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

Little sign of a surplus yet but its quick identification remains important. 

Mating management on a restricted budget reinforces the importance of heat detection.

Retaining the calving pattern and fertility of the herd for future years is an important part of regaining momentum as milk price lifts. Mating management should be business as usual with little to be gained from making “cuts”. In some cases, where calving pattern targets have not been met, doing more than usual is probably required. Most of the investment is time, not cash. Have simple systems in place, with people clear about their roles and actions required. 

Alterations such as OAD milking or 3 milkings in 2 days need to be handled with care as they can disrupt heat detection routines and timing of insemination in relation to standing heat. The evidence that short term reductions in milking frequency increases fertility are not strong. 

If proceeding with a synchrony programme and a group of animals has been identified to receive treatment, draught them out and get a couple of sets of eyes over them as you may have missed some of the subtle signs of pre mating heat due to wet weather conditions.
