Abstract

This review examines the potential for extended lactations on Victorian dairy farms in the context of (i) the advantages and disadvantages of existing seasonal milk production systems; (ii) projected future changes to Victorian dairy farming; (iii) the mechanics of extended lactations; (iv) the change in costs associated with extended lactations; and (v) how extended lactations might be successfully implemented.

Successful implementation of this type of milk production system requires cows to calve in accordance with seasonal pasture supply. Recently a numb..
