Breeding techniques of Black-bone Sheep

Black bone sheep meat is delicious, rich in melanin content, with dual health care functions of nourishing yin and yang. The whole body of black bone sheep is a treasure, which has inestimable value for the deep development of medicine and nutritional health care products.

Grazing Technique of Black Bone Sheep

1. Key points of grazing management in four seasons

① Spring grazing: due to sheep after a long winter and spring withered, sheep fat poor, mouth greedy, easy to greedy and cause diarrhea, or eating poisonous grass poisoning, or grass swelling (rumen gas). Therefore, spring grazing should prevent sheep from "running green"; second, it is necessary to prevent sheep from "bulging belly", often "sheep stop head, put full belly oil; sheep do not stop head, run into thin horse monkey" saying. Spring grazing should be tight, at the beginning of the old grass slope or feed some hay, and then grazing in the grass slope. Spring grass tender, high moisture content, cold in the morning, can not let sheep eat dew grass, otherwise easy to cause diarrhea. In spring, when sheep graze and eat grass, they should feed salt every 5 to 6 days. When feeding, it is good to fry the salt until it is slightly yellow. Add some ground heat-clearing, appetizing foods and essential additives. This can help digestion, increase appetite and supplement nutrition. At the same time, the sheep should be allowed to drink at least once a day.

② Summer grazing: summer climate characteristics are hot, rainstorm, mosquitoes, should do a good job of heatstroke prevention and cooling work. Grazing should pay attention to early and late return, noon hot, to prevent sheep "Za Wo Zi", should let the flock to ventilation, shade rest. When necessary, adequate rest is given in the middle of grazing. At the same time, we should do a good job in mosquito prevention and insect control. Give sheep plenty of water and salt.

③ Autumn grazing: autumn is clear, pasture is rich, and grass seeds are gradually mature, it should be the season of "good sheep grazing in the mountains". Autumn is the breeding season for flocks, grazing, pay attention to the sheep put full, put well, this is not only fattening in winter, winter safety and sheep breeding are also very important.

④ Winter grazing: winter days gradually turn cold, plants begin to wither, and there is rain and snow frost. Grazing, should pay attention to cold, warm, fat, lambs. Winter grazing often in front of the village and sheep pen around let sheep eat some leaves, hay, sunny days let sheep exercise and bask in the sun, pregnant ewes should not turn over the ditch over the mountains. At the same time, to repair the sheep house, known as "circle warm three points fat" said.

2. Organization of sheep

(1) Reasonable organization of sheep can save labor and facilitate the management of sheep. Generally, according to different grazing conditions in different areas, sheep groups are organized according to gender and age.

(2) In the area with large grazing and grassland area, 200~250 breeding ewes, 150~200 castrated fattening rams and 80~100 breeding rams are generally used as a group.

3. There is generally no large area of grassland in agricultural areas, and sheep grazing mostly uses the edge of the land, roadside, woodland and river embankment. Grazing is limited to some extent, and sheep should not be too large. Breeding ewes and breeding ewes are 30~50 in a flock, castrated fattening rams are 20~40 in a flock, and breeding rams are about 10 in a flock.

(4) Pastoral and hilly areas may depend on grazing conditions.

Living Habits of Black-bone Sheep

Black bone sheep have black bone sheep and black bone goat 2 varieties. Black bone sheep has strong adaptability, wide feeding habits, coarse grain tolerance, can eat all kinds of weeds, tree branches and leaves, straw, vine, grass and other coarse feed, the sheep growth and development fast, individual large, adult sheep can reach more than 90 kg. Sexual maturity is early, the first gestation period is 5~6 months old, the estrous cycle is 21 days on average, the gestation period is 148 days on average, each litter is usually 2, and the postpartum estrous period is 20 days on average.

biological properties

The appearance characteristics of black bone sheep are similar to Tibetan sheep, which can be distinguished by careful observation. Black bone sheep body fat, strong disease resistance, coarse feeding tolerance, adaptability, wet, cold, dry climate can adapt, was introduced to Shandong and other places to feed, can grow very well, in better feeding conditions, 6 months old sheep height 55 cm, weight 30-40 kg, lamb survival rate of more than 98%.

variety formation

Black-bone sheep originated from Crossbow Village, Tongdian Town, Lanping County, Yunnan Province. At present, black-bone sheep bred in various provinces and cities in China come from this village. It is a rare species resource unique in the world. Black bone sheep grow in Yuping Mountain Range with an altitude of 1900-2800 meters. The breeding range is 1 township, 2 administrative villages and within 30 kilometers. The local food crops are mainly tartary buckwheat, potato, oat and so on. Grassland vegetation mainly consists of alpine meadow grassland, bamboo, Qinggu shrub, Yunnan pine, thorn chestnut and forest grassland. The water source of the pasture is a spring in the mountain forest. The sheep raised in Lanping are Tibetan short-haired mountain coarse wool sheep. The sheep have long been self-propagating and self-supporting, and rarely exchange breeding sheep with the outside world. In 1999, Yunnan Agricultural University experts went deep into the investigation of the origin of black bone sheep, dissected black bone sheep, and its black bone and black meat characteristics were obvious. In 2001, Science and Technology Department of Yunnan Province instructed Yunnan Agricultural University and Animal Husbandry Bureau of Lanping County to carry out special project research on black bone sheep. The results showed that some genes of Tibetan sheep had mutated and produced new traits under the condition of long-term feeding in special geographical environment, water quality, climate, grassland and forage grass. The black bone and black meat characteristics of black bone sheep were obvious and genetic stability was stable.

Breeding black bone sheep has high economic benefit and low feed cost. Because this breed sheep is rare and precious, the quantity exceeds demand. The price of each sheep varies from 6000 to 18000 yuan, and there is still a price but no goods, the market supply exceeds demand. Breeding black bone sheep has become a new type of short, stable, fast, high-income rich good project.
