These practice changes result in lower emissions intensity per unit of product and a greater proportion of feed goes to milk production rather than maintenance.

|On farm change since 1990||Effect on farm productivity||Effect on emissions intensity (net)|
Consistent supply of high quality feed
Increased use of supplements (mazie sileage, PKE, brassicas)
Improved pasture, irrigation and fertilizer management
Improved genetic merit of animals through breeding and herd testing
Increased milk yield per cow (kg MS/cow)
Increased milk yield per hectare (kg MS/ha)
* Milk yield is closer to the animal's genetic potential*
* Greater proportion of feed goes to milk production rather than maintenance *
