Grazing treatments not working properly

[cranju]

Hi everyone,

I am trying to simulate three different treatments for sheep grazing- Controlled grazing (at least 2 months then rest 10 days and repeat), Variable grazing treatment (Current Practice in the farm: Jan-Feb nil, Mar 29th- Apr 12th x 107 ewe join, May-June nil, Jul 9th- 12th x 1200 ewes/wth, Aug nil) and high intensity grazing treatment (300 DSE/ha) for one day with 12 months rest period). I have tried to keep everything same except the treatments- right now I haven't used supplement as well for any of the treatments, but something seems off. There is not much decrease in above ground wt even if I increase the stocking rate by 10 times. In the variable and fixed treatment, the sheeps are not even grazing. Can anyone help me to identify what different should I do or what error I am making? For reference, I am attaching my simulation files attached here.
