Abstract
The wool yield records of Awassi sheep maintained at the Livestock Experiment Station, Bahadurnagar, Okara during 1965-X4 were used to determine the heritability of wool yield. The mean Wool yield at first, second and third shearings and the combined yield of three shearings and./i[e time yield in single born ewes were 2.79 ± 0.048, 2.93 ± 0.Q15, 2.91 ± 0.066,K43 ± O.UO and 10.47 ± 0.290 kg, respectively. Similarly, wool yield at first and second shcarings and life time yield was 2.82 ± 0.073, 2.61 ± 0.084 and 8.93 ± 0.410 kg, respectively in twin born ewes. The heritability estimates of wool yield at first, second and third shearings and the combined yield of three shearings and life time yield in single born ewes was 0.524 ± 0.291, 0.369 ± 0.260, 0.280 ± 0.28, 0.068 ± 0.02 and 0.632 ± 0310, respectively, The heritability at first and second shearings and life time yield was 0.904 ± 0.65, O.22X± 0.44 and 0.512 ± 0.54, respectively in twin born ewes.
