FIELD: veterinary science, virology. ^ SUBSTANCE: method for evaluation of semen from bull-sires for contamination with cattle infectious rhinotracheitis virus involves taking semen samples, combining semen samples obtained from bull-sire for one month and their analysis as a single sample. The analysis is carried out by method of molecular hybridization. For evaluation of semen from rejected bull-sires the semen samples are taken obtained for all period of their exploitation. Method provides reducing labor intensity and time for analysis and enhanced sensitivity of analysis in assay of semen contamination with indicated virus. ^ EFFECT: improved method for evaluation of semen. ^ 2 cl, 1 tbl, 4 ex |
