InCalf Fertility Data Project
Above: This research explored the change in reproductive performance in 74 Australian dairy herds over a decade
Client: Dairy Australia
Location: Victoria & Tasmania
Responsibilities: A longitudinal study of the reproductive performance of dairy herds
The need: Between 2000 and 2010, extension to improve the reproductive performance of dairy herds focused on management areas that had been identified in the original InCalf research. In 2010 concerns were raised that the national dairy herd fertility was declining and additional factors might be contributing to this decline. Dairy Australia established a research project to determine the facts behind these perceptions.
What we did: The Harris Park Group convened the Fertility Data Project Steering Committee, which designed and delivered this research, and facilitated agreement on priorities across a wide range of stakeholders. Dr John Morton provided expert epidemiological input, describing temporal trends and determining the factors that affected fertility for the 30 dairy herds in southern Australia with long term, reliable early pregnancy testing records, AI dates and culling records.
