Breeding Technology of Dongshan Sheep

Hainan East Goat is mainly produced in Dongshanling, Wanning, Hainan. It is referred to as "East Goat" by locals for short. It is famous for its high-quality mutton inside and outside the island. Together with Jiaji Duck, he Le Crab and Wenchang Chicken, it is called the four famous dishes in Hainan. In 2009, it was listed by the Hainan Provincial Department of Agriculture as the first batch of livestock and poultry genetic resources protection breeds. Let's take a look at Hainan Dongyang breeding technology.

Breeding advantages of East Goat

The main results are as follows: 1. The investment is relatively small: the East Goat is a herbivore and a grain-saving animal husbandry, and there is no problem of competing for food with people and animals.

2. Strong fecundity: East goats are in estrus in four seasons. Ewes can be conceived at the age of 6 months, giving birth to 1-2 births a year, with a lambing rate of 150-200%, and a twin lamb rate of up to 80%.

3. It has good adaptability. Dongshan sheep can adapt to both grazing and house feeding, especially to hot and humid conditions, so it is suitable for breeding in the south of China.

4. Dual use of meat and medicine: East goat not only has good meat use, but also has a very high content of sheep placenta, which is a better raw material for extracting sheep placenta.

Breeding techniques of East Goat

1. Build a sheep house: the sheep house should be sunny against the wind, warm in winter and cool in summer. Each sheep covers an area of 1 square meter, and the playground outside the sheep barn is 3 times the area of the sheep barn. The playground is equipped with feeding trough, grass rack, drinking trough and so on. Fodder storeroom, silage cellar and other facilities will be built near the sheep house. At the same time, it is necessary to install feed processing machinery and straw cutters and other equipment for processing coarse fodder.

2. Sufficient fodder: each sheep raised in the house needs 300 kilograms of straw or hay, 60 kilograms of succulent feed and 60 kilograms of concentrate per year. To open up a wide range of feed sources, the straw of various crops, such as corn straw, rice straw, wheat straw, bean straw, bean beetle, peanut seedlings, sweet potato vines, etc., are good fodder for raising sheep.

3. Scientific feeding: sheep raising should adhere to the principle of feeding roughage mainly and supplementing fine fodder. To all kinds of crop straw, hay, silage, ammoniated feed, appropriate supplementary feeding of corn, cakes and other concentrate feed. The feeding method of coarse before fine should be adopted, first feeding straw or hay, then feeding green grass or silage, and finally feeding fine feed.

4. Careful management: do a good job in protecting the fetus of pregnant ewes, do not feed moldy and deteriorated frozen feed, and prevent abortion caused by collision and extrusion. Do a good job of drying sheep in summer, "the Beginning of Summer" set up "sheep Kang", often pad dry soil in the house. "the Beginning of Winter" removed the sheep pit, and there will be no more dung in the pen, so as to keep the sheep house warm. Rectify the sheep flock before overwintering and eliminate the sale of old, weak, sick, disabled and infertile sheep, so as to reduce the pressure of house feeding and improve the efficiency of raising sheep.

5, do a good job of reproduction: to achieve centralized breeding, centralized lambing, easy management. The sheep that carry out this breeding can generally start breeding from "the Beginning of Winter" to "Lesser Snow" in early November, and concentrate on producing lambs before and after the "Qingming Festival" in the following year, which is conducive to the survival of lambs. For sheep that carry out frozen semen mating, the mating period can be advanced to the first ten days of October, and ewes that have not yet been conceived after two estrus periods can be mating with a breeder ram.

Disease Prevention and Disinfection of East Goat

1. Environmental disinfection: the environment around the sheep house (including the playground) is regularly disinfected with 2% caustic soda or quicklime once. Around the sheep farm and in the sewage tank, manure pit and sewer outlet, disinfect it with bleach once regularly. Set up a disinfection pool at the gate of the sheep farm and the entrance of the sheep house, and change the disinfectant regularly.

2. Personnel disinfection: when the staff enters the production area, they should change their overalls and work shoes, and be sterilized by ultraviolet radiation for 5 minutes. When visitors enter the site area, they should change their overalls and work shoes, disinfect them by ultraviolet radiation for 5 minutes, abide by the epidemic prevention system and follow the designated route.

3. Sheep house disinfection: after each batch of sheep comes out of the pen, it should be thoroughly cleaned, washed with water and sprayed with disinfectant of the prescribed concentration.

4. Disinfection of appliances: regular disinfection of feeding utensils, disinfection and cleaning of daily appliances before and after use, and disinfection of sheep transport vehicles before and after transportation.

5. Sheep body disinfection: before any contact operation on sheep, such as midwiping, mating, injection treatment, etc., the relevant parts of the sheep should be wiped and disinfected to ensure the health of the sheep.
