Serum of enough application immunity treats dosage contagion, after inject instantly become effective, the effect is good, fast, but because be serum goods, half-life is short, the serum of akin animal, half-life is 3 weeks, the serum of heterogeneous animal, half-life has 2 weeks only, the significant hold time of immune serum has 2~3 week only commonly. Accordingly, must inject for many times, full amount injects, ability obtains ideal result. Prevent to come on immune serum is multi-purpose preparation of blood of horse, ox, horse, Niu Xieqing is right for other animal, also have antigen sex, have the possibility that causes serum disease, accordingly, use immunity serum should notice to prevent to cause serum disease, main measure of precaution is the goods of use extract, need not unqualified product; Additional, do not have the idea of eager for quick success and instant benefit, want to be used according to requirement dosage, dosing cannot pass big.
