The division of production time facilitates production management and improves the productivity of deer. According to the production status of male deer, the production period of one year is divided into four periods. Sika deer: early period of velvet (from late January to mid-March), period of velvet (from late March to mid-August), breeding period (mid-August to November 15), and breeding restoration period (November 15~ In mid-January of the following year); Red deer: Early period of velvet (middle of January to mid-February), period of velvet (late February to early August), breeding period (mid-August to early November), and restoration period of breeding (mid-November to early January).
The beginning and end of each period are different because of deer species, geographic location, climatic conditions, deer quality, and feeding technology. If some of the above factors are better, each period may be ahead of schedule, or it may lag behind. .
Diets at different production stages At present, the deer's concentrate diets have little difference in various regions, mainly composed of corn, beans, and bran. The amount of feed in each production period is basically the same, while the roughage is adapted to local conditions. The quality of the concentrate feed should be guaranteed, and carrots and other vitamin feeds should be supplied during the breeding period.
Feeding Management Techniques During the velvet period, a male deer not only needs its own nutrient for survival, but also has to meet the nutrition needed for antler growth. Sika deer saw three antler antler average daily growth of fresh weight 30 grams 5 grams, Northeast Red Deer 1 saw ~ 11 saw pilose antler growing fresh weight 55.3 grams 19.3 grams, therefore, the velvet period must have a higher nutritional level. The results of the study showed that the protein levels in the antler diets of the first and second saw plum blossoms should be 23%, and the best weight gain and velvet for the three sawed deer at 21%. At the same time, the amount of minerals and vitamins should also be guaranteed.
2 Before velvet (Sika deer in late February, red deer in early January), the amount of concentrate should be gradually increased to promote male deer rejuvenation and rejuvenation. When the deer is removed, it should basically be close to the amount of antler. Increase 0.1 kg approximately every 3 days to 5 days or 7 days to 10 days. After sawing the trifoliate orange, the concentrate feed should be reduced to 1/2~1/3 of the original, in order to reduce the public deer's lyrics, so as to reduce the casualties caused by the male deer fighting during the breeding period.
3 The velvet period is a hot summer season and should keep the deer drinking enough water. The amount of water should be 7 kg to 9 kg per head per day, and the red deer should be 15 kg to 20 kg per head per day.
4 Keep an eye on the deer's de-plattering situation and find that when the flower-vein pressure is too late, it should be removed in time. The biting and venomous evil deer should be raised in a single circle in time.
5 During the velvet period, keep the deer's house quiet and refuse to visit. Before the deer enters the velvet period, foreign objects such as nails, iron wires, and wooden piles at the foot of the wall in the pen should be removed to prevent scratching the velvet.
6 After the sawdust velvet is started, the sawn-tailed male deer should be raised in separate groups for management purposes.
During the breeding period, due to the strong deer sex, chasing each other, fighting, squeaking, poor appetite and physical deterioration, the feeding and management during this period should be strengthened. Otherwise, the wintering period is likely to cause death and affect the output of the leap year.
1 The male deer were grouped individually by species, non-species, age, old age, sickness, etc., and then deer and old deer were given excellent feeding.
2 The maturing period of roughage should be selected from palatable, sweet and bitter, high-sugar and high-vitamin feeds. For example, whole plant corn, fresh branches, melons, carrots, radishes, onions, beets, etc. Increase deer feed intake.
3 The breeding period should pay attention to maintaining the relative stability of the male deer group. Deer species are best managed separately in small circles. The deer species that can be exchanged must not be placed in a non-species male deer group. Because of the smell of the deer, they will be subjected to a â€œdeath.â€
4Specialty period should be set up for people to observe the breeding ability of male deer. Once the species deer found to be not "competent" should be exchanged immediately; at the same time, it is necessary to stop the fight between male and female deer.
5 The mating period requires that the house be free of muddy water, and there should be no bricks and stones on the ground.
The overwintering period includes the two stages of breeding restoration period and early velvet period. During the cold season, the deer body not only needs to consume part of the heat to protect the cold, but also needs to restore the physique of the mating period and accumulate â€œpowerâ€ for the antler. Therefore, it is often due to wintering. The period of feeding and management can not keep up, often causing the spring deer to die.
1 From the nutritional point of view, while satisfying the supply of energy feed (grain), gradually increase the protein and vitamin feeds, and promote deer as soon as possible to increase growth and rejuvenation.
2 The number of feedings in winter is 2 times during the day and 1 at night. It is best to feed hot material at night.
3 This period must ensure that enough water is available and warm water is provided.
4 Strengthen the movement of deer feeding deer, drive half an hour each morning and afternoon, drive the deer to exercise only in the house.
5 The house should be kept dry, clean and free of snow. The floor of the house should have enough sedge or dried manure.
6 Strengthen the deer management to prevent the death and death of deer due to fighting. Disadvantaged deer are set aside at any time and fed separately.
7 In this period, the incidence of necrobiotic disease is the highest, and it should be prevented and treated in time.
