The deer field is constructed in a place with high dryness, leeward sunshine, good drainage, and a convenient water source to build a deer farm. Deer activity is larger, the deer house covers an area of ​​2-3 square meters, and the activity area is 8-10 square meters. Use slate or smooth wooden boards or cement boards to cover the floor so that the excrement can be easily cleaned. Set railings around the deer field, 2.5 to 3 meters high, to prevent deer jump and escape.
Second, how to improve antler production
1. Controlled deer and deer grow fast: The deer households can draw several simple plastic greenhouses on site, covering an area of ​​about 125-225 square meters, and putting on 100-150 watt mercury lamps on the roof, 4 lamp heights The ground is about 2.5-2.7 meters and the illumination is about 500 degrees Celsius. Every year from the beginning of spring (preferably from the beginning of January), the daily illumination time can be increased by 6.8-9.5 hours, and the number of days of increased sunshine can be 50-60 days. The deer in the shed is kept in the same conditions as the open air. It has been experimentally confirmed that the deer can control the deer and the deer can exfoliate the antler 38 to 39 days earlier. The male deer in natural light has not been dehorned in April, but the deer under the light control of the greenhouse can be decapitated early on February 20 to invent the conditions for prolonging the growth and development of the velvet. As a result, the male deer head velvet production can be increased 0.88% - 13.8%, especially the rejuvenation antler, not only grow two antler, and the yield can be increased by 2-3 times (290% -310%).
2, sodium humate additives: Humic acid sodium is a very complex structure of multi-organic acids, it can enhance the body's oxidizing acid vitality, growth metabolism and the ability to absorb nutrients. Therefore, using sodium humate as a deer feed additive, the appetite of the deer grows, the metabolism is lush, and sufficient nutrition is provided for the growth of the antler. According to the experiment, each male was fed with 0.2 g of sodium humate three times a day, and the solid compound sodium decanoate was diluted with water to 0.05% for two hours before feeding, and the pH was 6.5. Thereafter, the concentrate was fed. Continuation of feeding 70 days until the harvest antler. Results The experiment group produced 575 grams of pilose antler, while the control group produced 490 grams of antler, which was increased by 17%.
Third, how to process and cut pilose antler
1. Take the velvet at the right time: The little male deer takes the first year of velvet in mid-June. For a deer that is more than two years old, the antler must be grown into two bars, the top is concave, and the third branch is harvested when it has not yet grown. The velvet antler at this time is of good quality and high value. Usually, the velvet antler is taken in late June and the second pod is taken in late August. Before taking the antler, drunk drugs should be injected on the hips. Usually, a deer with a weight of 100 kilograms is injected with 0.3 ml of succinic choline chloride injection; after the injection, 2 ml of nikethamide is injected with 6 ml. After the deer has been injected with the anesthetic, it is sterilized with iodine around its root, and then the velvet vinegar is disinfected with iodine and used with hemostatic drugs or pounded barbedgrass (a kind of hemostatic grass) and lime. Mix appropriate amount of keel powder and apply it to the antler to stop bleeding.
2, velvet processing: 1 row of blood. Insert the injection needle into the antler and inject air with the pump needle so that the blood flows from the antler to the entire mouth of the antrum. Conditional can also be performed with a blood ejector. 2 disinfection. Disinfect the pilose antler with potassium permanganate solution and alkaline water, wash off the dust and impurities on the velvet, and then use a thick thread at the mouth of the velvet antler to sew a few needles on the skin fork to prevent the skin from slipping off and affecting the quality. 3 boiled. The goal is to make the remaining blood in the antler flow out, so be careful not to let the boiling water immerse in the gargle, to prevent blood clotting and affect the quality of antler. The method is: Hold the mouth of the antler and put it into the boiling water for 3 seconds, take it out and let it dry for another 3 seconds. Repeat this for 10 minutes, then extend the cooking time again to 5 seconds. After 15 minutes, each cooking time was extended to 20 seconds and repeated for 30 minutes. When the velvet antler sheds foam, it shows that the remaining blood in the antler has been cleared. After that, the whole body was shaken and submerged in boiling water. After 5 seconds, it was taken out of the water for half an hour before cleaning. 4 baking. Hang the dried antler in the drying room. The first day baking temperature is 35 °C -40 °C, the next day is 40 °C -45 °C, the third day is 45 °C -55 °C, the highest but 60 °C until drying. Finally wash and sterilize (do not wash the mouth), after drying to sell.
