Résumé partiel
The wool of sheep is one of its skin derivatives of sheep,people began to use wool to make all kinds of textiles for daily life as early as hundreds of years ago,which provided indispensable living materials for the people of the society at that time.Up to now,wool still plays a very important role in the field of textile production,since the Industrial Revolution,it has been the goal of sheep breeders to improve wool yield and wool quality.Since modern times,fine wool sheep and semi-fine wool sheep which provide high quality raw materials for the world wool spinning industry have been bred on the basis of coarse wool sheep,the Mongolian sheep distributed in the desert area of northwest China is a representative breed of Chinese coarse wool,and the heterogeneous coat with medullary wool and unmyelinated wool is the typical feature of the breed,Qianhua Mutton Merino bred in the agro-pastoral ecotone in northeast China is a fine wool breed with both meat and wool,and the homogeneous coat composed of unmyelinated wool is also a typical feature of the breed.Therefore,this study compares the physical and chemical properties of wool quality of Mongolian sheep distributed in Alashan area of Inner Mongolia with Qianhua Mutton Merino in Northeast Songnen Plain,and reveals the differences of wool production performance and wool quality between breeds.It will guide the improvement of local sheep quality and provide theoretical support for the popularization and application of Qianhua Mutton Merino in the western region of Inner Mongolia.At the same time,it also provides a technical basis for the cultivation of new varieties,determination of economic character indexes and feeding management
