A modelling approach to screen grazeable forage options for automatic milking system herds.
System fitness of grazeable forages for large herds in automatic milking system.
Modelling pasture-based automatic milking system herds: grazeable forage options.
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.
The same procedure was followed to calculate the farm size required for a CFS system that replaced pasture at 10%, 20%, 30%, 40%, and 50% level using grazeable CFR.
Strategic selection of high yielding grazeable forages in different seasons that have high growth and/or re-growth potential in summer (e.
Therefore, a modelling study was undertaken in order to investigate the potentials of APSIM to screen forages that can be grown to supply a high yield of grazeable forages for large AMS herds.
2011; Islam and Garcia, 2012) on annual cycle of a triple-crop CFR including simulations and validation of CFR using a range of N (0 to 523 kg/ha) and water (0 to 14 ML/ha) (Islam and Garcia 2010) and experimental data on triple-crop CFR rotations have created a level of confidence within the authors that APSIM is a suitable tool allowing the simulation and screening of potential grazeable forage rotations for AMS herds.
