説明
Thirty-one Holstein steers were slaughtered at 0, 3, 6, 9, 12, 15, 18 and 24 months of age to investigate the changes in muscle composition. Five muscles (psoas major, longissimus thoracis, gluteus medius, biceps femoris and supraspinatus) from the left side carcasses were analyzed for moisture, crude fat and crude protein. The moisture content of each muscle was highest at birth, and thereafter decreased linearly with increase of age, although the rates of decrease were not similar among muscles. On a fat free basis, however, the moisture content remained nearly constant after nine months of age. This is accounted for by the fact that the moisture content decreased along with the increase in crude fat content. The crude fat content of each muscle increased markedly with the advancement of age. The fat content of the psoas major muscle increased most among the five muscles and was significantly higher than those of other is at all ages studied. The crude protein content was highest at three and six months of age, and remained fairly constant after nine months of age. But the values were different among muscles.
