Second, how to improve antler production
(1) Controlling light deer, deer and fast: Deer households can construct several simple plastic greenhouses according to local conditions, occupy an area of ​​about 125-225 square meters, and install four 100-150 watt mercury lamps on the roof, and the lights are at high altitude. About 2.5 to 2.7 meters, the illumination is about 500°C. Starting from the spring each year (preferably from the beginning of January), the daily illumination time can be increased by 6.8 to 9.5 hours, and the increase in the number of days of illumination can be 50 to 60 days. The deer in the shed is kept in the same conditions as the open air. It has been proved by experiments that the deer can be controlled by the light and the deer can be decapitated for 38 to 39 days in advance. The male deer in natural light has not been dehorned in April, and the deer under the light control of the greenhouse can be decapitated on February 20 in advance to create conditions for prolonging the growth and development of the velvet. As a result, the male deer head velvet production increased by 0.88% to 13.8%, especially for the regenerative velvet, which not only grew two bars of velvet but also increased the yield by an average of 2 to 3 times (290% to 310%).
(2) Sodium Humate Additive: Sodium humate is a complex organic acid with a very complex structure. It can promote the body's oxidizing acidity, increase metabolism and absorb nutrients. Therefore, using sodium humate as a deer feed additive, the appetite of the deer increases, and the metabolism is vigorous, providing sufficient nutrition 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. Two hours before feeding, the solid compound sodium sulfate was diluted with water to 0.05%, pH was 6.5, and then the concentrate was fed. Feed it continuously for 70 days until it is harvested. Results The experiment group produced 575 grams of velvet antler, and 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 about the middle of 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. Generally, the velvet antler is taken in late June and the second pod is taken in late August. Before taking the antler, one should inject injections of drunken medicine on its hips. Generally, a deer with a weight of 100 kilograms is injected with 0.3 ml of succinylcholine chloride injection; after injection, 2 ml of nikethamide is injected with 6 ml. After the deer has been injected with the anesthetics and fell to the ground, it is sterilized with iodine around the root of the velvet. After the velvet is cut, the velvet vinegar is disinfected with iodine, and the hemostatic agent or pounded barbed grass (a kind of hemostatic grass) and Chen are used. Mix the lime with the appropriate amount of keel powder and apply it to the antler to stop bleeding.
(2) pilose antler processing: 1 row of blood. Insert the injection needle into the antler and inject air with the pump needle so that all the blood in the antler flows out of the fistula. Conditional can also be performed with a blood ejector. 2 disinfection. Disinfect the pilose antler in potassium permanganate solution and alkaline water, wash off the dust and impurities on the antler, 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 sliding off and affecting the quality. 3 boiled. The purpose is to make the remaining blood in the antler flow out, so be careful not to let the boiling water immersed in the gargle, to prevent blood clotting and affect the quality of pilose 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. Then, shake all the antler into boiling water, remove them after 5 seconds, and take them out for a half hour before cleaning. 4 baking. Hang the dried antler in the drying room. The first day baking temperature is 35 ~ 40 °C, the next day is 40 ~ 45 °C, the third day is 45 ~ 55 °C, the highest but 60 °C, until drying. Finally wash and sterilize (do not wash the mouth), after drying to sell.
Deer experience
First, how to build a deer field deer field construction choice Gaozhuang, leeward sunny, well-drained, convenient water source to build a deer field. Deer activity is relatively large, the deer house covers an area of ​​2 to 3 square meters per square meter, and sports ground is 8 to 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.
