Milk partitioning, yield and composition were evaluated in purebred and crossbred goats as follows: 8 goats of Saanen breed, 8 of Damascus breed, 8 crossbreds Saanen x Local Greek goat, 8 backcrosses Saanen x Local Greek goat and 8 crossbreds Saanen x Alpine. Milk yield and milk fractions (machine milk, machine and hand stripped milk) were recorded twice a day. Milk partitioning ranged on satisfactory levels. Machine stripped milk varied from 12.2 to 23.4%, hand stripped milk from 5.4 to 11.9%. The effect of breed, lactation stage and animal was significant for all milk fractions. The effect of parity was also significant, except for stripped milks. Fat and protein concentrations (3.82-5.10% and 3.1-3.6%, resp.) were significantly influenced by the breed. Lactose conc. varied from 4.51 to 4.66%. Imported breeds and their crosses with Local Greek goat were characterized by good milkability. They may be machine milked without hand stripping.
