Adult deer winter feeding management points

From early November to late March of the second year, it is in the winter season. The deer is neither equipped nor bred. Non-production season. Due to depletion of physical energy during the breeding period and seasonal weight loss, the deer has a relatively weak constitution. During the winter period, the intake of the deer increases, and the constitution recovers quickly. For the elderly and sick deer to prevent the death of winter consumption, should consider increasing nutrition, while increasing nutrition in the early period of velvet can also be removed in advance to lay the foundation for oyster. 1. Gradually restore nutrition and ensure safe wintering. After the deer arrived in December, her libido gradually decreased, her appetite gradually increased. Due to the winter, her energy consumption was also large. The deer field should gradually increase the supplementation of the concentrate material, and the adult deer should be added in an amount of 1.1-1.4 kilograms. 2.0-2.5 kg, and sufficient roughage should be provided at the same time. The lack of green roughage in winter can be fed with leaves, straw, silage, etc. At the same time, drinking water should be guaranteed, preferably warm water. Even if the young male deer can safely overwinter even if the nutrition is not too good, but the old weak deer should ensure that there is a corresponding supply of fine material, otherwise it will easily lead to failure and death. In the early period of velvet, it is also necessary to increase the feed amount of the concentrate to prepare the deer's offspring. 2, adjust the deer, the appropriate elimination of the old weak and low-yield deer. Winter is the season to test the deer's body condition. The deer field should properly dispose of the old and weak and the deer whose production antler is too low according to the actual situation. The deer should have separate groups to prevent the old and weak deer from eating. Death to feed occurs. 3, moisture insulation, maintain health.

Second, doe gestation period of feeding and management from December to April of the second year, is the deer gestation and embryo in the maternal uterus growth and development of mature fetus. In addition to maintaining their own physical needs during this period, the deer must also supply various nutrients to the fetus so that the fetus can grow and develop healthily. 1. Strengthen nutrition in phases. In the first trimester of pregnancy, the absolute weight gain of the fetus is small, but the organ differentiation and development is fast. During this period, the nutritional needs of the deer mainly focus on quality. In the production, a variety of feed ingredients should be used for feed preparation, balanced deployment, energy, protein, Mineral elements and vitamin nutrition can meet the needs of doe and fetus. In late pregnancy, fetal weight gain increases, and the mother's own volume is also strengthened. During this period, physical condiments should be ensured and the amount of feed should be increased. At the same time, the volume of the diet should be taken into consideration to prevent excessive grazing due to excessive dietary volume. Press the fetus. Of course, the doe at the end of pregnancy should also maintain a suitable body condition to prevent over-fertilization and cause dystocia.
