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.
