Weasel artificial breeding

The weasel, a scientific name known as jaundice, is densely covered with hair, brownish-brown or orange-yellow, and has a high economic value.
First, feeding methods
1. It is advisable to open a captive breeding ground to 20m2. The perimeter of the field should be 2m above the wall and the inner wall should be leveled with cement. In the middle of the farm, stones, waste bricks, mud, etc. were piled up into small hills, and some caves were built with a depth of 50 cm and a height of 25 cm. Some grass was placed in the caves.
2, the housing (house) rearing room to be tight and solid, indoor erection of partitions, partitions placed on the nest box. The nest box is 20-30 cm high, 40 cm long and 40 cm wide, and the entry hole for diameter 7-8 cm is opened on the nest box.
3. The cage cage is composed of a wire cage and a nest box. The wire cage is 80 cm long, 70 cm wide and 40 cm high. The above door is set for feeding and cleaning, leaving a small hole at the bottom of the side to cross the nest box. The nest box is for the weasel to rest and give birth. It is slightly smaller than the wire cage and is nailed by a hard thick board.
Second, feeding and management
1, the feed formula is best fed to the weasel mixed feed. Mixed feed is mainly meat, and cereal feeds and vegetables are added. Non-breeding period, diet formulation: animal internal organs accounted for 40% (including fish and shrimp accounted for 1/4), silkworm cocoons accounted for 15%, bean cakes accounted for 10%, wheat bran accounted for 15%, clams accounted for 5%, radish accounted for 10%, Cabbage takes 5%. In addition, 2 grams of salt, 5 grams of bone meal, 5 grams of yeast, and 1 gram of cod liver oil are added per 500 grams of mixed feed. During pregnancy and lactation, it is necessary to increase the ratio of concentrate feed and daily feed, and feed animal feedstuffs such as loach, fish, etc., and the amount of animal feed can be increased to about 75%.
2. Feeding methods will be fed once a day in the morning and evening, 40% in the morning at 7-8 am, and 60% in the afternoon at 5-6 pm. When you feed, cut the food into small pieces. To stimulate appetite, stop eating once a week. The feed for pups is preferably semi-liquid viscous foods that are easy to digest and nutrient-rich, such as milk, eggs, chopped squid, etc.
Third, the reproductive period Weasels sexual maturity is generally about 10 months of age, males than females early estrus. From the beginning of March to the end of April each year is the estrus mating period. Male and female weasels usually take about 1 hour to mate. In order to improve the conception rate, the ratio of males to females during estrus should be 1:1-3, and multiple matings are required. The female weasel has a pregnancies period of 30-40 days, and the motherhood is very strong. In the 4-5 days before the birth, we will use our bedding to make circular nests in the cave. The birthing process takes about 20-30 minutes. The pups eat at about the age of 20 days and they are weaned at about 40 days of age. At this time, the litter can be divided and selected according to their physical strength.

As round type surgical lamp, flower type also has big lamp head and small lamp head; the big lamp head surgical lamp, we call it Creled3400, the small lamp head surgical lamp, we call it Creled3300, the design of the burner focuses on reducing turbulence and the fully enclosed streamlined lamp shade is well designed according to aerodynamic principles. The smooth and sealess surface design is especially suited to the clean needs of the medical environment.
