We've been sharing some snapshots from Accelerating Change on social media. follow @Murray_Dairy and the tag #acceleratingchange to hear what project staff Amy Fay and Harriet Bawden and our farmers are discussing.
At the Stewart PIT meeting in December, the group reviewed the pasture accumulation data and nutritive values for the season so far. The group was put to the test to see if they could judge by eye the pasture mass and quality characteristics Accelerating Change has been collecting. One of our twitter followers guessed in first go! What do you reckon?

Accelerating Change Performance Innovation Teams met in November and December. A significant amount of the discussion focused on the group's summer feeding strategies, characterised by limited water availability and high prices.
Kelvin Matthews and Don Stewart are already seeing the results from improved data collection on farm. The nutritive sampling Accelerating Change has been conducting has revealed that their lucerne pasture was of excellent quality, much higher than the PIT group expected (ME 10.7, CP 29.4%, NDF 36.6% and ME 11.5, CP 33.2% & NDF 34.2%). Working with their nutritionist Andre Nel from Ridley's, they worked out their cows were receiving an extra 30 ME per day than required, and body condition score was increasing over time. Armed with this information they have reduced their grain intake by 1kg in the dairy, saving approximately 27c per cow per day. Over 500 cows this is a significant saving. Body condition is now being maintained. The herd will be monitored over ti...
The Stewart PIT spoke at length about the data that could be collected on the farm to inform some key management strategies for the group. In the first couple of meetings the watering strategy utilised on the farm, in particular the longer irrigation intervals that Kelvin and Don use, were of particular interest to the other farms in the group. Some felt that the longer intervals might be causing a yield penalty where others were keen to know if they could implement a longer irrigation interval to save on water use without compromising on pasture accumulation. The PIT team discussed the monitoring and measurement methodology and it was agreed that Accelerating Change would measure the impact of different watering strategies on the Stewart’s lucerne and perennial pastures.
The following methodology was agreed to. Each square represents a different irrigation bay.
On the Stewart farm, we are taking regular weekly readings to examine pasture growth at different irrigation intervals and on...
