Female pigs aged between one day (body weight 1.39 +/- 0.20 kg) and 1123 days (b. w. 233 +/- 32 kg) were allotted to 10 groups of various age and analyses of the concentration of DNA, RNA and protein in 9 different tissues were performed. The wet weight: DNA-, the protein: DNA- and the RNA: DNA-ratio were determined. With the exception of the liver the content in DNA, RNA and protein increased to the age of 1123 days. The highest fresh weight: DNA ratio of 2041 was reached on the 1123rd day in the M.longissimus; the smallest (111) existed at this time in the spleen. In the liver the highest content in fresh weight, in DNA and RNA was found on the 180th day. The smallest increases in the content of DNA and RNA in the mentioned period were in the brain, the highest in the spleen, the liver and the M.longissimus dorsi. The values can be used as a basis for studies on the influence of feeding and of diseases (infections) on growth.
选取年龄在1日龄(体重1.39±0.20千克)至1123日龄(体重233±32千克)之间的雌性猪,将其分为10组,每组年龄不同,并对9种不同组织中的DNA、RNA和蛋白质浓度进行分析。测定了湿重与DNA的比值、蛋白质与DNA的比值以及RNA与DNA的比值。除肝脏外,DNA、RNA和蛋白质的含量在1123日龄前均有所增加。最长肌在1123日龄时达到最高鲜重与DNA比值2041;此时脾脏的该比值最小(111)。肝脏在180日龄时鲜重、DNA和RNA含量最高。在上述时期,大脑中DNA和RNA含量增加最少,脾脏、肝脏和背最长肌中增加最多。这些数值可作为研究饲养和疾病(感染)对生长影响的基础。
