The invention provides a Sichuan white rabbit living body breed conservation method, and belongs to the field of genetic resource conservation of livestock. The breed conservation method comprises the steps of breeding rabbit collecting, population building, breed conservation core group number setting, breed conservation selective breeding and breed reserving, inbreeding coefficient increment controlling and generation interval prolonging. According to the method, Sichuan white rabbit genetic resource collecting is conducted in different villages and towns of an original Sichuan white rabbit production area, a breed conservation area stock seed farm is established in a core region of the original production area, therefore, artificial breeding is closer to an original habitat, living body conservation of Sichuan white rabbit genetic resources is conducted, and the relatively stable biological characteristics of the Sichuan white rabbit genetic resources are kept; the core breed conservation population number is set as 360 or above, the family number is set as 6 or above, the male-female ratio ranges from 1:4 to 1:6, and the effective content of a breed conservation group and the breed conservation economic cost are both taken into account; the Sichuan white rabbit generation interval is prolonged, generation updating is conducted once every 2-3 years, therefore, the variety change speed is decreased by reducing Sichuan white rabbit group turnover, the breed conservation group number is relatively decreased, and the breed conservation economic cost is reduced.
