Improved Current Situation And Development Strategies Of The Amelioration Of Yongchang County Sheep Varieites

Objective: Yongchang county is a large county of key of sheep, sheep industry development inYongchang county is the breeding utilization levels, research on current situation and Countermeasuresof improved varieties, for protection, the development of Yongchang County sheep production and thedevelopment of livestock and poultry breeds resource utilization, planning and rational allocation ofvarious resources to provide practical information and on the basis of. Methods: the subjects takestatistics as the theoretical basis, to the Yongchang County sheep breeding quantity, variety resources,hybrid offspring production effect was studied, on the basis of this, by using mathematical modelingmethods, established a model population of sheep and sheep herds. Results: the Yongchang Countysheep breed resource distribution formed in Xinchengzi Town, Hongshanyao Township, Jiaojiazhuangtownship as a representative of traditional grassland sheep area and as a source of water, Zhuwangpu asthe representative of the agricultural straw sheep area pattern. Population of sheep and sheep herdsoptimal model respectively for y=0.0205x~3-0.3523x~2+6.1652x+26.082(R~2=0.8725) and y=0.0125x~3-0.1261x~2+4.0505x+21.793(R2=0.9086). Conclusion: Yongchang County sheep herds ofsheep and time series model, can provide the decision-making basis for the development of animalhusbandry. At the same time, in view of the sheep breeding varieties according to market change moreto high yield, high-quality, dedicated to change direction, which has the advantages of long service life,cold-resistant, resistant to crude feed, disease resistance and other unique traits of local sheep varietygroups is shrinking fast, existence of sheep breeds only focus on the benefit, ignoring the problem ofadaptability, the breeding sheep breeding for both quality and benefit, put forward the countermeasuresto promote the use of improved varieties of sheep.
