Velvet deer breeding technique

Deer with medicinal value are called velvet deer. Domestically domesticated velvet deer mainly include spotted deer, red deer, white-lipped deer and black deer. Antler Velvet is a valuable Chinese herbal medicine, which has the functions of stimulating the marrow, benefiting blood, aphrodisiac, strengthening gluten and strengthening bones. Others such as deer fetus, deer blood, deer muscle, deer whip, deer bone, venison, deer heart, deer liver and deer skin, etc., are superior pharmaceutical and industrial raw materials. The economic value of velvet deer is high, and wild resources are scarce. Therefore, raising deer is a good industry for farmers to shake off poverty and become rich. First, the deer's living habits Deer domestication has a short history, but still retains the wild habits, hearing, vision and smell developed, timid and frightened, quickly moved to escape. General male deer is more aggressive than doe. In natural conditions, there are many groups of activities, ranging from a dozen heads to many dozens of heads. They can use their strong social characteristics for domestication and grazing. Deer is a herbivore and has ruminating physiological functions. It feeds on various plants throughout the year. Grasses, crop stalks, and shrubs and shrubs are good feed for the deer. Under artificial rearing conditions, soybean cakes, corn, and bran can be used as supplements. Second, deer house construction deer field should be selected in the terrain Gaozao, flat wide, well-drained, sunny, rich grass, winter shelter. Deer nature, the sheds should be sturdy, the area of ​​each deer is 2 to 3 square meters, the stadium is 8 to 10 square meters, and the wall height is 2 to 2.2 meters. In the circle, paving bricks or cement floors, equipped with a wide sports field, there should be food troughs and sinks. Cover shacks to shelter from rain. Third, the main purpose of feeding and managing velvet deer is to obtain deer antler, so it is very important to maintain deer (deer's antler, doe does not produce antler). Feeding male deer can be divided into two stages: the early period (2 to April) and the velvet period (May to August); the breeding period (from September to November) and the breeding period (from December to January). After February, the weather is warmer and the sunshine is longer. To meet the physiological needs of male deer, we should gradually increase the concentrate. Can be fed a mixture of 1 to 1.2 kilograms per day, then 70 to 80 grams every 5 days, to the beginning of May increased to 2.3 to 2.4 kilograms. The protein-rich legume feed should account for more than 60%, salt, shell powder and other minerals feed 10 to 20 grams per day, if conditions can also feed some additives such as animal growth hormone. In July, the non-seed male deer used to saw the head stalks should reduce the amount of concentrate by 50% to 80% so as to avoid intense competition during the breeding period. During the breeding period, the male deer became agitated and agitated because of sexual urges. Loss of appetite required attention to care and reduced casualties. Feed should be diversified as much as possible, and give green feed and tuber feed. Mix feed for 0.5 to 0.75 kg per day. After the breeding period, the deer's nutrient decline, coupled with the cold weather, is a season for the deer to die easily. The roughage should be sufficient. Mixing concentrates should be 0.75 to 1 kg per day. The reproductive deer of the velvet deer is 2.5 years old and male deer 2.5 to 3 years old, but it is appropriate to use 4 to 5 years old breeding. Doe estrus cycle is 17 to 21 days, estrus duration 18 to 36 hours, gestation period 224 to 231 days. The estrus season of the female deer was from September to November, and the performance of the early stage of estrus and the mid-term performance was uneasy and waving. The genital area was swollen, congested and flowed out of clear mucus. After 12 hours of estrus, it was easy to breed. It is necessary to select male deer with high antler yield, robust traits, and good genetic performance as a deer. The breeding method currently uses 1 male and female mating methods, ie 1 male deer with 20-30 female deer, and the conception rate is above 90%. May-June is the doe's calving period. There is no more than one birth per litter, and the deer suckling period is two months. The male deer at the age of 1 produces the antler at the beginning of the year and the 2 year old antler. The age of 4 to 8 years is an engorged period. The production life can reach 12 to 14 years.

NVR, the full name of Network Video Recorder, is the storage and forwarding part of the network video monitoring system. NVR works with video encoder or Network Camera to complete video recording, storage and forwarding functions
After entering the 21st century, with the development of network technology, there is an increasing demand for video data storage through the network. The monitoring system with DVR as the core has further developed into a NVR system with network functions.

NVR, namely network video recorder, is the storage and forwarding part of the network video monitoring system. Its core function is the storage and forwarding of video streams. Compared with DVR, NVR has a single function. It does not have analog digital conversion and encoding functions and cannot work independently. It usually works with video encoder DVS or network camera IPC to complete video recording, storage and forwarding functions.

NVR has different product forms. Although its core function is the capture, storage, management and forwarding of network video streams, different companies have different designs to complete these functions and have their own characteristics
