1周岁梅花公鹿平均每月增重率为4．2％，也就是说此时还处于生长发育阶段，各组织器官还没有完全成熟，刚开始生长初角茸，此期所需要的营养物质，不仅需满足其生长发育的需要，还要满足其生茸的需要，因此，这个时期对日粮中的营养水平要求较高。此期饲粮中能量（总能）和蛋白质（粗蛋白质）适宜水平分别为17．35兆焦／千克和22．4％；每千克代谢体重每日对代谢能。可代谢蛋白质。钙和磷的需要量分别为991千焦、8.05克、0．78克和 0．45克。平均每只鹿每天对能量（总能）和粗蛋白质的需要量分别为37兆焦和478克。
1 year old plum Bucks monthly average weight gain was 4.2%, meaning that at this time in the growth stage, tissues and organs are not fully mature, the beginning of the growth of early Velvet corner nutrients needed for this period not only need to meet the needs of its growth and development, but also to meet the needs of their students Velvet, therefore, this period of dietary nutrient levels higher. This period of dietary energy (total energy) and protein (crude protein) suitable levels were 17.35 MJ / kg and 22.4%; per kilogram of body weight daily metabolic energy metabolism. Metabolizable protein. Calcium requirement was 991 kJ, 8.05 grams, 0.78 grams and 0.45 grams. Average per day deer energy (total energy) and crude protein requirements were 37 megajoules and 478 grams.
2周岁梅花公鹿平均每月增重率为1．9％，其个体生长发育已接近成熟。此期公鹿开始生头茬茸，生茸能力（即产茸量）较低，但采食量开始增加，对粗饲料的采食能力增大。因此，这时对日粮的营养水平要求相对较低，此期饲料中总能和粗蛋白质的适宜水平分别为16．18兆焦／千克和18．5％。每千克代谢体重每日对代谢能、可消化粗蛋白质、钙和磷的需要量分别为819千焦、6．01克、0．75克和0．41克。
2 years old plum Bucks monthly average weight gain was 1.9%, the growth and development of individuals nearing maturity. This first crop of students began Bucks Velvet antler capability (ie yield Velvet) lower, but began to increase intake of roughage intake capacity increases. Therefore, at this level of nutrition dietary requirements are relatively low, the total energy of the feed and the optimal level of crude protein were 16.18 MJ / kg and 18.5%. Per kilogram of body weight daily metabolic energy metabolism, digestible crude protein, calcium and phosphorus requirements were 819 kJ, 6.01 grams, 0.75 grams and 0.41 grams.
3周岁梅花鹿公鹿每月平均增重率为0．4％，基本达到体成熟。其产茸量开始增加，此期饲粮中总能和粗蛋白质的适宜水平分别为16．55兆焦/千克和19．0％；其精料补充料中的适宜钙、磷水平分别为1．23％和 0．64％；每千克代谢体重每日对代谢能、可代谢粗蛋白质、钙和磷的需要量分别为890千焦、5.63克、0．85克和0．44克。
3 years old male sika deer monthly average weight gain of 0.4%, basically reached maturation. Velvet began to increase its production capacity, the total energy of the diet and appropriate levels of crude protein were 16.55 MJ / kg and 19.0%; suitable for its calcium concentrate supplement feed, the phosphorus levels were 1 .23% and 0.64%; per kilogram of body weight daily metabolic energy metabolism, metabolizable crude protein, calcium and phosphorus requirements were 890 kJ, 5.63 grams, 0.85 grams and 0.44 grams.
4周岁梅花鹿公鹿生茸期饲粮中总能和粗蛋白质的适宜水平分别为19．39兆焦／千克和15．9％；每千克代谢体重每日对代谢能、可代谢粗蛋白质、钙和磷的需要量分别为941千焦、5．41克、0.85克和0．43克。
4 years old male sika deer antler of total energy diet and appropriate levels of crude protein were 19.39 MJ / kg and 15.9%; per kilogram of body weight daily metabolic energy metabolism, metabolizable crude protein, calcium and phosphorus requirement was 941 kJ, 5.41 grams, 0.85 grams and 0.43 grams.
5周岁梅花鹿公鹿生茸期饲粮中总能和粗蛋白质的适宜水平分别为16．72兆焦／千克和16.6％；每千克代谢体重每日对代谢能，可代谢粗蛋白质、钙和磷的需要量分别为782千焦、5.38克、0．79克和0．43克。
5 years old male sika deer antler of total energy diet and appropriate levels of crude protein were 16.72 MJ / kg and 16.6%; per kilogram of body weight daily metabolic energy metabolism, metabolizable crude protein, calcium and phosphorus the requirements were 782 kJ, 5.38 grams, 0.79 grams and 0.43 grams.
