Optiprill: South Island Summer Production

Don’t let production slide this summer.

When temperatures climb, milk and solids can dip. Cows eat less, ruminate less, and spend more time standing and panting. Balanced minerals help keep summer production steady by supporting appetite, rumen function, water and electrolyte balance, and resilience to heat.

What goes wrong in summer?

  • Heat stress from ~21°C: Lower intake, less rumination, drop in milk and fat test
  • Dehydration and electrolyte loss: Sluggish cows, poor cow flow
  • Oxidative stress: Tired cows, slower recovery after hot days
  • Rumen instability: Sorting feed, variable manure, off-flavours in the vat
  • Trace mineral shortfalls: Fertility lag, hoof and skin issues, slower return to peak
  • Palatability problems: Cows turn their noses up at plain minerals

How minerals help production stay strong

  • Salt (sodium) and potassium: keep fluids in balance so cows keep drinking and eating
  • Magnesium: helps nerves and muscles work well in the heat
  • Zinc and antioxidants: help skin and teats stay healthy; aid recovery after hot days
  • Copper, selenium, manganese, iodine: help immunity, metabolism, and milk quality
  • Phosphorus and calcium: help cows use energy and keep muscles working
  • Palatable carriers and flavours: cows actually eat the mix every day

Two Optiprill options for the South Island summer

Both products are designed for daily in-shed feeding with easy-flowing prills that mix cleanly and are made to be eaten.

Optiprill Summer

Built for hot, dry spells when cows need electrolytes and targeted trace minerals to keep eating and milking.

  • Focus: Heat stress over ~21°C, hydration support, skin and teat condition
  • Use when: Temps rise, cows pant, milk fat slips, water troughs are busy
  • Outcome: Steadier intakes, better cow attitude, more consistent vat results

Optiprill Performance

Daily mineral base for herds chasing stable milk and solids through the peak summer window.

  • Focus: Balanced macro and trace minerals for rumen function and production
  • Use when: You want a season-long base mix, with or without Optiprill Summer during hot weeks
  • Outcome: Consistent mineral cover, simple in-shed routine, reliable results
  • Learn more: Optiprill Performance

Choosing the right mix

  • Hot weeks forecast? Run Optiprill Performance as your base and add Optiprill Summer during heat spikes.
  • Already seeing heat signs? Shift to Optiprill Summer now, then return to Optiprill Performance when temps ease.
  • Palatability issues? Both Optiprill formulas include flavours cows actually eat, so minerals go in the cow, not the pit.

Simple, South Island-ready

  • Suits in-shed feeders across Canterbury, Otago and Southland
  • Flows cleanly, minimal dust, mixes well with grain or pellets
  • Backed by practical on-farm support from Agvance nutrition consultants
