Research report part of the 'Revitalising calf rearing' project funded under Sustainable Food and Fibre Futures.

Within the dairy sector, several databases exist that have recorded farms, animals, and milk production over time, as well as feed use both through time and seasonally. This report assesses the feasibility of combining these databases to provide monthly estimates of feeds (grown on farm and imported) eaten by dairy cows from 1990 to 2020 for different types of farm systems and regions of New Zealand.

Faecal source tracking, water management, Norovirus, shellfish

Shellfish may become contaminated by potential human pathogens when they come into contact with water containing human sewage or agricultural runoff. MPI contracted ESR to identify and evaluate available chemical and microbial source tracking methods and technologies that could be used as indicators of human or animal faecal contamination, particularly in NZ shellfish growing areas, thereby offering opportunity to better manage these areas minimising commercial and public health impacts.
