Observed data from Donna Giltrap in New Zealand

• cattle:
  • Daily consumption: 4.6 kg C/head/day
• horse:
  • Daily consumption: 3.0 kg C/head/day
• sheep:
  • Daily consumption: 0.88 kg C/head/day

In all cases the nitrogen in the dung is 40 perc. of the total N, the C/N ratio for dung is 16 and the C/N ratio for urine is 0.5.
