Partners Networking to Advance South Island Dairying

West Coast Monitor Farm

estland has some unique challenges such as high rainfall and seasonal dry peroids which are variable across the region. Westland has now been collecting data for 10 years and continues to building on the information currently available.

This project funded by Westland Milk Products, DairyNZ, CRV Ambreed, ARL-Ravensdown and Rabobank aims to generate reliable pasture growth and quality, and soil temperature information, over the next 12 months, on two commercial dairy farms in Westland.

Farm walks schedule for this season are weekly from August to May, and monthly over the winter period.

Each week we will provide a Weekly Summary of information from the following regions:

Buller: Mawheraiti (Stu and Deb Bland), Westland: Kowhitirangi (Anna and Jeremy Hart).

Weekly Update as at week ending Wednesday 22 September 2021 

 CO Comment

 

More rain this week has seen growth still below levels many are used to by now. Be assured balance date is coming but it may be a bit later than usual. There are a range of balance dates across the Coast due to the geographical spread of the region and differing climates. Supplement in the form of good quality milking baleage is hard to find in any quantity. We need to stay mindful of this as the shortage may be evident for some time and could impact ability to stock up for next year if it is routinely purchased into the system.

 

In saying that the Mawheraiti monitor farm is organised to cut some silage at the runoff in a couple of weeks and are prepping to get the maize drilled too. The last of their maize has been fed to cows and they are opening them up on pasture to ensure they are fully fed.

 

The Kowhiterangi monitor farm has noted that it is still wet underfoot too with growth slower than normal. They have sent some surplus stock to the works in the form of cows that have shown up empty and some cows which are not performing. This will ensure they only have pregnant or productive animals on the property, and they are not feeding any passengers, to make the most of the feed available.

Notes:

253mm rain week of 19th. Moirs stop bank washed out causing river to go through our farm, washing our stop bank out and drowning water pump.

Took a few internal fences out and wrote boundary fence off.

Farm looking good for grass although ground conditions very soft on off-grazing springers.

Workshop finally usable so good to start on equipment maintenance, although a bit close to calving than normal.
