WOOLLEN PRODUCTIVITY AND WOOL QUALITY INDICATORS IN THE SEMI-COARSE-WOOLED SHEEP OF ZUGALAY-TYPE AGINSKY BREED

The authors explored wool production and quality of wool of Aginsk zugalay breed sheep of different age and sex in the pedigree-breeding unit of Lenin agricultural cooperative located in Mogoituiskiy district of Trabs-Baikal region. The results obtained show that untrue unwashed wool of medium-wool breed varied ranged from 1.91±0.06 kg in the case of firsts to 3.92±0.07 kg in the case of producers in output of washed wool untrue 74.13-81.81%. The average thickness of rams’ wool is 32.82±1.27 mkm, ewe - 28.39±0.95, ram hogs - 28.21±0.95 and gimmer - 26.60±1.06 mkm when the strength was 10.89; 10.72; 9.21 and 9.00 cH/tex. Zugalay sheep have high concentration of wool, which varies from 66.61 to 81.72%, and rough beard hair (59.10-72.42 mkm). The highest content of wool was observed in young animals. Untrue wool of all sheep in different age and sex groups is 21.40-23.51 mkm (60-64th quality). The length of woolen fibers of the lower tier was 8.20-8.44, beard hair was 14.74-15.04 cm. The highest amount of fat and sweat was observed in servicing sheep and replacement ram hogs (Р˂0,05). The authors found out high correlation between the body weight and washed wool untrue in the sheep of all age and sex groups, especially in young sheep (0.629 in ram hogs and 0.717 in gimmers), as well as between wool thickness and its length (r=0.273-0.668) and between wool thickness and beard hair (r=0.306-0.687).
