Submerges must control light

The so-called illumination is to simulate changes in natural light cycles, which is breeding, and the removal of the mulching is suitable for light time and strength to develop the water production faster in the direction of adapting to human needs.
In the evolution of the mink, its growth and development and variations of breeding have formed a secret connection. In the natural state, the mink is replaced with the season, that is, the change of the natural photop cycle is reproduced once a year, and the hair is twice. In the artificial controlling state, the mink can be propagated early, effectively shortening the breeding cycle, saving the cost of breeding.
is a personal opinion, for communication, misupply. At the same time, you can make the mink winter skin in advance, slaughter, save feed spending and management fees, and greatly reduce production costs. The artificial controlling plan is not related to the date that starts shortening the sunshine. Even in the hot summer, it can also promote the summer long winter hair.
However, in production, attention should be noted that the winter hair growth of the mink has an endless period. After the winter, the lighting time is extended, although accelerated organ development, but does not cause summer hair growth until Xia Mao began to grow.
If the light is extended before the mature of winter, winter hair development is stopped, and the growth of sexual organs will be inhibited. Therefore, the breeding site should pay attention to the best time of artificial control.
The production is generally controlled from December 21, starting 1 hour of light every day, extending to 8 hours a day, then adding 15-30 minutes every 5 days, On May 1, the number of sunshine was 15 hours and 25 minutes.
With this method, it is possible to significantly improve the breeding rate of the mink. To promote the maturity of winter, the production is generally controlled on June 21, most of which use 40 watt sunlight illumination,
The artificial light cycle changes to the local natural photop cycle variation speed 2 times, adjusted once a week Make the illumination time to shorten, so that winter hair is rapidly developing, usually mature in winter fur on October 6th.

After 7-8 days after the bundle, the light is extended with the light, and the number of lights per day reaches 14.5 hours, and the controlled cashed small chamber cover is opened during the light, so that the mink is fully accepted until the start of the child, and the glory will be stopped. This method is used. The initial bubble is strong, lively, and is higher than that.
