Lactation

Extended lactation is emerging as a potential option for dairy farmers looking to reduce labour pressure, improve flexibility and significantly cut the number of non-replacement calves being born each year. Anne Lee speaks with DairyNZ senior scientist Dr Paul Edwards about the research behind the system and the results emerging from farmlet trials at Scott Farm and a new study in Northland.

Could a 24-month calving interval ease spring workload and reduce non-replacement calves? After two years of research, DairyNZ is now working with a commercial farm to test the system – and early signs are promising. Words Dr Paul Edwards.
