After the deer and doe have been mated from September to November each year, the deer enters the winter rest period. Deer in winter
Although not producing larvae, it is closely related to the velvet and calving of the following year. If you do not provide good feeding during the winter
Management conditions will not have high summer yields. Therefore, it is necessary to improve the deer’s winter feeding management to improve the deer’s life.
An important part of the successful winterization of economic benefits and safety. For this reason, according to the current experience and practices of deer conservation around the country,
The following are the highlights of several breeding and management techniques for deer in the winter.
1 Pay attention to the insulation work of the deer
Although the deer is not afraid of cold, the cold environment will consume a lot of heat energy in the deer. To increase body heat to keep warm,
As a result, the deer increased its food intake, causing a waste of feed and an increase in production costs. Young deer and bred deer to the environment
The degree of response is more sensitive, if the winter is too cold inside, it will not only affect the growth and development of the deer, but also lead to
Deer have a cold, pneumonia, and some also cause death. At present, the use of warm circles to raise cattle and raise pigs to improve health
The method of producing benefits has been accepted by people. Similarly, deer feeding in warm winter is also an important technology.
Measures. At present, the commonly used insulation measures are: (1) In the winter, sawdust can be laid on the ground in the housing as a pad.
Material, its advantage is that it can not only keep warm, but also can absorb manure, and it is easy to do a good job in environmental sanitation. (2) Blocking the deer house
Wall wind hole to prevent thief wind invasion. (3) Snow should be cleared inside and outside the house immediately after snowing in winter.
Temperature can also prevent the deer from slipping and causing a fracture. (4) Warm drinking water should be provided in winter, and in the evening,
The remaining water is released to prevent the deer from drinking ice water and freezing the sink. (5) Farmers raise deer and can hang grass curtains and cloths
Curtains, plastic sheets, etc. are used for insulation. It is also possible to put several bundles of firewood at the shepherd's gate at night and take it out during the day.
2 Perform manual supplemental lighting
(1) The basis of fill light. The growth of live weight of deer is faster in spring and summer than in autumn and winter (the slowest growth in winter).
This natural growth rule extends the deer's maturation time and delays the deer's antler time. If it is a meat deer,
The annual supply of venison is out of balance, that is, there are sufficient meat sources in spring and summer and there is a shortage of meat sources in autumn and winter. The seasonal growth of deer is
Naturally formed, intrinsic, has nothing to do with simple feed supply but is related to the length of light. According to research findings,
Continuous light for 16 hours on a night in winter, followed by 8 hours of darkness, with light intensity of 250-300 lx
(Lux), such a regular treatment for six weeks will enable the deer to accelerate growth in winter and increase feed intake.
Accelerate weight gain.
(2) The necessity of filling light. In the temperate zone of China, most regions have four distinct seasons, and the short winter sunshine is long.
Up to 3 to 4 months. To supplement the light with artificial light, the captive deer has a continuous 16 hours of light.
(3) The method of supplementing light. Any kind of electric light can be used as a light source, generally an incandescent light bulb
Appropriately, to be measured at a height of 250 to 300 lx at a height of 1 m above the ground (not directly below the light source)
can. Normally the lights are turned on after the sun goes down and artificial lighting is added. When natural light (daylight) time is added to light
Turn off the lights when the time is up to 16 hours. If it is overcast or overcast, the light intensity needs to be replaced with artificial light all day.

(4) The effect of supplementing artificial light: Artificial light supplements have been used, and many deer farms in China have seen obvious
effect. According to data reports, the winter light-up test of the Xiaogong Red Deer in that year proved that in the 6-week old period,
The daily weight gain of the test group was 330 g. The control group without artificial light supplement was about 152 g. The test group was 2.2 of the control group.
Times. At the same time, the feed intake of the deer in the experimental group increased, the feed utilization rate was improved, the deer’s coat was bright, and the antler time was again
5 to 10 days in advance. Artificial deer supplementation of the deer in winter is beneficial to deer and velvet deer, especially for deer breeding.
The significance is greater. It can promote deer maturity, produce velvet in advance, and increase economic efficiency.
3 Feeding high-quality feed
After artificially supplementing the light, because the deer's feed intake increases, for this purpose, the deer must provide a sufficient amount of feed.
This can fully tap the potential of artificial light to achieve the purpose of improving production performance. Some deer farms in northern China
In winter, corn stalks and soybean stalk silage are used to feed deer, which not only fails to meet the demand for feed after supplementing light, but also occurs easily.
Vitamin deficiency. Therefore, it is best to add high-quality feed such as loquat, carrot, or beet to feed.
Deer's growth and nutrient needs for body metabolism.
