Age-Dependent Changes in Sperm Production, Semen Quality, and Testicular Volume in the Black-Footed Ferret (Mustela nigripes)1

Abstract: The black-footed ferret (Mustela nigripes), which was extirpated from its native North American prairie habitat during the 1980s, is being reintroduced to the wild because of a successful captive-breeding program. To enhance propagation, the reproductive biology of this endangered species is being studied intensively. The typical life span of the black-footed ferret is approximately 7 yr. Female fecundity declines after 3 yr of age, but the influence of age on male reproduction is unknown. In this study, testi… Show more

“…Thus, it was realized that (1) many males were not breeding naturally and (2) a valuable founder descendant was under-represented. A more detailed assessment of the first challenge revealed a high incidence of sexual incompatibility between designated mates, largely due to improper copulatory positioning, inter-animal aggression and poor testis development [110,111]. These findings collectively justified the need to begin applying AI within the blackfooted ferret breeding program.…”

“…Previous research revealed that age (1-5 years) did not affect semen quality and testosterone concentrations [8]; however, each diet treatment had four 1-year-old males and seven 2-to 3-year-old males to ensure the age class of the ferret breeding population was represented. The beef diet was selected as a treatment to assess whether this diet could be offered to ferrets as an alternative diet to the horsemeat diet.…”

“…Recent studies reported that the percentage of normal spermatozoa (sperm) morphology in an ejaculate ranged from 50% reported in 2000 to 16% in 2006 and 2007 [6][7][8]. Additionally, the average breeding success rates for females have declined from original breeding success rate of 70% (from 1987 to 1998) to 46% reported in 2013 [3].…”
