Summary The serum albumin genotypes of 65 Jersey × Hariana (F 1 ), 75 Holstein Friesian × Hariana (F 1 ) and 47 Brown Swiss × Hariana (F 1 ) crossbred cows were determined by starch gel electrophoresis. Two albumin alleles Alb F and Alb s , but only either as Alb F homozygotes or Alb Fs heterozygotes, were observed amongst these animals. There were no Alb S homozygotes or other genotypes. Highly significant relationships between albumin genotypes and both birth weights and first‐lactation milk yields of these cows were observed. The Alb F allele was associated with increased milk yield and greater birth weights.
