1. Hydro-grid strip feeding method This is a method of feeding a cylindrical strip of feed on a special fenced food table. Production method of grid plate: Take a board 2 cm thick, 25 cm wide, and long according to the length of the feeding bait, and then drill a row of grid posts at a distance of 10 cm from the long edge. Centimeter (usually not suitable for climbing into the cubs), the thickness of the grid column is about half the size of ordinary bamboo chopsticks, length 15 cm, nails can be on the grid hole. After the board was made, it was placed on the edge of the pool with a 30 degree angle to the horizontal plane. The bottom of the board was 2 centimeters above the water, and the bottom of the board was covered with a row of cement tiles for crawling. The thickness of the feed bar is based on the size of the gill. The general seedling stage (3-5 grams) is 1 to 3 centimeters in diameter, while the seedling stage (50 to 200 grams) is 3 to 5 centimeters in diameter, and the pupal stage (200 grams or more) is 5 to 8 centimeters in diameter. You can. When feeding, the strips are placed on the material board, and then some of the grid nails can be gradually removed to increase the grid pitch according to the growth of the roaches so that the roach can feed into the head and neck. The advantage of this method is that the feed is eaten in water. Because Taichung is blocked by a fence, feed can't get into the water, and crickets can't just climb onto the feed board to scratch the feed. Because the feed strips are relatively thick, the feed will not spoil even with a bit of moisture, and when the food is eaten, it will bite and eat as much as possible, and will not spill the feed into the water, thereby reducing waste and water pollution. After 3 hours of feeding, any remaining feed is easily retracted. The feed board can also be wiped clean with a rag, because the board can grasp the amount of food, but also easier to adjust the amount of feed. Through experiments, feeding by this method can reduce the bait coefficient between 05-1, and the number of water changes is also reduced by about 1/3 compared to the method of scattering particles on the feed table. It is currently a better water-feeding method. . This method is also suitable for outdoor intensive culture ponds. 2. Underwater cage feeding method in some temperature-controlled greenhouses with poor thermal insulation performance, large space environment change, and high humidity, since the water table feeding will affect the normal feeding due to the above environmental changes, underwater feeding can be adopted. law. However, in order to attain the goal of underwater feeding that is neither wasted nor eaten, the following conditions must be met: 1 The adhesiveness of the feed must be better than that of the water-fed feed, and the blisters should not be disintegrated within 4 hours; 2 it is better Water transfer facilities, underwater temperature control can be adjusted with high temperature water, such as when the pool water temperature below 29 °C can be used 33 °C warm water adjustment. This method is generally more water-consuming, and then it is heated directly with steam tubes under water. It is also useful to increase the temperature of the hot water circulating in the bottom of the pool; 3 to have good oxygenation facilities; 4 to use light energy to cultivate organisms in the water, so that the water has a better ecological environment; 5 must have Scientific and reasonable feeding methods; 6 such as lighting greenhouses in the pool is best to set a small sun back table. Here are some specific methods for strip feeding in underwater cages. The first is to make feed boards. The feed board can be 3 cm in thickness, 12 cm in width, and the length is set according to the length of the pool side at the feeding site. The method is the same as that in the water fence. However, the fence cage must be fenced on both sides so as to avoid crawling into the feed plate during eating. For bad feeds, put a row of cement tiles at the bottom of the feed plate. Place the tiles 15 centimeters away from the surface of the water. Place the feed plate flat on the cement tile after placing it. Place it on the brick after placing it. Press it to avoid turning or tilting the feed plate. Before feeding, the feed and water are mixed well with a mixer, and then the feed is used to make the same strip feed as the feed. When feeding, the feed can be placed on the feed plate flat. About 3 hours after feeding, the feed plate was taken out, the remaining bait was taken, and the material was wiped. This method is less polluting and the feed waste is less than direct scattering of particles on flat cement tiles. 3, outdoor intensive breeding pool feeding method Outdoor intensive intensive pool, can also use the above method, but it should also have the following conditions: First, catch rain shield on the material board; Second, when feeding underwater, The wild fish in the pool must be removed first.

In the Arbas region of 105° east longitude and 40° north latitude where the temperature fluctuation between day and night can reach 50 degrees in winter, there is an essential native goat breed, the purebred Arbas Baby Cashmere Goat, which features thin and soft hair, a pair of horns and pink ears. Arbas Baby Cashmere Goat looks small yet are the nobles of goats.
The famous Arbas Baby Cashmere Goat, as a rare breed living in the Ordos Plateau of Inner Mongolia, is concentrated in Otog Banner, Otog Front Banner and Hanggin Banner in the western part of the Plateau. Sumu, Arbas, Otog Banner is the primary production area of Arbas Baby Cashmere Goat for its favorable natural environment, with Arbas Mountain in the west, vast natural pasture in the center and desert steppe in the south. The semi-arid steppe climate provides excellent conditions for animal husbandry.
Due to its location in the desert steppe, the area is dry and windy with little rainfall and much sand. The temperature difference between day and night is extremely high, and the annual average temperature is 6.4 °C. In the long, cold and dry winter, the lowest temperature reaches -30°C to -40°C late at night, while in the short, hot and arid summer, the highest temperature is 36.4°C and the lowest -32°C, with annual precipitation between 200mm to 400mm. The adorable, lovely and lively Arbas Baby Cashmere Goat grows in such extremely harsh conditions, thus can produce rare and quality cashmere.
Arbas Baby Cashmere Goat`s two coats are pure white. The top layer or outer coat is bright and coarse guard hair to protect the undercoat that is softer and finer down. The quality of the cashmere fleece is determined by three indicators: the diameter, length, and density of cashmere fibers. Due to its unique genes, Arbas Baby Cashmere Goat has a superiority that can never be duplicated. Its secondary hair follicle is smaller than those of other goats, and its cashmere has an average diameter between 13μm to 15 μm. It can even produce cashmere with a perfect diameter of 14.5μm, with a pure cashmere content of over 55%, which is unique worldwide. The preciousness of cashmere results from the small amount of production of each goat. Therefore, Inner Mongolian Arbas Baby Cashmere Goat was officially named by the People`s Government of Autonomous Region in 1988 and was listed on the National Register for the Conservation of Animal Genetic Resources as Class-1 protected breed by the Ministry of Agriculture in 2001.
