Partners Networking to Advance South Island Dairying

P21 Telford Farmlet


Pastoral 21 is a collaborative venture between DairyNZ, Fonterra, Dairy Companies Association of New Zealand, Beef + Lamb NZ and the Ministry of Business, Innovation and Employment. Its goal is to provide accessible systems-level solutions for profitably increasing pastoral production while reducing farms’ environmental footprint. 

 

The Pastoral 21 farm system research is taking place at Scott Farm in Hamilton, Massey University in Palmerston North, Lincoln University Research Dairy Farm and Ashley Dene Farm in Lincoln, and Telford Farm near Balclutha.

 

The Southland/South Otago Trial is investigating two alternative approaches to wintering cows, together with modifications to the lactation production system to maintain productivity while reducing the environmental footprint.  One farm system is focusing on crop based wintering, investigating better feeding options to achieve body condition score targets and grazing management strategies to reduce sediment and phosphorus runoff.  On the milking platform associated with this treatment nitrogen fertiliser input has been reduced, cereal silage is grown as part of the system and fed during autumn and short rotation ryegrass cultivars are used to provide improved cool season growth.  The second system has cows housed in a barn and offered pasture silage during winter and is using duration controlled grazing  on the shoulders of the season to reduce urinary N return and reduce soil damage during wet spring conditions.

 General 

  • After drying all cows off in the coming week the dry matter allocation will be reduced to 10 kg/cow/day to stimulate the drying off process. 
  • Transitioning onto crop will commence around the 25th May
  • Dry cow therapy treatments are being applied based on individual cow SCC results for the season with low SCC cows only receiving teat seal.
  • Pasture growth rates are 15-20 kg DM/day higher than the feed budget 

CONTROL

  • PKE and pasture silage being used to fill any feed deficits.

RESTRICTED

  • Cows in barn overnight receiving 2kgDM pasture silage and 3kgDM PKE and grazing on pasture only during the day
  • Barn surface is staying clean, going through every day rotating the bark.

OPTIMAL

  • Maintain rotation length at 35-40 days
  • Receiving whole crop baleage conserved 2 months ago, as the whole crop bunker is now finished.
