Abstract

This experiment was conducted to study the effects of different inorganic phosphorus sources on apparent digestibility and metabolism of calcium and phosphorus of weaned piglets. Two hundred weaned piglets at the age of (28±2) days with similar genetic background, good health status and body weight of (8.41±0.97) kg were randomly divided into 5 groups with 4 replicates of 10 piglets (half male and half female) per replicate. The piglets in the 5 groups were fed diets supplemented with 0.66% powdery dibasic calcium phosphate (DCP), 0.44% powdery mono-calcium phosphate (MCP), 0.44% granular MCP, 0.49% powdery mono-calcium and di-calcium phosphate (MDCP) or 0.49% granular MDCP, respectively. Five group diets keep a same level of calcium and phosphorus. The whole experiment lasted for 28 days. The results showed as follows:1) the apparent digestibility of calcium and the dry matter had no significant difference among groups (P>0.05). The apparent digestibility of phosphorus of powdery MDCP group was significantly higher than that of powdery DCP, powdery MCP and granular MCP groups (P<0.05), but no significant difference was found between powdery MDCP and granular MDCP groups (P>0.05). 2) There were no significant differences in the contents of serum calcium and phosphorus among groups (P>0.05). But compared with the other groups, the serum alkaline phosphatase activity of powdery MCP group was significantly reduced (P<0.05). 3) There were no significant differences in the coffin bone weight, coffin bone ash weight, coffin bone ash ratio and coffin bone phosphorus content among groups (P>0.05). However, the coffin bone calcium content of powdery MDCP, powdery MCP and granular MCP groups was significantly higher than that of powdery DCP group (P<0.05). In conclusion, compares with powdery DCP, powdery MDCP, powdery MCP, granular MDCP and granular MCP can improve the metabolism and utilization of calcium and phosphorus, all of them are good inorganic phosphorus sources to substitute powdery DCP.
