| 摘 要： | 为研究贵州香猪生长的钙、磷需要量,选择60～75日龄贵州从江香猪34头(公母各半),采用扣除蛋白质等消化能(DEpf)饲粮设计和比较屠宰试验,测定贵州香猪生长的钙、磷沉积规律。结果表明,贵州香猪每千克自然增重的净钙需要量为10.03-0.184 BW(g),净磷需要为3.46-0.000 4 BW(g)。

| Abstract: | An experiment on the deposit regularities of calcium and phosphorus for growth were carried out with 34 same genetic background Congjiang Xiang piglets at the age of 60 to 75 days by using of protein-free equalized digestible energy（DEpf） diet design and comparative slaughter methods to ascertain the requirements of calcium and phosphorus for growth of Guizhou Xiang pigs.The results indicate that requirements of net calcium and net phosphorus for growth were 10.03~0.184 BW g/kg and 3.46~0.000 4 BW g/kg of live body weight gain,respectively. |
