How to choose a deer
It is best to choose a species of male deer before buying it in the season of antler growth. At this time, the antler is big or small, good or bad, at a glance. If the antler has been sawed off, it must look like. The head is big, the eyes are god, and the height is right.
The deer in the same deer farm eats the same feed. Deer, who loves to eat and has strong digestion and looks fat, is the ideal choice. In addition, the better the deer resistance to roughage, the easier it is to feed. Crude feed can be used to test their ability to eat.
The deer does not see good or bad. The deer of the same age chooses a big one and goes back and chooses, eliminating the bad ones in time.
Second, the deer breeding technology
1. Feeding the male deer during the velvet period: The deer's velvet period coincides with the spring and summer season. The deer needs a lot of protein, inorganic salt and vitamins. In order to meet the nutritional needs of male deer, it is necessary not only to supply a large amount of concentrated feed and green feed, but also to improve the quality and palatability of the diet and increase the proportion of soybean cake and legume seeds in the concentrate feed. However, seeds with high oil content, such as soybeans, should not be fed excessively and should be cooked. In order to increase the digestibility of soybean seeds and their nutritional value, soybeans can be ground into pulp and mixed with concentrates. In addition, sufficient grass, green foliage, and high-quality silage should be provided during the velvet period.
The concentrate in the diet should be composed of a variety of feeds, among which 40%-55% should be bean cake, 30%-40% should be cereal seed, and 10%-20% should be cereal. The feed amount of the concentrate is: 1.8-2.0 kilograms of male deer per day, 1.6-2.0 kilograms of male deer produced, and 1.5-1.8 kilograms of head sawed to four saw plum blossoms.
During the antler period, the house-fed male deer should be fed 3 times a day and night, and each interval should be extended as much as possible. Each time you need to feed the concentrate, feed the coarse material. It is necessary to be cautious and slow to increase the amount of concentrate in order to maintain its strong appetite and prevent “top loading†due to excessive feeding. While increasing the fine material, it is necessary to supply enough high-quality green roughage. From March to June, silages can be fed twice a day, dry roughages can be delivered once a day, and green feeds and dry roughages can be fed twice a day in June and August. The grazing male deer grazing once a day in the afternoon and afternoon, and should feed a proper amount of concentrate feed each time he returns to herd. In addition, the water supply must be adequate during the antler period, and sufficient and clean drinking water should be available at any time in the sink. At the same time, salt must be supplemented. Generally, 25 grams of sika deer are bred per day and 25 grams of deer are bred. In addition to directly adding salt to the concentrate, salt must be provided, and a certain amount of salt or salt-containing minerals should be placed in the salt tank for about 7 days.
2. Feeding for male deer breeding: The deer breeding period is from late September to mid-November. During this period, the deer’s sexual urges were strong, the appetite dropped sharply, and the contested hits were severe. Therefore, physical exertion was greater. It has been determined that, under good husbandry and management conditions, adult male deer weights decreased by an average of 18.1% during the breeding period. The breeding male deer that participated in breeding had four doe every day, and the body weight dropped by about 20% within half a month. Since not all male deer are involved in breeding, this period should be treated differently for male deer and non-deer male deer.
For the male deer, it is required to maintain the sensation of the upper middle class, which is strong, lively, energetic, and has a strong sexual desire. Therefore, this period should be strengthened for feeding. When the rations are matched, green and succulent feedstuffs such as silage cornstalks, melons, carrots, radishes, green onions, and sugar beets with strong palatability, more sugar, vitamins, and trace elements should be selected. Good quality dry roughage. The concentrated feed must be made from bean cakes, corn, barley, and sorghum. It requires sufficient energy, rich protein, and full nutrition. Feeding amount of concentrate feed: 1.0-1.4 kilograms for plum blossoms. For non-professional male deer, try to control public opinion, reduce sexual desire, reduce fighting, avoid injury and death, and prepare for safe wintering. For this reason, before the breeding period comes, according to the deer's lyrical condition and the quality of the roughage, etc., the amount of concentrate feed should be appropriately reduced, and if necessary, feed for a certain period of time should be stopped, but it is necessary to ensure the supply of a large amount of high quality dry roughage and green feed. Whether it is to reduce the amount of concentrate feed or stop feeding concentrates, it is necessary to ensure that there is a healthy body condition and a certain degree of lyrical conditions, so as to ensure that they safely pass winter and do not affect the production in the coming year. The average non-breeding male deer concentrate feeds 0.5-0.8 kg per day.
3. Feeding the male deer during wintering period: The wintering period of the deer includes the two stages of breeding recovery period and early velvet period. This period is between mid-November and the end of March of the following year, when it is winter and early spring. 1 Breeding during breeding period: After two months of breeding, male deer weighed significantly, the body was thin, the stomach volume was significantly reduced, and the stomach contracted. Non-mating male deer weights will also decrease. The physiological characteristics of male deer during this period are: gradual decline in sexual activity, increase in appetite and digestive function, and greater consumption of heat energy. According to this feature, in the ration of the diet, it is required to gradually increase the volume of diet and increase the proportion of thermal energy feed. The diet should be based on roughage, supplemented by concentrated feed, and must also supply a certain amount of protein feed or non-protein feed to meet the needs of microbial growth and reproduction in the rumen. In concentrate feed, protein feed such as bean cake or soybean meal is appropriate for about 20%, and condiment feed is 0.8-1.2 kg for male deer. 2 Feeding of early velvet: During this period, deer sex activities stopped, appetite and digestive function were completely normal, and nutrients were stored for oysters. The diet should be based on dry roughage and corn silage, supplemented by concentrate feed. The ratio of protein feed should be gradually increased in the ratio of concentrate feed, and 20%-25% of soybean meal should be occupied. The amount of concentrate feed also increased compared with the recovery period, and the amount of feed deer for each sika deer was 1.2-1.5 kg per day. The male deer feeds the concentrate 2 times during the day, feeds the coarse material 2-3 times, and feeds 1 roughage at night.
In the wintering period, dry forage and silage are generally used, and some silages in the deer farms account for a large proportion. It is necessary to prevent the normal reproduction of the rumen microorganisms from being destroyed due to excessive ruminal acidity caused by long-term feeding of silage. Therefore, it is necessary to regularly add some sodium bicarbonate in the concentrate feed to neutralize the excess acid in the rumen and maintain the normal hydrogen ion concentration in the rumen.
