Abstract: | The serum albumin genotypes of 65 Jersey × Hariana (F1), 75 Holstein Friesian × Hariana (F1) and 47 Brown Swiss × Hariana (F1) crossbred cows were determined by starch gel electrophoresis. Two albumin alleles AlbF and Albs , but only either as AlbF homozygotes or AlbFs heterozygotes, were observed amongst these animals. There were no AlbS 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 AlbF allele was associated with increased milk yield and greater birth weights. |
