Our results indicated that in an 800 cow herd, the incorporation of grazeable CFS into the farm system in association with pastures (30:70) had the potential to: i) reduce walking distances of large AMS herds by 1.
Risk and opportunities of grazeable complementary forage system
2012) in a modelling study reported that 28 t DM/ha/yr grazeable CFS is achievable compared to current 15 t DM/ha from pastures for AMS cows.
Thirty-six scenario analyses were carried out to investigate grazeable areas required for different herd sizes in pasture alone or CFS based AMS systems (Table 1).
Each of these herd sizes and pasture utilisation was incorporated with six levels of grazeable CFR (0%, 10%, 20%, 30%, 40%, and 50% of replacement of pasture by grazeable CFR) (Table 2).
The grazeable CFR consisted of a rotation of maize (Zea mays L.
One approach is to increase the amount of grazeable forages within a 1-km radius of the dairy.
Strategic selection of high yielding grazeable forages in different seasons that have high growth and/or re-growth potential in summer (e.
