The quality of the stag's husbandry and management plays an important role in improving the reproductive rate of the deer, the production performance of the offspring, and the quality of the entire deer herd. According to the physiological changes of the stag in different periods and the characteristics of the demand for nutrients, there are four feeding stages in the stag feeding, namely the velvet period, breeding period, recovery period and early velvet period. The stag antler period of deer feeding and management during the antler period means that the deer needs to go through 25 days from the time of deer horniness or long velvet to velvet antler. Sika deer is generally detached from the dish at the beginning of January. In February, it is a flourishing period. In March, it is the late period of velvet and the period of growth of regenerated velvet. The physiological characteristics of the male deer during the period of antler: loss of libido, atrophy of testis, increased appetite, vigorous metabolism, increased food intake, and rapid growth of antler. In the antler period, the stagnation of the deer in the morning and evening, the quality of the velvet antler, and the level of the output all depend on whether or not the deer group has implemented scientific feeding management. This period of feeding and management is good, deer fertility, take off early, antler growth fast, high yield, good quality. It has been observed that antler grows extremely fast during the antler period. For example, a 1-year-old sika deer grows for about 22 days on average, and an average daily weight gain of 5 grams; the 2-year-old stag velvet gains an average of 1 gram per day. Up to 52 grams. Therefore, the stag needs a lot of nutrients in the velvet period, especially the nutrition of protein, minerals and vitamins, especially the supply of nutrients containing sulfur amino acids such as cystine and methionine. The stag was raised during the period of antler feeding: The buck's diet should be full-priced and balanced, and the ratio of legumes and bean cakes could be increased in the diet to improve the quality and palatability of the diet. In the diet, 23% of the leguminous sub-materials are used, 11% of the grasshoppers are actually used, 6% of the bran is gluten, and the juicing material and the green coarse material can be freely eaten depending on the local feed conditions, or the daily supply of concentrate is 36 kg. , Green coarse material 12 kilograms; Juicy material 6 kilograms; 122 grams of bone meal or stone powder, salt 62 grams. In addition, 63% of fishmeal and 23% of sodium bicarbonate (sodium bicarbonate) and soybeans can be used to feed deer. The results are also good. During the velvet period, balanced, regular and quantitative feeding should be carried out. Concentrate should be fed 6 times a day. Drinking water should be clean and adequate. Areas with rich green feeds should try to meet their needs and allow them to eat freely when necessary. In this way, the deer absorbs the feed well and the antler grows particularly prosperous. In the late period of the antler's use of the antler, it is possible to begin feeding a large amount of green feed and reduce 6% of the concentrate in the ration after harvesting. Appropriately control the public opinion after finishing reclaiming. Immature stags may not be reduced. Practice has proved that timely reduction of materials before mating, stop the fine material can make the non-mating of the stag when the mating period arrives, lyrical decline, reduce sexual desire, reduce the battle between the Bucks top collision, climb phenomenon, reduce casualties, and promote their digestive function Normally, there is basically no hunger strike during the breeding period of individual stags, which is also conducive to a good appetite of the stag in the late breeding period, and to increase growth and rejuvenation. The grazing stags grazing twice a day, feeding the proper concentrates and mixes after her husbandry and ensuring that there is enough drinking water every day. In addition, a salt tank should be set up in the circle, and a certain amount of salt or salt minerals should be put into the salt tank for about 5 days to feed the deer. Practice has shown that adding antler and antler does not have the same effect. The velvet antler stems that grow without lifting the antler material are dry, small and dull, light in weight, and the grade is decreased; the antler that grows from the antler material is added, the branches are thick, the thickness is the same from top to bottom, and the oil shines and the head is plump. General velvet weight can be increased by 23%, and the level can be increased by one level. In order to increase the output of pilose antler, the following management measures should be taken: Increased light and deer antler. Several simple plastic greenhouses are built according to local conditions. The area is about 35 meters. It starts from the spring each year (preferably from the beginning of March). It can increase the light time by 2 hours per day, and the days of increased light can be 22-23 days. The deer in the shed is kept in the same conditions as the open air. Increase the light to support the deer, the deer can be dehorned one day in advance. The stag in natural light has not been horned off in the month, but the deer in the shed increased its shine in advance on June 62. The stag head velvet production can be increased by 23%, especially the rejuvenating antler, which not only grows two bars of velvet but also doubles the average yield. 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 deer's appetite increases and metabolism is vigorous. According to the experiment, two grams of compound humic acid sodium were fed to the male in three separate batches every day. The solid compound humic acid sodium was diluted by two times in water 6 hours before feeding and then fed with the concentrate and fed continuously for 52 days. Until the velvet was harvested, the antler produced 252 grams, while the control group produced 2 grams of the antler, which increased the weight by 53%. The management of the stag antler period: The stag antler's stag due to age, digestive physiology, nutritional needs and metabolic levels are different. Therefore, the stag should be managed by age and physical grouping, so that it is easy to grasp the nutrition level and feeding amount of the diet. The Bucks in this period are docile in character, but they must also strengthen their management to prevent the worries of outsiders and other animals from panicking the deer and causing damage to the deer and damaging the deer. The stag-and-male stag must be singled out in a timely manner, isolated or temporarily placed in the unbred deer group. During the velvet period, we must carefully observe and record the fall of the horns of the stag, the growth of velvet antler, grasp the growth speed of the antler, and timely make velvet work, so as not to miss the opportunity and affect the quality of the antler. For the individual new antler has grown, but the corner plate is still not off, should Baoding deer in time to pull out the lasting corner plate, so as not to hinder the growth of new antler and prevent the emergence of strange corners. The deer's house, sports ground, barracks, and separation wall shall be inspected and repaired, and all sharp obstacles shall be removed to avoid damaging the antler. It is necessary to thoroughly clean the playgrounds, deer's quarters, wash feeders, drinking troughs and other feeding equipment every day. In particular, remove the remaining feed every day to prevent moldy feeds from being eaten by the deer. Maintain a clean breeding environment and pay attention to the cleanliness of feeding equipment, feed, and drinking water. In the hot summer season, it is necessary to pay attention to the cooling of the summer heat, conditional deer farms, can set up a number of shade sheds in the stadium, but also the addition of cold pool or shower facilities.
