The present study sought to find out how carotenoid supplement influences on body weights, feed consumption and reproductive success in standard farm mink Neovison vison. Carotenoids were from microalgae Haematococcus pluvialis. A dose of carotenoid supplement of 0.20, 0.25, 0.20, 0.20, and 0.10 g-animal was added daily in feed in February, March, April, May and June, respectively. Experimental groups were: 1 control group, and 2 carotenoid group. Each group comprised 100 females and 25 males. The results showed that appetite of animals in all groups was good. Significant differences were not found in body weights before breeding. However, weights of control females were significantly P < 0.05 lower compared with those of carotenoid fed animals when kits aged 21 days. At the age of 21 and 42 days, body weights of kits were similar in both groups. However, kits from carotenoid group tended to grow better P < 0.1 than those from control group. Number of whelped females was lower in control group 81 vs 85 females. Number of barren females was higher in control than in carotenoid group 16 vs 13 females. Significant differences were not found in number of kits per mated and whelped female. Number of lost kits was higher in the control group at the age of 21 days 24 vs 20 kits and the age of 42 days 40 vs 26 kits. The present study showed that carotenoid supplement could be used in mink diet. The results are promising, but require further studies before final implementation.
