| Abstract | ||
| This study was carried out at the Ruminants Researches Station (20 km west of Baghdad) / Office of Agriculture Researches / Ministry of Agriculture, over to estimated of role of cytoplasmic inheritance and maternal effect in some body measurements of Turkish Awassi sheep, over period from 2011 until 2012. The heritability of body length (BL), high at front (HF), heart gather (HG) and circumference of (C ) at birth were 0.40, 0.37, 0.37 and 0.26, at weaning were 0.42, 0.37, 0.39 and 0.29 respectively at estimate by half-sib method (with out adjusted of maternal effect) but decreased to 0.36, 0.30, 0.32 and 0.25 (at birth) and 0.34, 0.34, 0.33 and 0.22 at the estimate by half-sib within adjusted of maternal effect. The variance of maternal effect of body measurements at birth were 4.403, 3.288, 3.736 and 3.921, at weaning were 6.822, 6.029, 5.264 and 6.438 of BL, HF, HG and C respectively. Whereas the variance of cytoplasmic were 0.805, 1.663, 0.885 and 0.847 at birth and 0.968, 0.894, 1.036 and 1.169 at weaning of BL, HF, HG and C respectively. There is variation estimate of genetic and phenotypic correlation between study traits with difference with out and within adjusted of maternal effect. | ||
