THE RUMEN
EACH millilitre of rumenrumen digestive juice:
10 – 50 billionbillion MICROBES
1 millionmillion PROTOZOA
variable YEASTS & FUNGI
environmenenvironment of the rumen is ANAEROBIC
fermentation process of digestion: helped by these MICROBESMICROBES
(Bowen, 2006)
The interaction between the different speciesspecies of microbesmicrobes aid each in their metabolic
processes
WASTES that are produced from one species is the nutrient to the metabolism of another

THE RUMEN
(Bowen, 2006)
CELLULOLYTIC – DIGESTDIGEST cellulose
HEMICELLULOLYTIC – hemicellulose
AMYLOLYTIC – starch
PROTEOLYTIC – proteins
SUGAR utilizers – simple saccharides
AMMONIA producers
VITAMIN synthesisers
METHANE producers
LIST of the MICROBES MICROBES within:
(Bowen, 2006)
THE RUMEN is acidic: ‘BICARBONATE’ - is produced in saliva helps to maintain equilibrium
A COW produces 100 – 150 L per day
chewed feed - periodically returned from the rumen mouth where it is chewedchewed again
AN EXAMPLE:
COWS fed with grainsgrains have considerably lower concentrations cellulolytic species
(Wikipedia, 2008)
THE RUMEN pH is most favourable at : 6 – 7 severe pH fluctuations alter: microbe population
INTRODUCTION : new feed must be done:
– little and often
ALLOW normal/ gorge FEEDING DEPLETE A MICROBE TO EXTINCTION &
SERIOUS HEALTH EFFECTS CAN OCCUR
CARE is required : feeding the animal
