Abstract

Assessing body or carcass composition in growing pigs is essential to refine nutritional models, select for specific traits and evaluate pork products. The gold standard methods are dissection and chemical measurements, which are time-consuming and invasive ways to obtain the data. Different teams have tested dual-energy x-ray absorptiometry (DEXA), especially for determining total and regional body composition of fat, soft lean tissues and bone minerals [1-3]. The DEXA measurements are quick, noninvasive, precise, and operator independent. However, the Open Access

准确预测猪的各种体重的化学成分:不再是神话!
评估生长猪的身体或胴体组成对于完善营养模型、选择特定性状和评估猪肉产品至关重要。金标准方法是解剖和化学测量,这是耗时和侵入性的方法来获得数据。不同的团队已经测试了双能x射线吸收仪(DEXA),特别是用于确定脂肪、软瘦组织和骨矿物质的总体和局部身体组成[1-3]。DEXA测量具有快速、无创、精确、独立于操作人员的特点。然而,开放获取
