The  study included 607 records for TMY and LP of 163 goats. The overall means for total milk yield through 179.54 days was 180.88 kg. The least squares means for milk yield 221.31 ± 6.40 , 149.84 ± 8.54 and 171.51 ± 11.21 kg  in Cyprus , Local goats and their cross , respectively  and lactation period were 172.51± 2.12 , 188.46 ± 2.90 and 177.67 ±  3.62 days in Cyprus , Local goats and their cross , respectively.  Genetic groups and production year were highly significant (P<0.01) on TMY and LP ,but type of birth and sex of kid were non- significant.
