What this clearly shows
👉 Feed isn’t the enemy — inefficiency is.
-
4–5 kg is the safest, most consistent zone across all milk prices
-
At 40c, overfeeding hurts — underfeeding also hurts
-
At 45c, good feed is clearly paying
-
At 50c, every efficient kg of nut is making money
-
Cutting from 4 kg to “save €0.68” often costs €1+ in milk
