Data were analyzed by the Least Squares Method and Maximum Likehood Function to determine the effects of some genetic and non-genetic factors affecting those traits. Harvey,1990 program was used to estimate some heritability, genetic and phenotypic correlations (rg, rp) on the studied traits of shami goat. Breeding value for total milk yield was ranged between (76 to 51- ), and Breeding value for lactation period was between (30 to 9-).

\nThe least squares means of total milk yield was 488\u00b122 kg.\u00a0 Sire, type, parity, year and the interaction between parity and year had highly significant effect on TMY. While the interaction between type and parity had no significant.
\nThe least squares means of lactation period was 226\u00b14 day. Year and the interaction between parity and year had highly significant. The Sire, parity had significant effect, while the type and the interaction between type and parity had no significant effect on LP.
\nEstimates of heritability were 0.20\u00b10.05 and 0.083\u00b10.04 TMY and LP, respectively. Also the prediction of genetic and\u00a0 phenotype correlation between the two studied traits were 0.529\u00b10.18 and 0.59\u00b1,respectively.
\nThe Repeatability for the two studied traits were 0.0549 and0.0546 respectively.
