The main production task of male deer species male deer is to bear the mating of female deer and obtain excellent offspring with high yield through the deer or artificial insemination. The second is the production of pilose antler. Because of the high heritability of pilose antler, the male deer decides the future productivity of the deer farm. Its physiological period is: the period of velvet from March to June, the breeding period from September to October, and the rest is the relaxation period. The larvae were gradually fed and fed for the previous month to reach 90% of the puddling period. During the velvet period, four times each day and night were fed under the condition of ensuring free access to green leaves. The amount of red deer given to the concentrate was increased from 2.0 kilograms in March to 4.0 kilograms in the period of intensive growth. The concentrate contains bean cake 30%, boiled soybean 10%, imported fishmeal 5%, cornmeal 45%, wheat bran 10%, calcium hydrogen phosphate 40g, salt 35g, additive amount, plus carrots accounting for 50% concentrate (or silage carrots) are fed together with the concentrate. After sawing and velvet, we must adhere to the fine material, feed 2 to 2.5 kilograms of mixture every day and night, so that the sensation still maintains 90%, and begin breeding on September 15. If this is the case, you can use the trial breeding method. The soon-tested estrus will be allocated to the male deer lap to mate. The deer that has completed the mating should be dialed out in time. It can also be put in the end according to 1:15 ratio of male and female deer. The best method is artificial insemination. The breeding male deer can be used after the artificial insemination of the doe. After the breeding is completed in early November, feed green feed (such as carrots) should be stopped one month before the velvet to prevent the estrus from becoming unstable. The male deer produced by the male deer is adult male deer. The purpose of feeding is to produce pilose antler, whose diet formula is basically the same species of deer. The velvet period is the most vigorous period for male deer metabolism. Feed intake is two-fifths larger than usual. At this time, full-price rich nutrition is needed and must be met. The male antler's velvet period is divided into three stages: the sealing period (about 10 days), the period of fork (11th to 45th days, ie 35 days), and the growing period (from the time after the release to sawing 45 days or so). One month before the removal of the disk, increase the feed to 8.5 to 90%. During the break-off period, pay attention to the quietness of the circle to prevent the fight between the deer and the deer. No deportment of the deer and deer can be made at any time. The side disk that was removed late should be manually dismantled as soon as possible. After approximately 10 days from the release of the wax bowl, the wax bowl has been sealed. After the antler grows 3 to 5 centimeters in length, it begins to diverge. The double eyebrows grow three heads at a time (main trunk, first and second eyebrows), and stays long. After 35 days, the third eyebrow is grown and the period of the antler is divided. After the third eyebrows grew up, they began to enter the velvet. During the period of vigorous growth, the velvet of each branch is growing at this stage and grows quickly. At present, the main problem with the deer in the north of our country is the severe lack of green fodder (ie, vitamin feed) in the period of disc removal and bifurcation (from March to April). This shows that it is important to fight some willows, poplar twigs and deer in the early spring. Sex. After the production of male deer's head and velvet saw, first, the velvein can be injected to produce the regenerative velvet. At this time, it is also necessary to give enough condiment (1.5 kg can be used), which is still a period of velvet. After the period of velvet period, blood collection can continue to feed fine material (1 kg). If no blood is collected, concentrate is immediately stopped. Only rough feed is fed to control the sensation, and the sensation does not exceed 80% by the beginning of September. Enter estrus to take estrus control. In addition to stopping the concentrate, we must also limit the feeding of green feed. It is best to feed the corn stalks and hay stored in the previous year so that the gravidity will be controlled at 70%. By the end of October, the day will soon be cold, and each day will begin to increase by 0.5. Kilograms of fine material; in winter, 1.5 kilograms of fine material should be added in December to restore the sensation to 80%; by the end of February next year, it should be added to 2 kilograms to lay the foundation for oysters. Male deer concentrate feeds 50% of the male deer. The adult female deer from the August 20 to the 15th before the start of breeding on the 15th before the implementation of short-term excellent feeding, because the doe during lactation consume a lot of milk, body weight loss. The full-price feed must be given during the breeding period, and the female deer must reach 90% of its lyrics before it can ovulate. But the female deer's overweight is not conducive to breeding. In this period, the main feed is fresh sorghum, green and green leaves, carrots, and barley corn. It is advisable to feed 1.5 kilograms of condiments per day, 4 times per day and night, and green feeds should be fed day and night. In this way, the female deer can start estrus on September 15 and the estrus cycle is usually about 16 days. From the beginning of breeding on September 15 to the end of breeding on November 10, a total of 56 days, there are about 3.5 estrus cycles and at least 2 estrus cycles. According to 75% of the first-term quasi-children and 70% of the second-term quasi-children, the total artificial birth rate can reach 90%. In addition to the four maternal breeding deer feeding, the green feed is free to eat day and night. From the end of breeding on November 10 to the end of May in the following year, the deer will be pregnant. Tianshan red deer is 246 days and 4 days, while Dongtian or Dongta hybrid deer is 243 days and 4 days, and mother deer is 2295 days. Doe must supply calcium, phosphorus, copper, iodine, selenium, manganese and other trace elements during pregnancy, otherwise it is easy to cause dystocia and placental clothing is not lower. When vitamins, especially vitamin A and vitamin E, are insufficient, the placental epidermal cells become keratinized and necrotic. Therefore, additives, calcium hydrogen phosphate, and carrots must be supplemented. During pregnancy, green fodder should be the mainstay, but in the winter, the north has a icing period of more than half a year, and there is a serious lack of green fodder. Special attention should be paid to it. During pregnancy, the body material metabolism of the doe begins to change, and the nutritional needs of the doe need to increase significantly, especially in the later stages of pregnancy. This is mainly due to the increased metabolism of the thyroid gland and pituitary gland, and the maternal supply of fetal nutrients is gradually increasing. Deer metabolism can increase by 10% to 15% in the early pregnancy and reach 30% in the late pregnancy. However, pregnant doe has stronger ability to deposit nutrients than empty doe. This phenomenon is called "pregnancy anabolism, and its energy and protein utilization rate increase by 18% and 13% respectively, but it will be higher in late pregnancy. This requires pregnant doe to implement "restricted feeding." Only one-sided emphasis on how fast the fetus grows, it will increase nutrition, it is wrong, doing so will cause the deer to be overweight, but also cause weak and abnormal fetus Difficult to produce, but not too thin, too thin will make the fetus light weight, less breastmilk after birth, late pregnancy should protect the 80% pimple appropriate in the early pregnancy (October to March next year) : Red deer 1 ~ 1.25 kg; late pregnancy (ie, April - May) should be 1.25 ~ 1.5 kg, 6 ~ August breast-feeding period should be given to 2.0 ~ 2.5 kg.Sika deer is appropriate for 50%.
