1.Broiler
MCP seems to have the highest P digestibility compared with other feed Phosphorus. The results confirm that the P digestibility of MCP is 19%,25%,25%higher than DCP respectively. According to the P digestibility of MCP and DCP, we can conclude that 1-kilogram DCP=0.6 kilogram MCP. We could determine which feed phosphorus to use according to the price of corrected P. The broilers which feed MCP grow faster than the broilers that feed DCP.
2.Laying hens
The results confirmed that there is great variation in P relative biological value between feed phosphates, and the P relative biological value of laying hens is different from the index of performance. The effect of different feed phosphates applying in laying hens is that MDCP and DCP are the best of all the 4 tested sources, and the effect of MCP is better than MSP. So MDCP and DCP are the best sources of P for laying hens, but MCP is not fit for laying hens. And the granular DCP is better than other feed phosphates.
3.Pigs
The relative biological value of MCP is 18% higher than DCP in piglets. And the effect of MCP and DCP is that MCP 0.65 kilogram can take place of 1-kilogram DCP in piglets’ feed. We could determine which feed phosphorus to use according to the price of corrected P of all tested sources. The prevenient results showed that when MCP takes place of DCP in piglets’ feed, and the feed intake could improve by 16%, the average daily gain could improve 11%, and the profit could improve 40%.
4.Fish
The best of all tested feed phosphorus is MCP for fish. And the level of Non-phytate P in carp is 0.60% usually. If we add MKP in the carp’s feed, the optimum quantity is 20.2kilogram per ton.
