Domestication and Crossbreeding of Wild Goats

The wild goat is a wild and precious animal that is widely distributed in mountainous areas in the north and south of China. Its high lean meat, strong adaptability, strong game. The writer now introduces the experience of domestication, hybridization and breeding of special breeding farms in South China for many years to the readers. First, the construction site requires the choice of sitting south to the north, the area according to the amount of domesticated (about 0.8 mu per goat), built around a wall more than two meters high, loaded with iron gates, the field to plant some deciduous fruit trees and the four seasons Green grass hairy grasses are planted with wild grasses (such as wild hemp, bird prickly vines, and four-season vines) eaten by wild goats. However, the planted saplings and weeds should not be too tall, and the row spacing should not be too close to the plant spacing to prevent obstructing observation. In the south of the wall, a shed of 2 to 2 general homes is built, covered with a awning, and no iron gates are installed. Let the wild sheep come and go freely, and build 1 or 2 shallow pools in the south of the circle to allow the wild sheep to drink water automatically. Second, domestication and breeding Male wild sheep that are captured in the wild or bought back from the market are first put into a wooden bar made of square wood (the wooden ring is 1.5 meters long, 1 meter wide and 80 cm high) and domesticated for several days. Bring it into contact with people. When the breeder reaches out and touches the wooden circle, the wild sheep will not jump. Then the wild sheep will be put into the domestication field from the wooden circle, and the animal shall be injected once with the livestock vaccine before entering the domestic breeding ground. Triple seedlings, then pull out the left and right teeth, and then use the "Xiao Ling" according to the instructions mixed with water and wipe the body. Selecting domesticated wild sheep generally requires young sheep of small age (according to the summary experience, the wild sheep has a growth cycle of two months and a body weight of 5 kg to 6 kg), and the plasticity is strong. Since the domesticated wild sheep began to fear others for a period of time, it was based on the growth characteristics of the pure wild sheep that they put several yellow sheep of the same weight and similar coat color, but they could not be the same sex. For example, the wild sheep of the male must be placed in the female only. Yellow sheep, in order to prevent the fight in the domestic farmyard, while avoiding snatching, the use of polyculture can enable wild sheep and yellow sheep to feed together. Serve the forage twice a day and do more in the evening, about 60%. After the wild sheep have contacted each other for a period of time and have grown courageously, the rearing staff did not run away and even dared to contact with the breeder. At this time, the yellow sheep that was put into the farm were driven out of the domestication field for raising, and the sheep were eaten by the wild sheep. Weeds and crops are the same as yellow sheep (ie, sweet potato vines, yellow bean leaves, and wheat seedlings). They are all green feed for sheep, but the feeds for these crops are best cut into short sections and supplied with 0.5 iodized salt to change wildness. . Third, the use of hybrid When the domesticated male wild sheep feeding 2 months to 3 months, the general body weight up to 10 kg to 15 kg, then showed sexual behavior. The estrus ewes can be placed in the domestication field to allow the wild sheep to mate with the yellow sheep. But what time is suitable for mating, according to the experience of the field technicians: the ewes of the first estrus should not be mated for the first time, and should be put into mating when the second estrus occurs. The ewes that have already been born can be bred when the ewes are in heat, and the mating time is preferably in the morning. It is not appropriate to mate at night and mate twice, each separated by 1 hour to 1 and a half hours. After mating, they will drive out of the domestication field in time for raising. At the same time, they will feed the male wild sheep with some fine feed or pond water, so that the male wild sheep can be restored to health as soon as possible. Next, a single ram can mate 3 to 5 ewes each day. The rams of the wild goat cannot be mated with other sheep (especially black and white sheep or local variegated sheep), and the one-way hybrid (ie, special sheep) produced by the mating yellow sheep can be used as a sheep, but it is not appropriate. Cross-breeding with the binary hybrid sheep to prevent the degradation of the variety. The appearance of special sheep and grazing sheep are similar to that of Nanjiang Yellow Sheep, but its growth is relatively fast. The ewes are usually born at 3, and some are as high as 4. Fourth, the special sheep to keep alive The main concern of professional sheep breeding special sheep is only two ewes tits, how to feed 3 sheep, the author again according to the field experience points. (1)Preparation for farrowing The cleaning, disinfection, and padding of the plant and wood ash (winter) should be done 7 days to 10 days before the birth. The disinfection can use 2% lime water to wash the sheds, cushions and pads. The grass depends on the climate, and the cold in the north must be insulated with plastic sheets. (2) Disposal of dystocia There are fewer symptoms of dystocia in primiparous ewes, but it is difficult to avoid them. When the ewe flow out of the amniotic fluid, but the fetus is not seen for a long time, or the fetus is embedded in the hole of birth and death, it is a symptom of dystocia. When dystocia is found and the opening of the cervix is ​​confirmed, oxytocin can be produced. Intramuscular injection of pituitrin 0.2ml to 0.5ml, or intramuscular bolus of 2ml to 3ml. If the fetus is still not seen after 2 hours to 3 hours, artificial midwifery can be performed. The method is to disinfect the vulva first with a disinfectant solution, then lubricate the vagina with glycerin and pull the fetus out. (3) Care of Aries The Aries are dependent on the growth of the mother's milk, and ensuring the survival rate of the Aries is the most important point. Generally, the hair around the postpartum ewe's nipples is pulled out so that the sheep can suck. If there are 3 or 4 litters in the ewes, or if there is no such thing as postpartum milk, the decision should be made promptly. The lambs can be handed over to other ewes for fostering, and the foster mothers must be supplemented with milk for breeding. Enough milk. According to the technicians in the field, the ewes were kept in the pens, the deceased sheep were painted with the feces of the sheep, and then the sheep were put into the pens, so that the deceased ewes will enter the sheep in the circle. Eat milk. Adolescents develop rapidly, and generally eat 3 to 4 weeks of milk to start eating grass. At this time, sheep can be supplemented with easily digestible concentrates. For example, if a ewes produce 3 to 4 ewes in a single birth, in addition to replenishing the ewes' concentrates within 3 weeks to 4 weeks, the sheep can be artificially fed in batches, even though the lean ewes eat less milk and leave the milk early. Weak and small to eat more milk, weaning.
