鹿茸仅见于公鹿。母鹿不长茸。从组织学角度来看，鹿茸是一种未钙化的角质组织，它的生长是有规律的，具有周期性特点，在不同生长期限内收获的鹿茸，分别为初生茸、二杠茸和三杈茸等几种。
Antler found only in Bucks. Doe not long Velvet. From the histological point of view, is organized in a horny antler is not calcified, its growth is regular, periodic characteristics in different growth period of harvest velvet, were the primary Velvet, two and three - branched Antler Velvet several.
1.初角茸。初生的公鹿在它的额顶左右两侧的皮肤上，各有一个呈皱褶状、上面附有旋毛的角痕。梅花公鹿到了10个月龄左右，就长出一对茸角。因为是第一次生茸，故又称“初角茸”、初生茸，因其角上布满茸毛，所以又 叫“毛桃茸”。初生茸呈直杆状，无侧枝，一般当其长度为15—20厘米时便可收割。以后茸角的局部皮肤萎缩，嫩角慢慢变成硬角，硬角于第二年自行脱落。但新的嫩角又重新再生长出来。
1. First angle Velvet. Nascent stag on the skin frontoparietal its right and left sides, each with a crease-like form, with corner marks Trichinella above. Plum Bucks to 10 months or so, grow one pair of antlers. Because it is the first secondary Velvet, so called "early corner Velvet" Velvet newborn, because the corners covered with hair, so they called the "Velvet peaches." Velvet was the primary rod-straight, no collateral, generally when a length of 15-20 cm can be harvested. After antler local skin atrophy, apprentices gradually become hard angle, the angle in the second year of hard off on their own. But the new apprentices and re-grow back.
2.二杠茸。公鹿在2岁以后，在每年的4月其角盘（即硬角脱落后遗留下的底部骨质组织，呈圆盘状，又名花盘）脱落，慢慢生长出茸芽，大约10天之后，茸芽生长出一侧枝，这样的鹿茸，称“二杠茸”，也叫二杈茸。在此期间，茸芽也不断增大，其长度和宽度都大大增加。
2. Velvet two bars. Bucks after 2 years, in April of each year its angle drives (ie hard off the bottom corner aftermath of bone tissue, disc-shaped, also known as disk) off, dried buds grow slowly, about 10 days later , velvet buds grow out of a collateral, such as velvet, called "velvet two bars," also called the second branched velvet. In the meantime, Velvet Bud has continued to grow, its length and width are greatly increased.
3.三杈茸。鹿茸长到二杠茸时如果不将茸角割下，它又继续生长，大约经过20天，再长出第二个侧枝。这样的鹿茸，就称为“三杈茸”了。从幼嫩的茸芽，生长到三杈茸，一般要经过70—75天左右。
3. The three - branched velvet. Velvet antler length to two bars if you do not cut off the antlers, it continues to grow, after about 20 days, and then the second lateral branches grow. Such velvet, called "three - branched velvet" the. From the Velvet young shoots grow to three - branched velvet, generally after 70-75 days.
4.鹿角。可以这样说，茸芽是最幼嫩的；二杠茸的质地也很嫩稚；三杈茸以后，茸的角化程度逐渐增加。野生鹿因为没有割茸，可以长出更多的分杈，茸角完全老化。梅花鹿茸如果不每年及时割茸，也会老化成鹿角。
4. antlers. It can be said, it is the most tender shoots Velvet; two bars Velvet texture is tender and juveniles; after three - branched velvet, Velvet keratosis degree gradually increases. Wild deer because there is no cut and dried, you can grow more forking, antlers completely aging. Antler Velvet if not cut per year, will be aging into antlers.
5.采茸年限。公鹿自1岁有初生茸开始，每年更换茸角，一直到老。从经济利益考虑，人工饲养用于割取鹿茸的公鹿，利用期限一般到14岁左右为宜。因为在此之后，鹿茸的产量已明显下降。
5. Mining Velvet life. Bucks from 1 year old newborn Velvet have started to replace antlers each year, until the old. Benefit from economic considerations, in captivity for stag antler excised using the general term to around 14 years of age is appropriate. Because after this, antler production has dropped significantly.
