Data of "Accuracy of predicting chemical body composition of growing pigs by dual-energy X-ray absorptiometry"

Data set for article "Accuracy of predicting chemical body composition of growing pigs by dual-energy X-ray absorptiometry" (DOI). Data set of Swiss Large White entire male pigs for nutrient composition (water, lipid, N, ash, Ca and P) determined by wet-chemistry and body composition (lean mass, body mineral content and fat tissue mass) by dual-energy X-ray absorptiometry (DXA) in the empty body of live pigs and (N=61) in pig carcasses (N=68) within a body weight range from 20 to 100 kg. metadata.xlsx: description of variables in the data sets emptybody.txt: corresponds to contents of the empty body at slaughter (three days after DXA live scans) and DXA live scans Carcass.txt: corresponds to carcass contents and DXA carcass scans on the day of slaughter本数据集对应论文《基于双能X射线吸收法（dual-energy X-ray absorptiometry, DXA）预测生长猪体化学组成的准确性》（DOI）。该数据集以体重介于20~100kg的瑞士大白猪（Swiss Large White）整雄猪为研究对象，通过湿化学法（wet-chemistry）测定其营养组成（包括水分、脂质、氮（N）、灰分、钙（Ca）及磷（P）），并采用双能X射线吸收法测定其空体成分（瘦体重、体矿物质含量及脂肪组织量）：其中活猪空体样本量为61（N=61），胴体样本量为68（N=68）。 metadata.xlsx：用于说明数据集中各变量的详细定义 emptybody.txt：对应活猪双能X射线吸收法活扫描数据，以及活猪接受该扫描后三日屠宰所得的空体成分数据 Carcass.txt：对应屠宰当日的胴体成分数据以及双能X射线吸收法胴体扫描数据
