In this study we investigate the effect of nest box temperature and humidity on the growth and survival of approx. 700 mink litters. Surprisingly this study did not find any general biological explanatory temperature and/or humidity effects within days on the number of live born kits dying and kits growth. Instead parameters concerning litter composition did have significant effects on kit growth and survival. Litters with high number of Totborn and kit AliveD1 affected kit growth and kit viability negatively (increased number of live born kits dying), which indicates that factors acting on the female/litter prior to or during the parturition are an important determent of early kit growth and viability. The results indicate that females with large litters have less success by taken care of the kits compared to females with small litters. In addition litters with high mean growth were also litters with high kit survival until day 7 and female kits grow significantly less than male kits.
