[The content of fresh material, DNA and RNA in different tissues of turkeys during growth. 2. Analysis of the myocardium, the liver, the lungs, the kidney, the pancreas, the spleen and the duodenum].

The highest DNA concentration so far recorded from organs of turkey chicken one day after hatching was the lung value of 8.61 +/- 0.20 mg/g of fresh matter, while the lowest level amounted to 1.92 +/- 0.11 mg/g and was linked to the myocardium. DNA concentrations in the spleen went up from 5.93 +/- 0.26 mg/g on the first day to 13.04 +/- 0.93 mg/g on the 224th day. The highest total amount of DNA on the 224th day was 314.6 +/- 30.23 mg/g in the liver. A high RNA concentration on the first day from hatching was 8.74 +/- 0.14 mg/g in the liver and the lowest 2.51 +/- 0.12 mg/g in the myocardium. DNA levels for the whole period under review (first through 224th days) rose by the following factors: 246.3 in the spleen, 87.4 in the pancreas, 76.6 in the liver, 60 in the duodenum, 40.5 in the kidneys, 18 in the lung, and 31.3 in the myocardium. Functional implications relating to DNA, RNA, and protein variations are discussed in some detail.
