Testicular aspiration biopsy in evaluation of fertility of mink (Mustela vison)

Historical winter diets of mink (Mustela vison) in Nebraska

The annual reproductive cycle of mink (Mustela vison).

Reproductive organ development, plasma sex steroid concentrations and fur growth patterns were determined for pubescent and adult mink of both sexes, at 1tc~ 8-week intervals, between July and the following June. Plasma estradiol concentrations and weights (mg/kg) of ovaries, oviducts and uteri decreased slightly in both pubescent and adult females during the first half of anestrus (July to Oct...

Evaluation of the Bionic trap to quickly kill mink (Mustela vison) in simulated natural environments.

The Bionic trap, with a bait placed at the back of a 6 cm aperture plastic cone, successfully killed nine of nine wild mink (Mustela vison) in simulated natural conditions. The average times to loss of consciousness and heartbeat were estimated at less than 60 (+/- 26) sec and 340 (+/- 55) sec, respectively, after firing the trap. This study confirmed that the Bionic trap can be expected to ren...

Feed consumption and food passage time in mink (Mustela vison) and European ferrets (Mustela putorius furo).

The amount of feed consumed per day and the rate of food passage was measured in mink and European ferrets. Daily feed consumption averaged 40 and 42 g dry matter per kg body weight for male mink and ferrets and 53 and 49 g dry matter per kg body weight for female mink and ferrets, respectively. Using ferric oxide as a feed marker, no differences were observed in food passage time between mink ...

Prevalence of Antibody to Aleutian Mink Disease Virus in European Mink (mustela Lutreola) and American Mink (neovison Vison) in Spain.

The European mink (Mustela lutreola) has undergone a dramatic decline and is one of the most endangered mammals in the world. The invasive American mink (Neovison vison) is considered the main factor for this decline. However, the American mink's introduction and the subsequent ecological concurrence of the two species cannot solely explain the decline or disappearance of the European mink. Ale...
