Abstract: Nineteen BAC clones were identified by hybridization of the bovine genomic BAC library CHORI-240 with mixed CSN1S1- and CSN3-specific probes. Two of the clones were shown to contain the genes CSN1S1, CSN1S2, CSN2, STATH and CSN3, and five were proved to include the genes CSN2, STATH, CSN1S2 and CSN3. These data showed that the BAC contig was established for the whole casein cluster, including all known five genes.

Key words: BAC-libraries, Bos taurus, contig, casein genes.
