The techniques involved in searching for bovine milk protein variants by the direct sequencing of genes are discussed. Examples are drawn from our studies of two major milk protein genes, b-lactoglobulin and aS1-casein. In the former case it was possible to subdivide the A and B variants even further according to point mutations found in the promoter region of the gene, while in the latter case, a New Zealand aS1 casein type A variant in Friesians was shown to arise from a point deletion in the gene which differs significantly from a mutation reported to give rise to the same type A variants in the German Red breed. The potential of this analytical approach for analysing milk protein genes is discussed.
