【摘要】 试验选用贵州从江香猪34头,公母各半分为4组,试验前屠宰一公一母做本底值,采用不同能量、蛋白质进食水平进行日粮试验设计,通过饲养试验、比较屠宰试验和实验室分析相结合的方法,对贵州香猪能量、蛋白质（氨基酸）、钙和磷营养需要模型进行了研究。结果表明:（1）贵州从江香猪的能量代谢规律:维持需要:每kg代谢体重为需要代谢能431.7kJ。其与代谢体重的回归关系为:ME（MJ/d）=-0.0939(BW^0.75)³+2.2129(BW^0.75)²-16.29BW^0.75+40.866（R²=0.9382）生长代谢能需要: 7-16kg体重段:ME（MJ/d）=0.432W^0.75+19.75×预期日增重（kg） 16-25kg体重段:ME（MJ/d）=0.432W^0.75+21.94×预期日增重（kg）（2）贵州香猪蛋白质沉积规律:沉积蛋白（g/d）=1.1675(BW^0.75)³+25.735(BW^0.75)²-181BW^0.75+435.62（R²=0.8826）沉积TAA（g/d）=-0.00005ADG³-0.0009ADG²+0.1284ADG-4.7993（R2=0.9629）沉积T-Lys（g/d）=-0.0000233ADG³-0.0009ADG²+0.1284ADG-4.7993（R²=0.9629）（3）贵州香猪钙、磷的沉积规律:沉积Ca（g/d）=0.0016BW³-0.075BW²+1.109BW-3.7929（R²=0.823）沉积P（g/d）=-0.0001BW³+0.0017BW²+0.0791BW-0.3393（R²=0.9469）更多还原

【Abstract】 34 Guizhou Xiang piglets, half male and female （two of which, one male and onefemale, were slaughtered before the growth trial to take a base data）, were put into 4groups, eight piglets a group, to study the requirement model of energy, protein,calcium and phoshorus by conbining with growth trial, comparision abatage trial andlaboratory analysis. The findings indicate that:First, energy metabolism regularity of Guizhou Congjiang Xiang piglet:Maintenance requirement: each kilogram of metabolic weight needs 431.7kJmetabolic energy. The regression relation between maintenance requiement andmetabolic weight is:ME（MJ/d）=-0.0939(BW^0.75)³+2.2129(BW^0.75)²-16.29BW^0.75+40.866（R²=0.9382）Growth metabolic energy requirement:At the body weight is among 7 to 16 kg:ME （MJ/d） =0.432W^0.75+19.75×expecting daily gain （kg）At the body weight is among 16 to 25kg,ME （MJ/d） =0.432W^0.75+21.94×expecting daily gain （kg）Second, protein deposition regularity of Guizhou Congjiang Xiang piglet:Depositonal protein（g/d）=1.1675(BW^0.75)³+25.735(BW^0.75)²-181BW^0.75+435.62（R²=0.8826）Deposirional TAA（g/d）=-0.00005ADG³-0.0009ADG²+0.1284ADG-4.7993（R2=0.9629）Deposirional T-Lys（g/d）=-0.0000233ADG³-0.0009ADG²+0.1284ADG-4.7993（R²=0.9629）Third, calcium and phosphorous’ deposition regularity of Guizhou Congjiang Xiangpiglet:Depositions Ca（g/d）=0.0016BW³-0.075BW²+1.109BW-3.7929（R²=0.823）Depositional P（g/d）=-0.0001BW³+0.0017BW²+0.0791BW-0.3393（R²=0.9469）更多还原
