The study was aimed to evaluate a possible effect of body condition of female farmed mink (Neovison vison) at the moment of conception on their prospective reproduction and behavior. 601 Perl mink females at age 1 and 2 years were assigned to one of five groups according to their body condition. The following parameters were analyzed: gestation and diapause lengths, litter size, live-born litter size, number of weaned per litter, female barrenness, and the incidence of fur-chewing. The effect

In both age groups, the shortest pregnancies and diapause periods were observed in the thinnest females. Fur-chewing was most often noticed in either the thinnest or the most obese animals; females of these groups also exhibited the highest rates of barrenness. Consequently, the lowest incidence of fur-chewing, female barrenness were found in females with ideal body condition.
