Modelling Pasture-based Automatic Milking System Herds: The Impact of Large Herd on Milk Yield and Economics
Walking Distance Milking Interval Milk Yield Profit
2016/5/18
The aim of this modelling study was to investigate the effect of large herd size (and land areas) on walking distances and milking interval (MI), and their impact on milk yield and economic penalties ...
Modelling Pasture-based Automatic Milking System Herds: System Fitness of Grazeable Home-grown Forages, Land Areas and Walking Distances
Herd Size Walking Distance Grazeable Home-Grown Forages
2016/5/18
To maintain a predominantly pasture-based system, the large herd milked by automatic milking rotary would be required to walk significant distances. Walking distances of greater than 1-km are associat...
Modelling Pasture-based Automatic Milking System Herds: Grazeable Forage Options
Agricultural Production Systems Simulator Dairy Forage Options Forage Rotations
2016/5/18
One of the challenges to increase milk production in a large pasture-based herd with an automatic milking system (AMS) is to grow forages within a 1-km radius, as increases in walking distance increas...
