First, choose the species of deer Chinese domestic deer are mainly deer, red deer, white-lipped deer, sambar and so on. Most of the artificial rearing was spotted deer, followed by red deer. The economic value of deer and red deer is basically the same. In deer velvet quality, red deer is inferior to deer. Deer need to choose good breed deer first, because high-yield deer and low-yield deer, not only the velvet output is different, but also the quality and price of antler are quite different, the economic benefits of the two are very different.
Second, science feed deer can use green feed, dry rough feed and concentrate feed, mineral feed. The green and roughage mainly include crop straw, alfalfa, leaves, hay, root and stem feed, and silage, and free-feeding feeding methods are used for green roughage. In addition to feeding roughage, 1.0-1.5 kg of concentrate is added daily. The concentrate feed is mainly made up of energy feeds such as corn, wheat, sorghum and other cereals, protein feeds such as animal protein and various kinds of cakes, and bran type feeds. General energy feeds account for 50-60%, protein feeds 15-20%, and bran feeds 15-25%. The amount of bone meal and salt added per day is based on the weight per hectare, bone powder is 15-20 grams, and salt is 20 grams. It is necessary to adopt the principle of feeding after roughening. In the absence of green season in winter and early spring, 1.0-1.5 kg of succulent feed such as carrots, silage, and leaves are supplemented. Male deer should increase the amount of concentrates, minerals and succulent feed during the breeding period and the long-antler period, as well as during the pregnancy and lactation of the doe. The doe needs to feed more raw material before and during the pregnancy, and later feed the fine material with small size and excellent quality. Feeding times are generally 3 times a day, and if necessary, they are fed once a night. According to data, during the period of male deer antler, alternating addition of cobalamin and animal growth hormone in feed can increase velvet output.
Third, the timely mating generally to 1.5 years old, the deer has been sexually mature, but this time the body is not yet mature, the appropriate mating age should be 2.5 years old. The breeding season of deer is from late August to November. Doe estrus every 18-24 days for 2-4 days. The male deer should choose a strong male deer that grows fast, has many velvet, has strong disease resistance, and is genetically stable. Generally, one male deer is placed every 15-20 deers. After the deer estrus, the breeding should be placed in due course, usually 2-3 times. During the deer’s gestation period, the deer had 231-236 days and the red deer had 240-250 days. One to two litters per birth.
Fourth, science and cutting velvet and velvet first cut antler and grow to 3 centimeters, cut from the top of the knife longitudinally 1.6-1.9 cm, can greatly increase the output of pilose antler. Harvesting time should be appropriate, early or late harvest will affect the yield of velvet. Three-pronged antler is suitable for harvesting in 65-70 days and four-pronged antler in 75-80 days. There are two kinds of sawing and ringing methods and anesthesia. The anesthetic is usually intramuscularly injected with cocoa and Jingsongling. The deer is anesthetized and fell down 15-20 minutes after injection. Sawing sawing should be light, fast, and flat. After sawing, the medicine should be even and the deer should be fast. In addition to the above four points, we must also carefully manage it.
Demetdent announced the release of the our company`s wet/dry milling machine. It was added to the Demetdent family of Dental Milling devices in answer to our lab and dental users need for a wet-milling option to handle many of the new brands and materials. The wet/dry milling machine fills a gap in many dental restoration workflows, giving laboratories the added flexibility of milling glass ceramic, composite resin materials that are becoming increasingly popular in the industry due to their high translucency, increased flexural strength and hardness, and overall aesthetic value for inlay/onlays.
