Summary A new asi‐casein variant (α S1 ‐CN F) with a frequency of 0.009 was demonstrated in a genetic resource of German Black and White Cattle by isoelectric focusing in polyacrylamide gels and by polyacrylamide gel electrophoresis under alkaline conditions. α s1 ‐CN F was not present either in German Holstein Friesians, which originate from crossing Holstein Friesians with German Black and White Cattle, or in milk samples from eight other breeds in Germany.
