Abstract
At the Agarguf Goat breeding station (30 Km west of Baghdad) , over 2005 , 116 records of grease fleece weight, fiber length, staple length and fiber diameter produced by 40 Goat (Namely local , Damascus , crossbred comprised Damascus X Local and crossbred comprised Saanen X Local) were analyzed statistically. The aim of this study was to investigate the effect of cytoplasmic inheritance and maternal effect in grease fleece weight, fiber length, staple length and fiber diameter. The SAS program was used to study in estimate of the Components of variance for the random effects in the employed mixed model was estimated by the Restricted Maximum Likelihood procedure. The Harvey program was also used to estimate BLUP values. The heritability of the grease fleece weight, fiber length, staple length and fiber diameter were 0.12, 0.15, 0.45 and 0.41 respectively at the heritability estimate by half-sib.whereas, increased the estimates to 0.16, 0.19, 0.47 and 0.53 at the estimate by daughter-dam and decreased to 0.09, 0.08, 0.42 and 0.36 respectively at the estimate by half-sib with adjusted of maternal effect. The variance of maternal effect in grease fleece weight, fiber length, staple length and fiber diameter were 215.34 , 113.95 , 206.04 and 9.88 whereas the variance of cytoplasmic were 9.39 , 2.035 , 16.87 and 0.131 respectively..BLUP (Best Linear Unbiased Prediction) estimates displayed a wide range among Goat included in the cur
