1. Division of production period
According to the production cycle and breeding characteristics of the deer, the artificial production process of the deer is divided into the breeding period (September to November 15th), pregnancy (November to May of the following year), and the littering period ( From May to August, of course, the division of each period should not be one size fits all.
2. Diets for adult doe
The corresponding rations should be rationed according to different production periods. In particular, the amount and quality of the diet should be paid attention to in the late gestation period and the lactation period. Therefore, the deer should not only ensure its own nutritional needs, but also have to meet the development of the fetus and lactation deer. Nutrition. Diets for each period of the doe are shown in Table 7-4.
3. Feeding management technology
(1) After the females of the breeding period are weaned, they must reach a medium level by the middle of September, so as to ensure normal estrus and ovulation. 1 This period should be provided with a certain amount of protein and rich vitamin feeds, such as bean cakes, barley soy, cut whole corn, and carrots, radishes and so on.
2 Weed out the female deer of infertility, old age, offspring and evil spirits, and then establish breeding nucleus groups and general production groups according to their reproductive performance, age, public sentiment and avoidance of kinship. Breeding deer group should not be large, each group of 15 to 18 deer, 11 to 12 red deer.
3Special care should be set up for the mating period. When the deer is found to be estrus, when the male deer cannot be “competentâ€, the estrus’s mate should be immediately transferred to the deer’s breeding house, and the deer of the original deer should be immediately replaced.
4 In order to avoid inbreeding and the pedigree is clear, the mating method of single male and female females should always be adopted. The female deer should not be arbitrarily exchanged. At the same time, it must be ensured that the male deer has a strong ability to breed.
(2) During pregnancy, the nutritional needs of the pregnant doe should be ensured (3 months of late pregnancy, fetal weight gain of 555 grams), first of all to meet the needs of protein, vitamins and minerals. In the early stages of pregnancy, some green fodder, root-like feeds and good-quality roughage should be given. In the late stages of pregnancy, rough fodder is required to have good palatability, good quality, and small size. Feeding times 3 times a day, including 1 at night. Feed should be strictly prevented from rancidity, freezing, and drinking warm water. At the same time, during the gestation period, they must prevent the deer from being disturbed and drove the deer. It is forbidden to have snow and ice on the ground.
(3) The maternal deer during lactation and lactation needs large amounts of protein, fat, minerals, and vitamins A, D and other nutrients. The plum doe needs about 700 milliliters of milk every day. Therefore, it is necessary to strengthen feeding management so as to ensure The deer grows well and prepares for the normal estrus of the doe after weaning.
1 After giving birth to the deer, the volume and function of the digestive tract are significantly enhanced, and the amount of drinking water is also large. Therefore, it is necessary to ensure sufficient amount and quality of green fodder, and it is better to feed the whole plant with spikes later.
2 concentrate feed is best fed to millet porridge, or fed with soy milk mixed concentrates, can increase lactation of female deer, and then promote rapid growth and development of deer.
3 To keep the deer circle clean and hygienic. Before giving birth, the shed should be completely cleaned, thoroughly disinfected, and often disinfected afterwards.
4 During the farrowing period, special persons should be set up to watch the circle to prevent the evil deer from licking the anus, bite the tail, and beat the deer. Abandoned puppies are looking for nanny deer or taking artificial breastfeeding.
5 Keep the calving circle quiet and refuse to visit.
6 The domestication of the deer must be done during the lactation to facilitate future management.
