If polyamine is caused to be present in the reacting system for the synthesis of nucleic acids to amplify target genes from a sample, the inhibition of the synthesis due to impurities in the sample can be reduced and the target genes can be effectively synthesized.

1. A method of amplifying a target nucleic acid found in animal feces, said method consisting of the steps of:suspending a sample of animal feces in an aqueous solution, thereby forming an animal feces solution; adding an aliquot of said animal feces solution to a solution containing reagents necessary for PCR amplification to form a PCR amplification system comprising a polyamine in an amount of 0.125 nM-4 mM, said reagents comprising said polyamine; and causing PCR to be carried out in said PCR amplification system, whereby the target nucleic acid found in the animal feces is amplified.
