Illumination is one of the important environmental factors for special animals. It plays a decisive role in the growth and development, breeding and production performance of special animals.
The fox promotes the fox fur to mature in advance: the fox is a seasonal furry animal, it grows off the winter hair in the spring and grows the summer hair, and in autumn it removes the summer hair and grows the winter hair. With reference to this rule, during the long summer sunshine period, daily reduced daylight treatment is applied to promote the growth of winter fur. The fur can be matured one month earlier and the feed cost and labor cost can be reduced.
Sika deer increase antler production: Light has a great influence on the growth of pilose antler, so deer can use light control to promote the growth of pilose antler. The method is: January 1 to April 5 as the whole process, 1 to 10 days, 12 hours of light each day; from January 11 to February 15, gradually increase the light time to 16 hours 12 minutes a day. In the future, instead of gradually shortening the lighting time until 12 hours per day. Effect: Obviously increase the production of head stalk velvet, second stalk antler is charged 30 days in advance.
The coypu improves mating performance of male and female Japanese coypu. From March to October, it was the breeding season of the coypu. In this season, the male and female coypu was irradiated with incandescent light every night for 2 to 3 hours. Stimulate their anterior pituitary gland, activate and secrete gonadotropins, thereby promoting sperm production in male rats, speeding up oocyte maturation and ovulation, promoting mating, and increasing fertilization rates.
Hydra fertility: Increased female ferret breeding fetus rate: From December 21st onwards, increase the daily light by 1 hour; on January 1st, increase it by 15-30 minutes daily, until May 1st of next year, to reach daily light. 15 hours and 25 minutes.
Increase the survival rate of larvae: From the 8th day after the end of the breeding period, the females will be exposed to light for 14.5 hours per day until the litter stops lighting.
Promote the early maturation of leech winter fur: under natural light, after the autumn equinox, the otter will fall off and the winter fur will grow. After that, with the shortening of the sunshine time, after about 70 to 80 days, the winter hair will develop and mature. This is a short day of sunshine. reaction. Regulating lighting is to simulate the shortening of this natural light and accelerate the realization of this short-day response. The specific method: starting from June 21st, with 40 watts of light lighting, daily declining light time, prompting the rapid development of winter hair, about October 6 winter fur mature.
Turtle Increases Female Egg Spawning Capacity: Starting from early summer every year, hanging a sunlamp above a turtle pond and turning on the light 2 hours before dawn can induce many insects to fly for female turtles to catch feed and increase nutrition. In early autumn. Such light and nutrition can promote the maturation of female follicles, increase the amount of eggs laid, and increase fertility. This method is effective for different species of female turtles.
