Tim W Clark, Mark R Stromberg, and R Lee Rayburn, Black-footed ferret prey requirements: an energy balance estimate: .


A model based on calculations of metabolizable energy requirements estimated the annual prey requirements for 1 reproductive female black-footed ferret (Mustela nigripes) and her young. Both whitetailed and black-tailed prairie dogs (Cynomys leucurus and C. ludovicianus) were considered as prey. Gestation, lactation, and ferret pup growth were modeled. A general regression of mustelid prey biomass requirements helped verify metabolizable energy calculations. Populations of between 474 and 1,421 blacktailed prairie dogs and between 412 and 1,236 white-tailed prairie dogs are predicted as necessary to sustain the annual predation by the female and young ferrets. Minimum ferret densities expected to occur and sizes of ferret preserve [...]
