The contents of histidine dipeptides, a metabolic products of muscle protein, were investigated to compare muscle composition among the 9 domestic animals including cattle. In major domestic animal, analyzed the effects of age, part and sex of the animals on their muscle composition. Large amounts of carnosine(68.63+_17.41 micro mol/g) were detected in cattle and it was higher than other animals. Wheres the content of anserine showed high level in order of turkey, chickens and duck. The ratio of carnosine and anserine(C/A ratio) was different depending on the animal species. Statistical data indicated that difference among species was significant(p0.05). The contents of histidine dipeptides in hearted muscle by boiling for 40 minutes at 110 degrees centigrade was similar to those of raw muscle. C/A ration in heated muscle was not different from that of raw muscle, indicating that no change has been made after heating process. The contents of camosine and anserine were different according to the parts of their muscle. Especially chuck of the mammalian showed extremely low level of histidine dipeptides compared with other parts, while C/A ratio maintained certain level regardless of age, part, sex. Therefore, based on the content of histidine depeptides, could be found the difference of muscle composition among the species. Also C/A ratio of horse, pig, cattle, duck, sheep nd turkey were characteristic respectively.
