The feeding technique of Fructus ostreatus

Young roe deer refers to the young roe deer weaned at the age of 2 months to 6 months at the end of the year. Roe deer are generally weaned at 2 months of age, and the weaning time is usually in August. Just left the mother roe deer lamb, often nostalgic for the mother roe deer and uneasy, spirit and appetite are affected, so breeders should be patient care, careful feeding, often call into the circle, with twigs and leaves and other food to attract close to the roe lamb, caress and care, so that roe deer affinity, generally 3rel 5 days later can return to normal, young roe deer plasticity, so to carefully train and teach, to lay a good foundation for future feeding and management.

The newly weaned lambs have poor feeding ability and cling to the milk of the mother roe deer. When raising them, they should choose green feed that is fresh, easy to digest, palatable and nutritious. In the first week of weaning, according to the ration of lactation, the concentrate gradually increased from 80g / only to 100g / pig. The mixed grass meal feed was mainly composed of all kinds of green fodder. After mixing with concentrate at the ratio of 1:1, the mixed grass meal was fed 4 times a day, and the leftovers were cleared after 2 hours.

From the second week of weaning, the ratio of diet should be adjusted to improve the quality of diet. In the concentrate, 35% of peanut cakes, 15% of fried soybeans, 25% of corn, 15% of wheat bran and 3 grams of bone meal were gradually increased from 100 grams to 300 grams (early December diet). The succulent feed such as carrots can be added to the mixed feed, and dried leaves are added twice a day, with a small amount of surplus each time.

The development of breeding roe deer is relatively mature, which should be based on roughage to exercise the rough feeding resistance of roe deer, which requires good feed quality and many varieties. From January to April, it is mainly dried leaves and grass powder, and the concentrate is still 300 grams per animal. From April to August, it is mainly green feed, supplemented by grass powder, and the concentrate remains unchanged. Because the roe deer is in an important period of sexual development and physical growth, the diet should be at full price to ensure that it is well fed.

Young roe deer experience a cold winter for the first time after birth, and are in a period of vigorous growth and development, and their cold resistance is worse than that of adults. We should pay attention to preparing enough dry clean bedding grass, close the windows on the north side of the shed, and prepare for cold overwinter. let roe deer live in a warm shelter from the wind and the sun for the winter. Roe deer have the habit of lying down and defecating. You should clean and dry the bedding grass every day to keep the circle clean, dry and hygienic. Drinking water is best with rubber buckets, not easy to freeze, buckets should be placed in a corner of the shed, the northern winter temperature is too low, can also provide clean snow or clean ice for roe deer to lick instead of water, roe deer do not need to drink warm water.

The small number of roe deer raised in the farm yard can also let the roe lambs live with the mother roe deer, naturally weaned, the mother and offspring will eat together, and the young roe deer will also grow healthily. Attention should be paid to improving the quality of diet and taking care of the nutritional needs of young roe deer. Young roe deer can be raised and managed according to the same requirements as adult roe deer after 14 months of age.

The feeding and management of male roe deer is the key to the success or failure of domestic roe deer breeding. Male roe deer species spend 70% of their time at rest every year, the time of estrus is very short, and the mating period is only less than a month, which is often ignored by breeders. The breeding preparation period of male roe deer is from early July to August 25 every year. Male roe deer should not be too fat or too thin, but should reach the upper-middle body condition. Therefore, during the preparation period, the dietary protein level should be increased, the proportion of cake and meal should be increased, the protein feed should account for 50% 60% of the dietary concentrate, and a variety of green fodder with high nutritional value and good palatability should be selected for feeding. In particular, branch and leaf feed, green feed rich in vitamin E (such as rosin grass) should reach more than 60% of the diet green feed. In the breeding preparation period, the male roe deer should be raised in a large circle with a spacious sports ground, let the male roe deer run in the sports ground several times a day, do not be kept in a small circle, there is no room for exercise. The male roe deer who are overweight should appropriately reduce the total amount of diet, especially the feed varieties with high fat content, which can be given less or not, and increase the amount of exercise every day, so that the breeders can drive the male roe deer 3 times a day. For the male roe deer who are too thin, they should choose the feed with good palatability and improve the dietary nutrition level to promote the male roe deer to gain fat. According to the dietary level, if vitamin E is deficient, animal vitamin E should be added to the concentrate 30ml 40mg / day. For unsawed male roe deer, if you often top people, the antler can be sawed off.

The mating period of roe deer is from August 26 to September 25. Due to sexual impulse, male roe deer often suffer from decreased appetite, reduced food intake, sometimes fighting for their mothers, and high energy consumption. Feeding management should be strengthened and full-price feed should be provided. the dietary nutrition level should be the highest in the whole year, and protein feed should account for 60%, 70%, and concentrate should be increased to 400, 500 grams per animal. The green feed should be of the best quality, high nutritional value and good palatability, so as to increase the appetite of male roe deer, increase food intake and supplement physical exertion in time. During the breeding period, the male roe deer likes to eat spicy and sweet green feed, which can be fed with soybean highland barley, barley malt, spring onions, elm, mulberry leaves, alfalfa, grain amaranth, rosin grass and so on. During the mating period, we should pay attention to control the drinking water of the male roe deer, and do not let the male roe deer drink water when it is not calm after fighting and mating. Male roe deer should not drink water for half an hour before and after mating. Drinking water during excessive wheezing can easily cause casualties or loss of breeding ability.
