Partners Networking to Advance South Island Dairying

West Coast Monitor Farm

Westland has some unique challenges such as high rainfall and seasonal dry peroids which are variable across the region. There is debate on how pasture growth rates and annual production on dairy farms throughout Westland compares to that collected from three years of monitoring on the Landcorp Kotuku Focus Farm. Westland has now been collecting data for 6 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 four 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: Westport (C Gallagher, Victoria Rd) Upper Grey Valley: Ikamatua (A Mirfin, Mirfins Rd) Greymouth: (A Robb Coal Creek, Taylorville Rd) Hokitika: Kowhitirangi (T&R Little, Whitcombe Valley Rd)

CO comment

Magnesium supplementation to dry cows will need to be started shortly to minimise the risk of grass staggers at calving. By reducing animal health problems the potential exists to increase milk production. Remember the magnesium requirement of the modern dairy cow has increased, partly due to increased use of nitrogen (N) and potassium (K) fertilisers and partly due to the increase in cow genetic merit increasing magnesium demand for milk production. Supplementation options include dusting Magnesium Oxide onto pasture, mixing Magnesium Oxide in silage, including Magnesium chloride or sulphate in drinking water or using Magnesium bullets. Getting in early and adopting the ‘prevention is better than cure’ method is the best approach. Talk with your vet for a mineral supplementation programme and go to the DairyNZ website (https://www.dairynz.co.nz/animal/cow-health/grass-staggers/) for further information.
