The yield of washed fiber and performance indicators in young rams of the taurian type Askanian fine fleece breed

Abstract

Under market conditions, the increase in wool and lamb production should not only increase the livestock number, but also increase its productivity. The significant reserve is also to improve the quality of raw materials produced. The aim of the research was to identify the features of wool and meat productivity in young rams of the Taurian type Askanian fine fleece breed the taking into account an in-depth assessment of the washed fiber yield and subsequent use of the obtained data in the selection-breeding work with sheep. The young rams of the Taurian type Askanian fine fleece breed were used for research. The formed groups were characterized by low, medium and high yield of washed fiber. The results of the studies showed an advantage in all research parameters in young rams with an average yield of washed fiber. Therefore, it is proposed to direct the selection-breeding work to improve live weight and physical and mechanical properties of wool in young rams with high yields of washed fiber (more than 60.1%), which will allow to obtain more profits not only from the wool sale but from the sale of mutton, and to reject lambs with a low washed fiber yield to prevent the transmission of this trait to their offspring
