejaculate increased insignificantly and mobility increased statistically significantly (P≤0.1) in the first experimental group at the end of the experiment the other sperm indexes had oscillations towards the minimum limit and the maximum limit of the followed indices, the data being statistically insignificant.
