An evaluation of soft rolling skin as a selection criterion for the genetic improvement of South Australian Merino sheep.

摘要: The consequences of selection for ‘Soft Rolling Skin’ (SRS) were examined in two age groups South Australian Merino ewes which objectively measured and subjectively assessed a wide range skin, fleece body traits. pooled (over groups) heritability SRS score was 0.29. had low to moderate but favourable correlation with fibre diameter, diameter variability, percentage fibres greater than 30um S/P ratio. calculation differentials indicated that the use as criterion (within flock) could provide benefits. achieved similar (negative) an index based approach, it resulted smaller (positive) clean weight. At high intensity negative differential staple strength, whereas did not. Both small generally wool characters. It is concluded approach are not antagonistic often portrayed rural press.
