Feed Digestion Characteristics of Livestock Species, Related Methane Emission and Quality of Excreta.

Species | Specific (pre-) digestion abilities | CH4 production | Urine | Faeces | Manure use
poultry | Pre-digestion: feed is soaked in crop and grind in spear stomach | high from faeces if decomposition is anaerobic | Excreted with faeces N: uric acids | Excreted with urine DM: high N and P: high SOM: none Biodegradable Fibre: high | feed for ruminants bio gas fish pond fertiliser
pigs | strong stomach acid in stomach neutralise intake of contamination with feeds | high from faeces if decomposition is anaerobic | volume large N: uric acids | DM: medium SOM: low, NPK variable Biodegradable Fibre: high | bio gas fish pond fertiliser
sheep | grinding feed by rumination fibre fermentation in rumen some urea recycling at low N level of feed | mainly produced in rumen expelled by beck remaining in manure if anaerobic | volume small K: high; N: urea, variable | DM high SOM: moderate NPK variable Biodegradable Fibre: low | fertiliser compost starter
goats | Grinding feed by rumination fibre fermentation in rumen some urea recycling at low N level of feed | mainly produced in rumen expelled by beck remaining in manure if anaerobic | volume small K: high; N: urea, variable | DM: high SOM: moderate NPK variable Biodegradable Fibre low | fertiliser compost starter
cattle | Grinding feed by rumination fibre fermentation in rumen some urea recycling at low N level of feed | mainly produced in rumen expelled by beck remaining in manure if anaerobic | volume variable K: high; N: urea, variable | DM: variable SOM: high NPK variable Biodegradable Fibre: low | Dried as fuel Fertiliser Bio gas (slow) Mixed with compost/litter
camels | Grinding feed by rumination fibre fermentation in rumen strong urea recycling at low N level of feed | mainly produced in rumen expelled by beck remaining in manure if anaerobic | volume very small K: high; N: urea, variable | DM: high SOM: high NPK variable Biodegradable Fibre: low | Fertiliser
Equines | Teeth in lower and upper jaw, grinding feed before ingestion. Fibre fermentation in colon | Mainly produced in colon Expelled by anus Remaining in manure if anaerobic | volume variable K: high; N: variable | DM: high SOM: high NPK variable Biodegradable Fibre: low | Fertiliser
