N2  - The primary aim of this project was to determine the relevance of extended lactation to Victorian dairyfarmers, identifying the characteristics of those likely to be interested in the technology, and the type of information they require. This information was used to determine key questions and knowledge gaps for future scientific research and extension programs in extended lactation. Information was obtained from dairy farmers in 3 group discussions and 250 Computer Assisted Telephone Interviews (CATI). A structured questionnaire formed the basis of the CATI interviews. One in 10 respondents had implemented an extended lactation system with an average of 18.4% of their milking herd. The proportion interested in adopting an extended lactation system was 30%, increasing to 48% if calving inductions were prohibited. Potential future adopters were most likely to be split or batch calvers with large herds and high staff numbers. They were also the most likely to feed a heavy rate of concentrates (>1.5 t/cow), herd test and use management computer software. Of all cows currently in respondent herds, 56% were managed by dairy farmers who were either current or potential adopters of an extended lactation system. Benefits of an extended lactation system were perceived to include greater and more consistent production, consistent income, improved conception rates, improved cow health, fewer cows culled, and improved profitability. Disadvantages of the system were perceived to include higher feed costs, negative impacts on lifestyle (less opportunities to take holidays), difficult to manage and negative impacts on the physical condition of the farm. In addition, 3 group discussions were conducted with dairy service providers to determine their beliefs and perceptions of extended lactation technology. Service providers are key sources of information for dairy farmers. The studies identified that future scientific research, development and extension would need to provide information about the effect of an extended lactation system on: the economic feasibility of the system, nutritional requirements, cow health, production, conception rates, workloads and farm management strategies.
