| | + | Faecal sieving |
| | + | Faecal sieving was developed at the University of Florida |
| | + | (Hall 1999) using a standard kitchen sieve. Faecal samples |
| | + | are collected from the ground using a disposable coffee |
| | + | cup or similar vessel. Six to 12 samples should be collected |
| | + | per group of cows and sieved under running water. |
| | + | Samples should then be examined visually paying partic- 4 |
| | + | ular attention to both fibre length and the presence of |
| | + | undigested foodstuffs. Faecal fibre greater than 1.25 cm |
| | + | in length is suggestive of the presence of ruminal acidosis. |
| | + | The presence of undigested grains suggests ruminal |
| | + | acidosis, or poor harvesting or preparation techniques |
| | + | (eg, maize grains are not 'cracked' or inadequate caustic |
| | + | soda treatment of wheat). A common finding in cases of |
| | + | SARA is the presence of fibrin casts in faeces which indicate |
| | + | colonic mucosal damage. |
