Shearing and physical and mechanical properties of different gimmers’ wool of genetic group of the North meat-and-wool breeds

Abstract

The experiments helped to determine that by shearing of greasy wool of thoroughbred gimmers they give way to the local crossbred animal of group II by 2.2 %, and group III gimmers - by 4.3 %, while the difference was unreliable. In washed fiber difference in favor of the local gimmers of II and III groups accounted for, respectively, 4.0-16.0 %. Crossbred gimmers of II and III group by natural length prevailed over the gimmers of control group by 7.5-8.9 %, the benefit of the animals of group II was reliable, and by real length the local crossbred animals of groups II and III significantly prevailed over the gimmers of group I by 5.5 and 8.8 %. The fineness of wool from crossbred animals was mostly 48-50 quality, and peers in the control group - 56-58 quality. The greatest strength of wool fibers was peculiar with the local gimmers of II and III groups, exceeding their purebred contemporaries, respectively, by 2.1 and 6.4 % (P <0.95).
