Studies were conducted into concentrations of RNA, DNA, and total protein in various skeletal muscles, diaphragm, right and left ventricles as well as in musculature of the oesophagus, stomach, and urinary bladder of 25 normally developed piglets and 24 sprayleg piglets of differentiated body weight (B.W.). DNA concentration was found to be at its highest in piglets of lowest B.W. The Protein: DNA-quotient increased along with growing B.W. The average value of this quotient in the anterior tibial muscle and brachial triceps muscle of sprayleg piglets was lower than that in normally developed piglets. Average values of the RNA:DNA quotients in the brachial triceps muscle, anterior section of the long dorsal muscle, left ventricle, and stomach muscles were also lower in sprayleg piglets. In newborn piglets, DNA concentrations in ventricles as well as in the muscles of the stomach and oesophagus were higher than those recordable from skeletal muscles. Causes of incapability of newborn piglets to stand on their own feet are discussed in some detail. |
