Breeding minks should divide their nests in time

Timely nesting of young minks is not only beneficial to the growth of young minks, but also ensures the health of female minks.

(1) preparation before nesting before nesting, the cages used in the locality should be inspected first, the damaged cages should be repaired, and then all the minks should be disinfected and set aside. Then wash the required food plates and water boxes and disinfect them, and use them after dividing their nests.

(2) the first litter division should be carried out twice, the first time the age will reach 40 to 50 days old, the weight will be more than 250 grams (note that the weight is less than 250 grams, do not rush to separate the mink for a while, let the female mink keep for another period of time. In this way, the weak minks can quickly catch up with the sturdy young minks, and the young minks, which are not frightened by the distribution of all the young minks, are kept in a cage every 2 to 8. This has two advantages: one is to raise the temperature of the chamber through the mutual body temperature between the young minks to prevent them from getting cold. The second is to let the young minks who are used to group life gradually improve their ability to live independently and lay the foundation for the second litter.

For young minks who are used to group life, they will not adapt to the new environment because the living environment has changed, so they will scream from time to time. As a result, some young minks will have loss of appetite, diarrhea, prolapse of anus, urine dampness, gastroenteritis and other bad phenomena. At this time, the breeders should strengthen their sense of responsibility, if the box mat grass is contaminated, the food plate and water tank should be removed in time, and the hidden danger should be dealt with in time to ensure the normal growth of the mink. At this time, the feed should be a little thin, mainly fresh milk, sheep's milk, fresh eggs, high-quality imported fishmeal. Feed the young mink to ensure the palatability of the feed, which should be added at any time according to the growth needs of the young mink, so that the young mink can have enough to eat. After 8 days of feeding, the weight of the young mink soon reached 350 million 400 grams, at this time the young mink fully have the ability to live independently, and then divide the nest for the second time.

(3) in the second nest, all young minks are divided into two groups according to males and females, thus forming a large group of males and a large group of females, and then separate the large and small ones in each group of male and female mink, and put them in the same mink shed of male and female mink groups. The purpose of this is to make it easier for breeders to feed reasonably according to the size of male and female minks.
