[Effect of various solvents and temperatures on the survival of boar spermatozoa]

The second fraction of boar ejaculate was thinned with six differently treated diluents of the Beltsville 3 type and with four diluents of the Ejadyl type containing Chelaton 3. All thinned sperm was kept at the temperature of +4 degrees C and +16 degrees C for 72 hours. At both test temperatures throughout the period of storage, diluents no. 4 and 9 (Beltsville type) and no. 8 (Ejadyl type) were found to be the best. No statistically significant difference was revealed between the mentioned diluents as to their effect. After 72 hours, progressive movement was observed, on an average, in more than 50% of spermatozoa in samples with the mentioned diluents.
