title: [The effect of apramycin on bacterial contamination and the survival of boar semen during a short preservation period].
abstract: 264 ejaculate samples taken from seven boars were tested for the bacteriostatic action of apramycin and for its effect on some sperm quality parameters during 96-hour storage. Apralan soluble powder, produced by Elanco Products Limited, was used in the trials at the concentrations of 2.5 to 500 mg per 1000 ml of diluent. The preparation was evaluated according to sperm motility during storage, according to the concentration pattern of hydrogen ions, morphological changes in spermatozoa, thermoresistance test, bacteriological tests and other examinations. The concentrations of 200 to 250 mg of apramycin in combination with 500 000 i. u. of G-penicillin potassium salt had a statistically significantly more favourable effect on the survival of boar sperm, as compared with the combination of streptomycin with penicillin.
